Abstract
Influenza A (H1N1) viruses are prone to antigenic mutations and are more variable than other influenza viruses. Therefore, they have caused continuous harm to human public health since the pandemic in 2009 and in recent times. Influenza A (H1N1) can be prevented and treated in various ways, such as direct inhibition of the virus and regulation of human immunity. Among antiviral drugs, the use of natural products in treating influenza has a long history, and natural medicine has been widely considered the focus of development programs for new, safe anti-influenza drugs. In this paper, we focus on influenza A (H1N1) and summarize the natural product-derived phytochemicals for influenza A virus (H1N1) prevention and treatment, including marine natural products, flavonoids, alkaloids, terpenoids and their derivatives, phenols and their derivatives, polysaccharides, and derivatives of natural products for prevention and treatment of influenza A (H1N1) virus. We further discuss the toxicity and antiviral mechanism against influenza A (H1N1) as well as the druggability of natural products. We hope that this review will facilitate the study of the role of natural products against influenza A (H1N1) activity and provide a promising alternative for further anti-influenza A drug development.

Abstract
A novel actinomycete, designated RD004123T, was isolated from a soil sample collected in Hokkaido, Japan, and its taxonomic position was investigated by a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequence comparisons revealed that strain RD004123T fell within the cluster of the family Micromonosporaceae but did not form a reliable cluster with any member of the family. The similarity values between strain RD004123T and the type species of 29 genera in the family Micromonosporaceae were 91.7-97.7 %. Meanwhile, phylogenomic analyses indicated that strain RD004123T was closely related to members of the genus Phytohabitans. Strain RD004123T contained both meso-diaminopimelic acid and l-lysine as the diagnostic diamino acids of the peptidoglycan. The predominant isoprenoid quinones were MK-10(H8) and MK-10(H6), and the major fatty acids were anteiso-C17 : 0, iso-C16 : 0, iso-C15 : 0 and C17 : 0. The detected polar lipids were phosphatidylinositol mannosides, phosphatidylinositol, phosphatidylethanolamine and diphosphatidylglycerol. These chemotaxonomic features corresponded to those of the genus Phytohabitans. Meanwhile, the results of genome comparison analyses and phenotypic characterizations distinguished strain RD004123T from the other members of the genus Phytohabitans. Therefore, strain RD004123T should be assigned as representing a novel species of the genus Phytohabitans, for which the name Phytohabitans aurantiacus sp. nov. is proposed. The type strain is RD004123T (=NBRC 114997T=DSM 114330T).

Abstract
The name Micromonospora endophytica has been used for three different organisms. The first organism with this name is the species represented by strain DCWR9-8-2T, a species published in 2015 but whose name was never validated. In 2019 the type species of the genus Jishengella was reclassified into the genus Micromonospora, while maintaining its original epithet, thus establishing the second group of organisms known as M. endophytica, but the first for which the name was validated. Additionally, in 2018 the reclassification of the genus Verrucosispora into the genus Micromonospora was proposed, but a new epithet has not been specified for the species named Verrucosispora endophytica, which remains an orphaned species. Therefore, it is necessary to propose new names that can unequivocally identify these taxa. We have analysed the taxonomic position of the strains, comparing them with the species with valid published names of the genus Micromonospora. We here propose Micromonospora thawaii sp. nov. for the species represented by strain DCWR9-8-2T, and Micromonospora grosourdyae nom. nov. and Micromonospora sonchi comb. nov. for the two orphaned species of Verrucosispora, V. endophytica and Verrucosispora sonchi, respectively. Genomic analysis also showed that M. trujilloniae is a later heterotypic synonym of M. andamanensis.

Abstract
Actinobacteria constitute prolific sources of novel and vital bioactive metabolites for pharmaceutical utilization. In recent years, research has focused on exploring actinobacteria that thrive in extreme conditions to unearth their beneficial bioactive compounds for natural product drug discovery. Natural products have a significant role in resolving public health issues such as antibiotic resistance and cancer. The breakthrough of new technologies has overcome the difficulties in sampling and culturing extremophiles, leading to the outpouring of more studies on actinobacteria from extreme environments. This review focuses on the diversity and bioactive potentials/medically relevant biomolecules of extremophilic actinobacteria found from various unique and extreme niches. Actinobacteria possess an excellent capability to produce various enzymes and secondary metabolites to combat harsh conditions. In particular, a few strains have displayed substantial antibacterial activity against methicillin-resistant Staphylococcus aureus (MRSA), shedding light on the development of MRSA-sensitive antibiotics. Several strains exhibited other prominent bioactivities such as antifungal, anti-HIV, anticancer, and anti-inflammation. By providing an overview of the recently found extremophilic actinobacteria and their important metabolites, we hope to enhance the understanding of their potential for the medical world.

Abstract
Aging research aims at developing therapies that delay normal aging processes and some related pathologies. Recently, many compounds and extracts from natural products have been shown to slow aging and/or extend lifespan. Marine sponges and their associated microorganisms have been found to produce a wide variety of bioactive secondary metabolites; however, those from the Southwest of the Indian Ocean are much less studied, especially regarding anti-aging activities. In this study, the microbial diversity of the marine sponge Scopalina hapalia was investigated by metagenomic analysis. Twenty-six bacterial and two archaeal phyla were recovered from the sponge, of which the Proteobacteria phylum was the most abundant. In addition, 30 isolates from S. hapalia were selected and cultivated for identification and secondary metabolites production. The selected isolates were affiliated to the genera Bacillus, Micromonospora, Rhodoccocus, Salinispora, Aspergillus, Chaetomium, Nigrospora and unidentified genera related to the family Thermoactinomycetaceae. Crude extracts from selected microbial cultures were found to be active against seven clinically relevant targets (elastase, tyrosinase, catalase, sirtuin 1, Cyclin-dependent kinase 7 (CDK7), Fyn kinase and proteasome). These results highlight the potential of microorganisms associated with a marine sponge from Mayotte to produce anti-aging compounds. Future work will focus on the isolation and the characterization of bioactive compounds.

Abstract
A novel marine actinomycete, designated strain KJ-029T, was isolated from a marine sediment sample (water depth of 226 m) in Kagoshima, Japan. 16S rRNA gene sequence analysis revealed that the new isolate was most closely related to Micromonospora craniellae LHW 63014T (99.3 % similarity). Phylogenetic analyses of the genus Micromonospora based on 16S rRNA gene sequences showed that strain KJ-029T was clustered with Micromonospora craniellae LHW 63014T and Micromonospora endophytica 202201T. However, digital DNA-DNA hybridization analyses presented low levels of relatedness in the range of 24.8-32.9 % between strain KJ-029T and the above closely related strains. The novel strain contained meso-diaminopimelic acid and 3-OH-diaminopimelic acid, d-glutamic acid, glycine and d-alanine in the cell-wall peptidoglycan. The acyl type of the peptidoglycan was glycolyl and mycolic acids were absent. The major menaquinone was MK-9(H4). The whole-cell sugars consisted of glucose, mannose, xylose and ribose. Phosphatidylethanolamine was detected as the major phospholipid and corresponded to phospholipid type II. The predominant cellular fatty acid was iso-C16 : 0. The DNA G+C content of the genomic DNA was 71.5 mol%. Based on the present polyphasic study, strain KJ-029T represents a novel species of the genus Micromonospora, for which the name Micromonospora pelagivivens sp. nov. is proposed. The type strain is KJ-029T (=NBRC 113519T=TBRC 9233T).

Abstract
The phyllosphere referred to the total aerial plant surfaces (above-ground portions), as habitat for microorganisms. Microorganisms establish compositionally complex communities on the leaf surface. The microbiome of phyllosphere is rich in diversity of bacteria, fungi, actinomycetes, cyanobacteria, and viruses. The diversity, dispersal, and community development on the leaf surface are based on the physiochemistry, environment, and also the immunity of the host plant. A colonization process is an important event where both the microbe and the host plant have been benefited. Microbes commonly established either epiphytic or endophytic mode of life cycle on phyllosphere environment, which helps the host plant and functional communication with the surrounding environment. To the scientific advancement, several molecular techniques like metagenomics and metaproteomics have been used to study and understand the physiology and functional relationship of microbes to the host and its environment. Based on the available information, this chapter describes the basic understanding of microbiome in leaf structure and physiology, microbial interactions, especially bacteria, fungi, and actinomycetes, and their adaptation in the phyllosphere environment. Further, the detailed information related to the importance of the microbiome in phyllosphere to the host plant and their environment has been analyzed. Besides, biopotentials of the phyllosphere microbiome have been reviewed.

Abstract
A novel marine actinomycete, designated LHW63014T, isolated from a marine sponge, Craniella species, collected in the South China Sea, was examined using a polyphasic approach. The 16S rRNA gene sequence of strain LHW63014T showed highest similarities to Jishengella endophytica 202201T (98.9 %), Micromonospora olivasterospora DSM 43868T (98.7 %), Micromonospora maris AB-18-032T (98.6 %) and Micromonospora gifhornensis DSM 44337T (98.6 %). Phylogenetic analyses of the family Micromonosporaceae based on the 16S rRNA and gyrB gene sequences indicated that strain LHW63014T and J. endophytica 202201T located within the genus Micromonospora. Morphological and chemotaxonomic characteristics confirmed their affiliation to the genus Micromonospora. Based on phenotypic characteristics, phylogenetic data and digital DNA-DNA hybridization results, strain LHW63014T could be distinguished from its closest taxa, representing a novel species of the genus Micromonospora, for which the name Micromonospora craniellae sp. nov., is proposed, with the type strain LHW63014T (=DSM 106193T=CCTCC AA 2018012T). It is also proposed that J. endophytica be transferred to genus Micromonospora as Micromonospora endophytica comb. nov. (type strain 202201T =CGMCC 4.5597T=DSM 45430T).

Abstract
Two novel actinomycetes, designated strains ZLN81T and ZLN712T, were isolated from a frozen soil sample which was collected from the Arctic region. Chemotaxonomic and morphological characteristics were found to be typical of members of the genus Streptomyces. Based on 16S rRNA gene sequence analyses, the two strains show high similarity with Streptomyces polygonati NEAU-G9T (99.45%, 99.17%) and Streptomyces yanglinensis 1307T (98.17%, 98.10%). DNA-DNA relatedness between each of the strains and their close phylogenetic neighbours showed that they belonged to distinct species. Multilocus sequence analysis (MLSA) using four housekeeping genes (atpD, gyrB, recA and rpoB) for comparing Streptomyces type strains showed that the MLSA distance of strains ZLN81T and ZLN712T to the closely related species was greater than the 0.007 threshold. The cell wall amino acids of the two strains were identified as alanine, glycine, asparagine, ll-diaminopimelic acid and meso-diaminopimelic acid. The whole cell sugars were identified as galactose and glucose for strain ZLN81T and galactose, glucose and xylose for strain ZLN712T. The predominant menaquinones were identified as MK-10(H8), MK-9(H4) and MK-9(H6) for strain ZLN81T and MK-9(H0), MK-10(H8) and MK-9(H6) for strain ZLN712T. The polar lipid profile of strain ZLN81T was found to contain diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannosides and two unidentified phospholipids, while that of strain ZLN712T consisted of diphosphatidylglycerol, phosphatidylethanolamine, a ninhydrin-positive glycophospholipid, phosphatidylinositol mannosides and two unidentified phospholipids. The major fatty acids were identified as iso-C16:0, anteiso-C17:0, C16:0 and anteiso-C15:0 for strain ZLN81T and iso-C16:0, C16:0, anteiso-C15:0 and iso-C14:0 for strain ZLN712T. The DNA G+C contents were found to be 73.96 and 72.77 mol% for strains ZLN81T and ZLN712T, respectively. On the basis of these phenotypic and genotypic data, strains ZLN81T (= CCTCC AA 2018010T = DSM 107255T) and ZLN712T (= CCTCC AA 2018011T = DSM 107266T) are concluded to represent two novel species of the genus Streptomyces, for which the names Streptomyces polaris sp. nov. and Streptomyces septentrionalis sp. nov. are proposed, respectively.

Abstract
A novel actinomycete, strain PLAI 1-1T, which formed spiny single spore directly on substrate mycelium was isolated from root tissue of Zingiber montanum. The isolate contained meso-diaminopimelic acid and 3-hydroxydiaminopimelic acid in the cell-wall peptidoglycan. The acyl type of the cell-wall muramic acid was glycolyl. The whole-cell sugars of strain PLAI 1-1T were glucose, arabinose, xylose, ribose and a trace amount of mannose. The membrane phospholipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylserine and phosphatidylinositol. The major menaquinone was MK-9 (H4). The main cellular fatty acids were iso-C15 : 0 and C17 : 1ω8c. The G+C content of the genomic DNA was 70.6 mol%. 16S rRNA gene sequence analysis revealed that strain PLAI 1-1T was a member of the genus Jishengella and had the highest 16S rRNA gene sequence similarity to Jishengella endophytica DSM 45430T (99.2 %). Based on the data of physiological and biochemical tests, including the result of DNA-DNA hybridization, strain PLAI 1-1T represents a novel species of the genus Jishengella, for which the name Jishengellazingiberis sp. nov. is proposed. The type strain is PLAI 1-1T (=TBRC 7644T=NBRC 113144T).

Abstract
Actinobacteria are wide spread in nature and represent the largest taxonomic group within the domain Bacteria. They are abundant in soil and have been extensively explored for their therapeutic applications. This versatile group of bacteria has adapted to diverse ecological habitats, which has drawn considerable attention of the scientific community in recent times as it has opened up new possibilities for novel metabolites that may help in solving some of the most challenging problems of the day, for example, novel drugs for drug-resistant human pathogens, affordable means to maintain ecological balance in various habitats, and alternative practices for sustainable agriculture. Traditionally, free dwelling soil actinobacteria have been the subject of intensive research. Of late, symbiotic actinobacteria residing as endophytes within the plant tissues have generated immense interest as potential source of novel compounds, which may find applications in medicine, agriculture, and environment. In the light of these possibilities, this review focuses on the diversity of endophytic actinobacteria isolated from the plants of extreme habitats and specific ecological niches. Furthermore, an attempt has been made to assign chemical class to the compounds obtained from endophytic actinobacteria. Potential therapeutic applications of these compounds and the utility of endophytic actinobacteria in agriculture and environment are discussed.

Abstract
Endophytic actinobacteria are one of the important pharmaceutical resources and well known for producing different types of bioactive substances. Nevertheless, detection of the novelty, diversity, and bioactivity on endophytic actinobacteria isolated from mangrove plants are scarce. In this study, five different mangrove plants, Avicennia marina, Aegiceras corniculatum, Kandelia obovota, Bruguiera gymnorrhiza, and Thespesia populnea, were collected from Beilun Estuary National Nature Reserve in Guangxi Zhuang Autonomous Region, China. A total of 101 endophytic actinobacteria strains were recovered by culture-based approaches. They distributed in 7 orders, 15 families, and 28 genera including Streptomyces, Curtobacterium, Mycobacterium, Micrococcus, Brevibacterium, Kocuria, Nocardioides, Kineococcus, Kytococcus, Marmoricola, Microbacterium, Micromonospora, Actinoplanes, Agrococcus, Amnibacterium, Brachybacterium, Citricoccus, Dermacoccus, Glutamicibacter, Gordonia, Isoptericola, Janibacter, Leucobacter, Nocardia, Nocardiopsis, Pseudokineococcus, Sanguibacter, and Verrucosispora. Among them, seven strains were potentially new species of genera Nocardioides, Streptomyces, Amnibacterium, Marmoricola, and Mycobacterium. Above all, strain 8BXZ-J1 has already been characterized as a new species of the genus Marmoricola. A total of 63 out of 101 strains were chosen to screen antibacterial activities by paper-disk diffusion method and inhibitors of ribosome and DNA biosynthesis by means of a double fluorescent protein reporter. A total of 31 strains exhibited positive results in at least one antibacterial assay. Notably, strain 8BXZ-J1 and three other potential novel species, 7BMP-1, 5BQP-J3, and 1BXZ-J1, all showed antibacterial bioactivity. In addition, 21 strains showed inhibitory activities against at least one "ESKAPE" resistant pathogens. We also found that Streptomyces strains 2BBP-J2 and 1BBP-1 produce bioactive compound with inhibitory activity on protein biosynthesis as result of translation stalling. Meanwhile, Streptomyces strain 3BQP-1 produces bioactive compound inducing SOS-response due to DNA damage. In conclusion, this study proved mangrove plants harbored a high diversity of cultivable endophytic actinobacteria, which can be a promising source for discovery of novel species and bioactive compounds.

Abstract
Two actinobacterial isolates, strains SG15T and SGB14T, were recovered through a microbial diversity study of nitrogen fixing nodules from Pisum sativum plants collected in Salamanca (Spain). The taxonomic status of these isolates was determined using a polyphasic approach and both presented chemotaxonomic and morphological properties consistent with their classification in the genus Micromonospora. For strains SG15T and SGB14T, the highest 16S rRNA gene sequence similarities were observed with Micromonospora coxensis JCM 13248T (99.2 %) and Micromonospora purpureochromogenes DSM 43821T (99.4 %), respectively. However, strains SG15T and SGB14T were readily distinguished from their phylogenetic neighbours both genetically and phenotypically indicating that they represent two new Micromonospora species. The following names are proposed for these species: Micromonosporaphytophila sp. nov. type strain SG15T (=CECT 9369T; =DSM 105363T), and Micromonosporaluteiviridis sp. nov. type strain SGB14T (=CECT 9370T; =DSM 105362T).

Abstract
A novel actinomycete, designated strain 2902at01T was isolated from soil collected at a mangrove forest in Zhanjiang, Guangdong province, China. The strain was identified using a polyphasic classification method. The 16S rRNA gene sequence of strain 2902at01T showed the highest similarity to Micromonospora equina Y22T (98.3 %) and Micromonospora pattaloongensis TJ2-2T (98.1 %). Phylogenetic analysis based on the gyrB gene sequence also clearly showed that the strain was different from any previously discovered species of the genus Micromonospora. The characteristic whole-cell sugars were ribose and xylose. The cell-wall hydrolysates contained alanine, asparagine, glycine and meso-diaminopimelic acid. MK-10(H6) and MK-10(H8) were the major menaquinones of the novel strain. The predominant fatty acids were iso-C15 : 0, anteiso-C15 : 0 and iso-C16 : 0. The characteristic polar lipids of strain 2902at01T were phosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol mannoside and diphosphatidylglycerol. The DNA G+C content was 70.2 mol%. DNA–DNA hybridization data combined with other physiological and biochemical features could distinguish strain 2902at01T from the reference strains M. equina Y22T and M. pattaloongensis TJ2-2 T. On the basis of these phenotypic and genotypic data, strain 2902at01T represents a novel species of the genus Micromonospora, for which the name Micromonospora zhanjiangensis sp. nov. is proposed. The type strain is 2902at01T ( = CCTCC AA2014018T = DSM 45902T).

Abstract
Actinobacteria are one of the most important and efficient groups of natural metabolite producers. The genus Streptomyces have been recognized as prolific producers of useful natural compounds as they produced more than half of the naturally-occurring antibiotics isolated to-date and continue as the primary source of new bioactive compounds. Lately, Streptomyces groups isolated from different environments produced the same types of compound, possibly due to frequent genetic exchanges between species. As a result, there is a dramatic increase in demand to look for new compounds which have pharmacological properties from another group of Actinobacteria, known as rare actinobacteria; which is isolated from special environments such as mangrove. Recently, mangrove ecosystem is becoming a hot spot for studies of bioactivities and the discovery of natural products. Many novel compounds discovered from the novel rare actinobacteria have been proven as potential new drugs in medical and pharmaceutical industries such as antibiotics, antimicrobials, antibacterials, anticancer, and antifungals. This review article highlights the latest studies on the discovery of natural compounds from the novel mangrove rare actinobacteria and provides insight on the impact of these findings.

Abstract
Plant growth promoting (PGP) bacteria are involved in various interactions known to affect plant fitness and soil quality, thereby increasing the productivity of agriculture and stability of soil. Although the potential of actinobacteria in antibiotic production is well-investigated, their capacity to enhance plant growth is not fully surveyed. Due to the following justifications, PGP actinobacteria (PGPA) can be considered as a more promising taxonomical group of PGP bacteria: (1) high numbers of actinobacteria per gram of soil and their filamentous nature, (2) genome dedicated to the secondary metabolite production (~5 to 10 %) is distinctively more than that of other bacteria and (3) number of plant growth promoter genera reported from actinobacteria is 1.3 times higher than that of other bacteria. Mechanisms by which PGPA contribute to the plant growth by association are: (a) enhancing nutrients availability, (b) regulation of plant metabolism, (c) decreasing environmental stress, (d) control of phytopathogens and (e) improvement of soil texture. Taxonomical and chemical diversity of PGPA and their biotechnological application along with their associated challenges are summarized in this paper.

Abstract
Mangroves are woody plants located in tropical and subtropical intertidal coastal regions. The mangrove ecosystem is becoming a hot spot for natural product discovery and bioactivity survey. Diverse mangrove actinomycetes as promising and productive sources are worth being explored and uncovered. At the time of writing, we report 73 novel compounds and 49 known compounds isolated from mangrove actinomycetes including alkaloids, benzene derivatives, cyclopentenone derivatives, dilactones, macrolides, 2-pyranones and sesquiterpenes. Attractive structures such as salinosporamides, xiamycins and novel indolocarbazoles are highlighted.

[PMID: 24451190 PMCID: PMC3917282 DOI: 10.3390/md12010477] [Citation(s) in RCA: 45] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2013] [Revised: 12/24/2013] [Accepted: 01/07/2014] [Indexed: 11/25/2022] Open
Abstract
A new alkaloid, 2-(furan-2-yl)-6-(2S,3S,4-trihydroxybutyl)pyrazine (1), along with 12 known compounds, 2-(furan-2-yl)-5-(2S,3S,4-trihydroxybutyl)pyrazine (2), (S)-4-isobutyl-3-oxo-3,4-dihydro-1H-pyrrolo[2,1-c][1,4]oxazine-6-carbaldehyde (3), (S)-4-isopropyl-3-oxo-3,4-dihydro-1H-pyrrolo[2,1-c][1,4]oxazine-6-carbaldehyde (4), (4S)-4-(2-methylbutyl)-3-oxo-3,4-dihydro-1H-pyrrolo[2,1-c][1,4]oxazine-6-carbaldehyde (5), (S)-4-benzyl-3-oxo-3,4-dihydro-1H-pyrrolo[2,1-c][1,4]oxazine-6-carbaldehyde (6), flazin (7), perlolyrine (8), 1-hydroxy-β-carboline (9), lumichrome (10), 1H-indole-3-carboxaldehyde (11), 2-hydroxy-1-(1H-indol-3-yl)ethanone (12), and 5-(methoxymethyl)-1H-pyrrole-2-carbaldehyde (13), were isolated and identified from the fermentation broth of an endophytic actinomycetes, Jishengella endophytica 161111. The new structure 1 and the absolute configurations of 2–6 were determined by spectroscopic methods, J-based configuration analysis (JBCA) method, lactone sector rule, and electronic circular dichroism (ECD) calculations. Compounds 8–11 were active against the influenza A virus subtype H1N1 with IC50 and selectivity index (SI) values of 38.3(±1.2)/25.0(±3.6)/39.7(±5.6)/45.9(±2.1) μg/mL and 3.0/16.1/3.1/11.4, respectively. The IC50 and SI values of positive control, ribavirin, were 23.1(±1.7) μg/mL and 32.2, respectively. The results showed that compound 9 could be a promising new hit for anti-H1N1 drugs. The absolute configurations of 2–5, 13C nuclear magnetic resonance (NMR) data and the specific rotations of 3–6 were also reported here for the first time.

Abstract
A novel endophytic actinomycete, designated strain NEAU-J3(T), was isolated from soybean root (Glycine max (L.) Merr) and characterized using a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequences suggested that strain NEAU-J3(T) fell within the family Micromonosporaceae. The strain was observed to form an extensively branched substrate mycelium, which carried non-motile oval spores with a smooth surface. The cell walls of strain NEAU-J3(T) were determined to contain meso-diaminopimelic acid and galactose, ribose and glucose were detected as whole-cell sugars. The major menaquinones were determined to be MK-9(H(4)) and MK-9(H(6)). The phospholipids detected were phosphatidylcholine and phosphatidylethanolamine. The major cellular fatty acids were determined to be C(16:0), C(18:1) ω9c, C(18:0), C(17:0), C(17:1) ω7c, anteiso-C(17:0), C(16:1) ω7c and C(15:0). The DNA G + C content was 62.5 mol%. On the basis of the morphological and chemotaxonomic characteristics, phylogenetic analysis and characteristic patterns of 16S rRNA gene signature nucleotides, strain NEAU-J3(T) is considered to represent a novel species of a new genus within the family Micromonosporaceae, for which the name Wangella harbinensis gen. nov., sp. nov. is proposed. The type strain of Wangella harbinensis is strain NEAU-J3(T) (=CGMCC 4.7039(T) = DSM 45747(T)).

Abstract
A novel endophytic actinomycete, strain 274745(T), was isolated from a root of Sonneratia apetala collected in a mangrove forest in Sanya, Hainan province, China. The 16S rRNA gene sequence of strain 274745(T) showed the greatest similarity to Micromonospora pattaloongensis TJ2-2(T) (98.3 %). Phylogenetic analysis based on the gyrB gene also supported the close relationship of these two strains. The predominant menaquinone was MK-10(H8) and the major fatty acids were iso-C15 : 0, C17 : 0 and anteiso-C15 : 0. The characteristic whole-cell sugars were xylose and mannose. The cell wall contained meso-diaminopimelic acid and glycine. The polar lipid profile mainly comprised phosphatidylethanolamine, phosphatidylinositol and diphosphatidylglycerol. The DNA G+C content was 71.6 mol%. Furthermore, a combination of DNA-DNA relatedness and some physiological and biochemical properties indicated that the novel strain could be readily distinguished from the closest phylogenetic relatives. On the basis of these phenotypic and genotypic data, strain 274745(T) represents a novel species of the genus Micromonospora, for which the name Micromonospora sonneratiae sp. nov. is proposed. The type strain is 274745(T) ( = CCTCC AA 2012003(T) = DSM 45704(T)).

Abstract
A novel endophytic actinomycete, strain YIM 65646T, was isolated from the roots of Artemisia annua L. collected from Yunnan Province, south-west China. Growth was observed in the temperature range 10–40 °C (optimum 20–28 °C) and at pH 6.0–9.0 (optimum pH 7.0). The organism formed well-developed, branched substrate mycelia, but aerial mycelium was not produced. Phenotypic characterization and 16S rRNA gene sequence analysis indicated that strain YIM 65646T belonged to the family Micromonosporaceae (sharing ≤93.6 % sequence similarity with members of this family) and formed a distinct clade in the Micromonosporaceae phylogenetic tree. The strain contained meso-diaminopimelic acid in the cell wall and mannose, ribose, galactose and glucose in whole-cell hydrolysates. The major menaquinones were MK-10(H4), MK-10(H2), MK-8(H2), MK-9(H2) and MK-10(H6). The major fatty acids were iso-C15 : 0, anteiso-C15 : 0, anteiso-C17 : 0, iso-C17 : 0 and iso-C16 : 0. The DNA G+C content of strain YIM 65646T was 70.0 mol%. On the basis of morphological and chemotaxonomic properties and phylogenetic analysis based on 16S rRNA gene sequence data, it is proposed that this strain should be classified in a novel genus and species, Phytomonospora endophytica gen. nov., sp. nov., in the family Micromonosporaceae. The type strain is YIM 65646T ( = CCTCC AA 209041T = DSM 45386T).
