Abstract
Bean yellow mosaic virus (BYMV) is the one of most prevalent and harmful viruses infecting gladiolus plants worldwide. The aim of the study was to perform phylogenetic analysis of two Ukrainian BYMV isolates from gladioli grown in different regions of Ukraine and determine phylogenetic relationships of the isolates to other BYMVs. Visual diagnostics, enzyme-linked immunosorbent assay in DAS-ELISA modification, total RNA extraction, RT-PCR, phylogenetic analysis and statistical data analysis were used in this research. The results of the studies showed that gladioli of variety Pamyat’ (Poltava region, 2018) and var. Galyna Zelenobirska (Kyiv region, 2020) with symptoms of chlorotic stripes and mosaics on the leaves, flower color breaks are infected by BYMV. Fragments of the CP gene sequence of Ukrainian gladiolus isolates of bean yellow mosaic virus, named GlMP-18 (MK416160) and BYMV-Gl-SV-20 (MZ286966) were sequenced and deposited to the NCBI GenBank. Nucleotide sequences of these isolates corresponding to 578 nt of the coat protein gene (CP) located at the position 8727–9305 of the viral genome and amino acid sequences were compared with 40 known BYMV isolates/strains. Phylogenetic analysis demonstrated that GlMP-18 and BYMV-Gl-SV-20 have identity of nucleotide sequence 100% and amino acid sequence 100% with each other. Both Ukrainian isolates clustered with the Monocot group. The identity of the СР gene sequences of the two gladiolus isolates GlMP-18 and BYMV-Gl-SV-20 from geographically remote regions of the country and in different years of selection indicates a common origin of isolates and probable their distribution of planting material.

Abstract
During the growing season of 2018, several field-grown cucurbit plants in different parts of Iraq and Iran were surveyed for the presence of zucchini yellow mosaic virus (ZYMV), using two degenerate primer pairs (CIF/Rev and NIb2F/3R) targeting the two separated partial regions of the potyvirus genome (CI and NIb respectively). 7 out of 20 samples were confirmed to be infected with ZYMV. Phylogenetic analyses based on the CI gene grouped all Iranian and two Iraqi (ZYMV1 and ZYMV2) isolates together with isolates from the Middle East in the subgroup (AI), whereas the other Iraqi (ZYMV3 and ZYMV4) isolates were clustered in the subgroup (DI), which was only consisted of American isolates. The highest and lowest identity between the studied isolates and the GenBank isolates showed that the two genes (CI, NIb) of each isolate particularly the Iraqi isolates were more similar to a specific and geographically scattered mosaic of worldwide isolates, suggestive of mixed infection might have occurred between different worldwide isolates in Iraq. Furthermore, the first complete nucleotide sequence of an Iraqi ZYMV (ZYMV-Iq) isolate was done, using the Illumina sequencing technique. The complete nucleotide sequence of ZYMV-Iq isolate was 9650 nt, excluding the 3'poly (A) tail. ZYMV-Iq isolate shared the highest nt identity of 98.8% with an American (KC665630) isolate. Phylogenetic analysis based on the full genome sequence placed ZYMV-Iq in subgroup A of group I alongside 18 isolates from the US and two isolates from Australia. In addition, recombination analysis detected lone significant recombination between ZYMV-Iq and South Korean (AY279000) isolate. Moreover, the results showed that symptom intensity was varied across experimental host plants.

Abstract
We report the complete genome sequence of five bean yellow mosaic virus (BYMV) isolates (CK-GL1, CK-GL3, CK-GL4, CK-GL5 and Vfaba2) that share 74.6-98.9% (nucleotide) and 81.5-99.1% (amino acid) identity with globally available BYMV sequences. Phylogenetic analysis clustered them specifically in BYMV phylogenetic group-IV within the existing nine groups. The CK-GL1, CK-GL2, CK-GL4 and CK-GL5 isolates formed a discrete cluster within group-IV. The present study suggests subdivision of group-IV into subgroup-IVa and IVb. Moreover, infectivity assays using in vitro RNA transcripts from subgroup-IVa (CK-GL3 isolate) and IVb (CK-GL1 isolate) showed distinct biological differences between the isolates supporting subdivision.

Identification and molecular characterization of Bean yellow mosaic virus infecting French bean in Himachal Pradesh. Virusdisease 2015; 26:315-8. [PMID: 26645043 DOI: 10.1007/s13337-015-0270-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2015] [Accepted: 07/30/2015] [Indexed: 10/23/2022] Open
Abstract
French bean (Phaseolus vulgaris L.), is one of the most widely grown vegetable crop. Disease samples showing yellow mosaic symptoms on leaves and pods were collected from Himachal Pradesh and inoculated on common bean cv. Jawala through sap inoculation. The virus successfully transmitted by mechanical inoculation produced yellow mosaic, leaf distortion, curling, wrinkling of leaves followed by stunting of plants. The identity of the virus as Bean yellow mosaic virus (BYMV) was established through Double antibody sandwich-enzyme linked immunosorbent assay, multiple sequence alignment and phylogenetic analysis of the coat protein gene sequence amplified by reverse transcription-polymerase chain reaction. The cp gene contained 819 nucleotides potentially coding for 273 amino acids. The sequence showed 83-99 % nucleotide and 89-99 % amino acid sequence identities with other BYMV isolates/strains and shared maximum identity with BYMV strain reported from Gladiolus sp. in Japan. This study constitutes the first report of BYMV occurrence on P. vulgaris in Himachal Pradesh.

Abstract
Bean yellow mosaic virus (BYMV), genus Potyvirus, has an extensive natural host range encompassing both dicots and monocots. Its phylogenetic groups were considered to consist of an ancestral generalist group and six specialist groups derived from this generalist group during plant domestication. Recombination was suggested to be playing a role in BYMV's evolution towards host specialization. However, in subsequent phylogenetic analysis of whole genomes, group names based on the original hosts of isolates within each of them were no longer supported. Also, nine groups were found and designated I-IX. Recombination analysis was conducted on the complete coding regions of 33 BYMV genomes and two genomes of the related Clover yellow vein virus (CYVV). This analysis found evidence for 12 firm recombination events within BYMV phylogenetic groups I-VI, but none within groups VII-IX or CYVV. The greatest numbers of recombination events within a sequence (two or three each) occurred in four groups, three which formerly constituted the single ancestral generalist group (I, II and IV), and group VI. The individual sequences in groups III and V had one event each. These findings with whole genomes are consistent with recombination being associated with expanding host ranges, and call into question the proposed role of recombination in the evolution of BYMV, where it was previously suggested to play a role in host specialization. Instead, they (i) indicate that recombination explains the very broad natural host ranges of the three BYMV groups which infect both monocots and dicots (I, II, IV), and (ii) suggest that the three groups with narrow natural host ranges (III, V, VI) which also showed recombination now have the potential to reduce host specificity and broaden their natural host ranges.

Abstract
Diseases of viral origin in humans are among the most serious threats to health and the global economy. As recent history has shown the virus has a high pandemic potential, among other reasons, due to its ability to spread by air, hence the identification, investigation, containment, and treatment of viral diseases should be considered of paramount importance. In this sense, the bioinformatics research has focused on finding fast and efficient algorithms that can identify highly toxic antiviral peptides and to serve as a first filter, so that trials in the laboratory are substantially reduced. The work presented here contributes to this effort through the use of an algorithm already published by this team, called polarity index method, which identifies with high efficiency antiviral peptides from the exhaustive analysis of the polar profile, using the linear sequence of the peptide. The test carried out included all peptides in APD2 Database and 60 antiviral peptides identified by Kumar and co-workers (Nucleic Acids Res 40:W199-204, 2012), to build its AVPpred algorithm. The validity of the method was focused on its discriminating capacity so we included the 15 sub-classifications of both Databases.

Abstract
Bean common mosaic virus (BCMV) exists as a complex of strains classified by reactions to resistance genes found in common bean (Phaseolus vulgaris); seven BCMV pathotypes have been distinguished thus far, numbered I to VII. Virus genetic determinants involved in pathogenicity interactions with resistance genes have not yet been identified. Here, we describe the characterization of two novel field isolates of BCMV that helped to narrow down these genetic determinants interacting with specific P. vulgaris resistance factors. Based on a biological characterization on common bean differentials, both isolates were classified as belonging to pathotype VII, similar to control isolate US10, and both isolates exhibited the B serotype. The whole genome was sequenced for both isolates and found to be 98 to 99% identical to the BCMV isolate RU1 (pathotype VI), and a single name was retained: BCMV RU1-OR. To identify a genetic determinant of BCMV linked to the BCMV pathotype VII, the whole genome was also sequenced for two control isolates, US10 and RU1-P. Inspection of the nucleotide sequences for BCMV RU1-OR and US10 (both pathotype VII) and three closely related sequences of BCMV (RU1-P, RU1-D, and RU1-W, all pathotype VI) revealed that RU1-OR originated through a series of recombination events between US10 and an as-yet-unidentified BCMV parental genome, resulting in changes in virus pathology. The data obtained suggest that a fragment of the RU1-OR genome between positions 723 and 1,961 nucleotides that is common to US10 and RU1-OR in the P1-HC-Pro region of the BCMV genome may be responsible for the ability to overcome resistance in bean conferred by the bc-2(2) gene. This is the first report of a virus genetic determinant responsible for overcoming a specific BCMV resistance gene in common bean.

Abstract
ABSTRACT A strain of Bean common mosaic necrosis virus (BCMNV) from Idaho was identified by enzyme-linked immunosorbent assay using monoclonal antibodies and determined to be similar to the NL-3 D strain (of Drifjhout) by reaction of differential bean cultivars. However, this BCMNV strain (designated NL-3 K) caused earlier and more severe symptoms on bean plants representing host groups 0, 4, and 5. The nucleotide sequence encoding the predicted polyprotein of NL-3 K was 9,893 nucleotides (nt) in length, yielding a peptide with a molecular size of 362.1 kDa compared with a 9,626-nt, 350.9-kDa polyprotein for NL-3 D. Sequence analysis of the putative P1 protein suggests that the NL-3 K strain is a recombinant between NL-3 D and the Russian strain (RU1) of Bean common mosaic virus. The P1 protein of NL-3 K consisted of 415 amino acids compared with 317 for NL-3 D. The first 114 predicted amino acids of the NL-3 K P1 region were 98% identical with RU1. The remaining 301 amino acids of the protein shared only 34% identity with RU1 but were 98% identical with NL-3 D. Primers were designed that flanked the recombination point in the P1 coding sequence of NL-3 K. An amplicon of the expected size was produced by reverse-transcriptase polymerase chain reaction of total nucleic acid extracts of bean plants inoculated with NL-3 K, but not from those with NL-3 D or RU1. The increased symptom severity on selected common bean lines induced by NL-3 K suggests that the P1 gene may play a significant role in pathogenicity and virulence.
