Abstract
Model species continue to underpin groundbreaking plant science research. At the same time, the phylogenetic resolution of the land plant tree of life continues to improve. The intersection of these 2 research paths creates a unique opportunity to further extend the usefulness of model species across larger taxonomic groups. Here we promote the utility of the Arabidopsis thaliana model species, especially the ability to connect its genetic and functional resources, to species across the entire Brassicales order. We focus on the utility of using genomics and phylogenomics to bridge the evolution and diversification of several traits across the Brassicales to the resources in Arabidopsis, thereby extending scope from a model species by establishing a "model clade." These Brassicales-wide traits are discussed in the context of both the model species Arabidopsis and the family Brassicaceae. We promote the utility of such a "model clade" and make suggestions for building global networks to support future studies in the model order Brassicales.

Zhang G, Ma H. Nuclear phylogenomics of angiosperms and insights into their relationships and evolution. JOURNAL OF INTEGRATIVE PLANT BIOLOGY 2024; 66:546-578. [PMID: 38289011 DOI: 10.1111/jipb.13609] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/21/2023] [Accepted: 01/03/2024] [Indexed: 02/06/2024]
Abstract
Angiosperms (flowering plants) are by far the most diverse land plant group with over 300,000 species. The sudden appearance of diverse angiosperms in the fossil record was referred to by Darwin as the "abominable mystery," hence contributing to the heightened interest in angiosperm evolution. Angiosperms display wide ranges of morphological, physiological, and ecological characters, some of which have probably influenced their species richness. The evolutionary analyses of these characteristics help to address questions of angiosperm diversification and require well resolved phylogeny. Following the great successes of phylogenetic analyses using plastid sequences, dozens to thousands of nuclear genes from next-generation sequencing have been used in angiosperm phylogenomic analyses, providing well resolved phylogenies and new insights into the evolution of angiosperms. In this review we focus on recent nuclear phylogenomic analyses of large angiosperm clades, orders, families, and subdivisions of some families and provide a summarized Nuclear Phylogenetic Tree of Angiosperm Families. The newly established nuclear phylogenetic relationships are highlighted and compared with previous phylogenetic results. The sequenced genomes of Amborella, Nymphaea, Chloranthus, Ceratophyllum, and species of monocots, Magnoliids, and basal eudicots, have facilitated the phylogenomics of relationships among five major angiosperms clades. All but one of the 64 angiosperm orders were included in nuclear phylogenomics with well resolved relationships except the placements of several orders. Most families have been included with robust and highly supported placements, especially for relationships within several large and important orders and families. Additionally, we examine the divergence time estimation and biogeographic analyses of angiosperm on the basis of the nuclear phylogenomic frameworks and discuss the differences compared with previous analyses. Furthermore, we discuss the implications of nuclear phylogenomic analyses on ancestral reconstruction of morphological, physiological, and ecological characters of angiosperm groups, limitations of current nuclear phylogenomic studies, and the taxa that require future attention.

Foliar endophyte diversity in Eastern Asian-Eastern North American disjunct tree species - influences of host identity, environment, phylogeny, and geographic isolation. FRONTIERS IN PLANT SCIENCE 2023; 14:1274746. [PMID: 38192694 PMCID: PMC10773735 DOI: 10.3389/fpls.2023.1274746] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Accepted: 10/27/2023] [Indexed: 01/10/2024]
Abstract
Introduction The well-known eastern Asian (EA) and eastern North American (ENA) floristic disjunction provides a unique system for biogeographic and evolutionary studies. Despite considerable interest in the disjunction, few studies have investigated the patterns and their underlying drivers of allopatric divergence in sister species or lineages isolated in the two areas. Endophyte diversity and assembly in disjunct sister taxa, as an ecological trait, may have played an important role in the processes of allopatric evolution, but no studies have examined endophytes in these lineages. Here we compared foliar endophytic fungi and bacteria-archaea (FEF and FEB) in 17 EA-ENA disjunct species or clade pairs from genera representing conifers and 10 orders of five major groups of angiosperms and 23 species of Cornus from EA and North America. Methods Metagenomic sequencing of fungal ITS and bacterial-archaeal 16S rDNA was used to capture the foliar endophytic communities. Alpha and beta diversity of fungi and bacteria were compared at multiple scales and dimensions to gain insights into the relative roles of historical geographic isolation, host identity, phylogeny, and environment from samples at different sites in shaping endophytic diversity patterns. Results We found that beta diversity of endophytes varied greatly among plant individuals within species and between species among genera at the same sampling site, and among three sampling sites, but little variation between region-of-origin of all plant species (EA vs ENA) and between EA-ENA disjunct counterparts within genera. Various numbers of indicator fungal species differing in abundance were identified for each plant genus and Cornus species. An overall significant correlation between endophyte community dissimilarity and phylogenetic distance of plants was detected among the disjunct genera but not among species of Cornus. However, significant correlations between beta diversities at different taxonomic scales of endophytes and phylogenetic distances of Cornus species were observed. Discussion Our results suggest important roles of host identity and environment (sampling sites), and a likely minor role of phylogenetic divergence and historical biogeographic isolation in shaping the pattern of foliar endophyte diversity and assembly in the EA-ENA disjunct genera and Cornus. The results lead to a hypothesis that the sister taxa in EA and ENA likely differ in FEF and FEB when growing in native habitats due to differences in local environments, which may potentially drive allopatric divergence of the functional features of species.

Abstract
Some of the most vexing problems of deep level relationship that remain in angiosperms involve the superrosids. The superrosid clade contains a quarter of all angiosperm species, with 18 orders in three subclades (Vitales, Saxifragales and core rosids) exhibiting remarkable morphological and ecological diversity. To help resolve deep-level relationships, we constructed a high-quality chromosome-level genome assembly for Tiarella polyphylla (Saxifragaceae) thus providing broader genomic representation of Saxifragales. Whole genome microsynteny analysis of superrosids showed that Saxifragales shared more synteny clusters with core rosids than Vitales, further supporting Saxifragales as more closely related with core rosids. To resolve the ordinal phylogeny of superrosids, we screened 122 single copy nuclear genes from genomes of 36 species, representing all 18 superrosid orders. Vitales were recovered as sister to all other superrosids (Saxifragales + core rosids). Our data suggest dramatic differences in relationships compared to earlier studies within core rosids. Fabids should be restricted to the nitrogen-fixing clade, while Picramniales, the Celastrales-Malpighiales (CM) clade, Huerteales, Oxalidales, Sapindales, Malvales and Brassicales formed an "expanded" malvid clade. The Celastrales-Oxalidales-Malpighiales (COM) clade (sensu APG IV) was not monophyletic. Crossosomatales, Geraniales, Myrtales and Zygophyllales did not belong to either of our well-supported malvids or fabids. There is strong discordance between nuclear and plastid phylogenetic hypotheses for superrosid relationships; we show that this is best explained by a combination of incomplete lineage sorting and ancient reticulation.

AMERICAN JOURNAL OF BOTANY 2023; 110:e16116. [PMID: 36480351 DOI: 10.1002/ajb2.16116] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/12/2022] [Revised: 11/29/2022] [Accepted: 11/29/2022] [Indexed: 06/17/2023]
Abstract
PREMISE A major goal of systematic biology is to uncover the evolutionary history of organisms and translate that knowledge into stable classification systems. Here, we integrate three sets of genome-wide data to resolve phylogenetic relationships in Cornaceae (containing only Cornus s.l.), reconstruct the biogeographic history of the clade, and provide a revised classification using the PhyloCode to stabilize names for this taxonomically controversial group. METHODS We conducted phylogenetic analyses using 312 single-copy nuclear genes and 70 plastid genes from Angiosperms353 Hyb-Seq, plus numerous loci from RAD-Seq. We integrated fossils using morphological data and produced a dated phylogeny for biogeographical analysis. RESULTS A well-resolved, strongly supported, comprehensive phylogeny was obtained. Biogeographic analyses support an origin and rapid diversification of Cornus into four morphologically distinct major clades in the Northern Hemisphere (with an eastern Asian ancestor) during the late Cretaceous. Dispersal into Africa from eastern Asia likely occurred along the Tethys Seaway during the Paleogene, whereas dispersal into South America likely occurred during the Neogene. Diversification within the northern hemisphere likely involved repeated independent colonization of new areas during the Paleogene and Neogene along the Bering Land Bridge, the North Atlantic Land Bridge, and the Tethys Seaway. Thirteen strongly supported clades were named following rules of the PhyloCode. CONCLUSIONS Our study provides an example of integrating genomic and morphological data to produce a robust, explicit species phylogeny that includes fossil taxa, which we translate into an updated classification scheme using the PhyloCode to stabilize names.

Abstract
Understanding the genetic changes associated with the evolution of biological diversity is of fundamental interest to molecular ecologists. The assessment of genetic variation at hundreds or thousands of unlinked genetic loci forms a sound basis to address questions ranging from micro- to macroevolutionary timescales, and is now possible thanks to advances in sequencing technology. Major difficulties are associated with (i) the lack of genomic resources for many taxa, especially from tropical biodiversity hotspots; (ii) scaling the numbers of individuals analysed and loci sequenced; and (iii) building tools for reproducible bioinformatic analyses of such data sets. To address these challenges, we developed target capture probes for genomic studies of the highly diverse, pantropically distributed and economically significant rosewoods (Dalbergia spp.), explored the performance of an overlapping probe set for target capture across the legume family (Fabaceae), and built the general purpose bioinformatic pipeline CaptureAl. Phylogenomic analyses of Malagasy Dalbergia species yielded highly resolved and well supported hypotheses of evolutionary relationships. Population genomic analyses identified differences between closely related species and revealed the existence of a potentially new species, suggesting that the diversity of Malagasy Dalbergia species has been underestimated. Analyses at the family level corroborated previous findings by the recovery of monophyletic subfamilies and many well-known clades, as well as high levels of gene tree discordance, especially near the root of the family. The new genomic and bioinformatic resources, including the Fabaceae1005 and Dalbergia2396 probe sets, will hopefully advance systematics and ecological genetics research in legumes, and promote conservation of the highly diverse and endangered Dalbergia rosewoods.

Abstract
The fruit morphological structures of the Cornaceae of China and related taxa were studied using the wax GMA semi-thin section method and other methods to identify characters useful in delimiting clades circumscribed in previous molecular phylogenetic studies. Maximum parsimony analyses of 27 fruit structural characters resulted in a generally poorly resolved strict consensus tree, yet one whose major clades matched those revealed previously. Cornaceae of China and related taxa are recognized in four significant clades with the following fruit structural features: (1) Helwingia, fruits lack trichome, the abdominal vascular bundles are close to the endocarp, and the endocarp sclereid is elongated; (2) Aucuba, single-cell lanceolate trichomes, pericarp without secretory structure; (3) Torricellia, polygon and elongated sclereids in the endocarp, pericarp without crystal and tannin; and (4) Cornus sensu lato, the trichome is T-shaped, the abdominal ventral bundle is absent, and the endocarp sclereid is nearly round. In Cornus sensu lato, this document supported that the cornelian cherries (CC, subg. Cornus) and the big-bracted dogwoods (BB, subg. Syncarpea) are sister groups. The dwarf dogwoods (DW, subg. Arctocrania) are sister to them, and the blue- or white-fruited dogwoods (BW, subg. Kraniopsis, subg. Yinquania, and subg. Mesomora) are the base of the Cornus sensu lato clade. The number of cell layers of endocarps and the types of crystals afford sound evidence for identifying their relationship. This study indicated that the fruit structures of Cornaceae might provide morphological and anatomical evidence for molecular phylogeny.

Abstract
Convolvulaceae is a family of c. 2,000 species, distributed across 60 currently recognized genera. It includes species of high economic importance, such as the crop sweet potato (Ipomoea batatas L.), the ornamental morning glories (Ipomoea L.), bindweeds (Convolvulus L.), and dodders, the parasitic vines (Cuscuta L.). Earlier phylogenetic studies, based predominantly on chloroplast markers or a single nuclear region, have provided a framework for systematic studies of the family, but uncertainty remains at the level of the relationships among subfamilies, tribes, and genera, hindering evolutionary inferences and taxonomic advances. One of the enduring enigmas has been the relationship of Cuscuta to the rest of Convolvulaceae. Other examples of unresolved issues include the monophyly and relationships within Merremieae, the "bifid-style" clade (Dicranostyloideae), as well as the relative positions of Erycibe Roxb. and Cardiochlamyeae. In this study, we explore a large dataset of nuclear genes generated using Angiosperms353 kit, as a contribution to resolving some of these remaining phylogenetic uncertainties within Convolvulaceae. For the first time, a strongly supported backbone of the family is provided. Cuscuta is confirmed to belong within family Convolvulaceae. "Merremieae," in their former tribal circumscription, are recovered as non-monophyletic, with the unexpected placement of Distimake Raf. as sister to the clade that contains Ipomoeeae and Decalobanthus Ooststr., and Convolvuleae nested within the remaining "Merremieae." The monophyly of Dicranostyloideae, including Jacquemontia Choisy, is strongly supported, albeit novel relationships between genera are hypothesized, challenging the current tribal delimitation. The exact placements of Erycibe and Cuscuta remain uncertain, requiring further investigation. Our study explores the benefits and limitations of increasing sequence data in resolving higher-level relationships within Convolvulaceae, and highlights the need for expanded taxonomic sampling, to facilitate a much-needed revised classification of the family.

Effectiveness of Two Universal Angiosperm Probe Sets Tested In Silico for Caryophyllids Taxa with Emphasis on Cacti Species. Genes (Basel) 2022; 13:genes13040570. [PMID: 35456376 PMCID: PMC9032312 DOI: 10.3390/genes13040570] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2022] [Revised: 03/17/2022] [Accepted: 03/21/2022] [Indexed: 02/01/2023] Open
Abstract
In angiosperms, huge advances in massive DNA sequencing technologies have impacted phylogenetic studies. Probe sets have been developed with the purpose of recovering hundreds of orthologous loci of targeted DNA sequences (TDS) across different plant lineages. We tested in silico the effectiveness of two universal probe sets in the whole available genomes of Caryophyllids, emphasizing phylogenetic issues in cacti species. A total of 870 TDS (517 TDS from Angiosperm v.1 and 353 from Angiosperms353) were individually tested in nine cacti species and Amaranthus hypochondriacus (external group) with ≥17 Gbp of available DNA data. The effectiveness was measured by the total number of orthologous loci recovered and their length, the percentage of loci discarded by paralogy, and the proportion of informative sites (PIS) in the alignments. The results showed that, on average, Angiosperms353 was better than Angiosperm v.1 for cacti species, since the former obtained an average of 275.6 loci that represent 123,687 bp, 2.48% of paralogous loci, and 4.32% of PIS in alignments, whereas the latter recovered 148.4 loci (37,683 bp), 10.38% of paralogous loci, and 3.49% of PIS. We recommend the use of predesigned universal probe sets for Caryophyllids, since these recover a high number of orthologous loci that resolve phylogenetic relationships.

Abstract
Relationships within the major clades of Cactaceae are relatively well known based on DNA sequence data mostly from the chloroplast genome. Nevertheless, some nodes along the backbone of the phylogeny, and especially generic and species-level relationships, remain poorly resolved and are in need of more informative genetic markers. In this study, we propose a new approach to solve the relationships within Cactaceae, applying a targeted sequence capture pipeline. We designed a custom probe set for Cactaceae using MarkerMiner and complemented it with the Angiosperms353 probe set. We then tested both probe sets against 36 different transcriptomes using Hybpiper preferentially retaining phylogenetically informative loci and reconstructed the relationships using RAxML-NG and Astral. Finally, we tested each probe set through sequencing 96 accessions, representing 88 species across Cactaceae. Our preliminary analyses recovered a well-supported phylogeny across Cactaceae with a near identical topology among major clade relationships as that recovered with plastome data. As expected, however, we found incongruences in relationships when comparing our nuclear probe set results to plastome datasets, especially at the generic level. Our results reveal great potential for the combination of Cactaceae-specific and Angiosperm353 probe set application to improve phylogenetic resolution for Cactaceae and for other studies.

Resolving species boundaries in a recent radiation with the Angiosperms353 probe set: the Lomatium packardiae/L. anomalum clade of the L. triternatum (Apiaceae) complex. AMERICAN JOURNAL OF BOTANY 2021; 108:1217-1233.

Abstract
PREMISE Speciation not associated with morphological shifts is challenging to detect unless molecular data are employed. Using Sanger-sequencing approaches, the Lomatium packardiae/L. anomalum subcomplex within the larger Lomatium triternatum complex could not be resolved. Therefore, we attempt to resolve these boundaries here. METHODS The Angiosperms353 probe set was employed to resolve the ambiguity within Lomatium triternatum species complex using 48 accessions assigned to L. packardiae, L. anomalum, or L. triternatum. In addition to exon data, 54 nuclear introns were extracted and were complete for all samples. Three approaches were used to estimate evolutionary relationships and define species boundaries: STACEY, a Bayesian coalescent-based species tree analysis that takes incomplete lineage sorting into account; ASTRAL-III, another coalescent-based species tree analysis; and a concatenated approach using MrBayes. Climatic factors, morphological characters, and soil variables were measured and analyzed to provide additional support for recovered groups. RESULTS The STACEY analysis recovered three major clades and seven subclades, all of which are geographically structured, and some correspond to previously named taxa. No other analysis had full agreement between recovered clades and other parameters. Climatic niche and leaflet width and length provide some predictive ability for the major clades. CONCLUSIONS The results suggest that these groups are in the process of incipient speciation and incomplete lineage sorting has been a major barrier to resolving boundaries within this lineage previously. These results are hypothesized through sequencing of multiple loci and analyzing data using coalescent-based processes.

Zhou W, Soghigian J, Xiang QYJ. A New Pipeline for Removing Paralogs in Target Enrichment Data. Syst Biol 2021; 71:410-425. [PMID: 34146111 PMCID: PMC8974407 DOI: 10.1093/sysbio/syab044] [Citation(s) in RCA: 21] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/19/2021] [Revised: 06/04/2021] [Accepted: 06/12/2021] [Indexed: 12/30/2022] Open
Abstract
Target enrichment (such as Hyb-Seq) is a well-established high throughput sequencing
method that has been increasingly used for phylogenomic studies. Unfortunately, current
widely used pipelines for analysis of target enrichment data do not have a vigorous
procedure to remove paralogs in target enrichment data. In this study, we develop a
pipeline we call Putative Paralogs Detection (PPD) to better address putative paralogs
from enrichment data. The new pipeline is an add-on to the existing HybPiper pipeline, and
the entire pipeline applies criteria in both sequence similarity and heterozygous sites at
each locus in the identification of paralogs. Users may adjust the thresholds of sequence
identity and heterozygous sites to identify and remove paralogs according to the level of
phylogenetic divergence of their group of interest. The new pipeline also removes highly
polymorphic sites attributed to errors in sequence assembly and gappy regions in the
alignment. We demonstrated the value of the new pipeline using empirical data generated
from Hyb-Seq and the Angiosperms353 kit for two woody genera Castanea
(Fagaceae, Fagales) and Hamamelis (Hamamelidaceae, Saxifragales).
Comparisons of data sets showed that the PPD identified many more putative paralogs than
the popular method HybPiper. Comparisons of tree topologies and divergence times showed
evident differences between data from HybPiper and data from our new PPD pipeline. We
further evaluated the accuracy and error rates of PPD by BLAST mapping of putative
paralogous and orthologous sequences to a reference genome sequence of Castanea
mollissima. Compared to HybPiper alone, PPD identified substantially more
paralogous gene sequences that mapped to multiple regions of the reference genome (31
genes for PPD compared with 4 genes for HybPiper alone). In conjunction with HybPiper,
paralogous genes identified by both pipelines can be removed resulting in the construction
of more robust orthologous gene data sets for phylogenomic and divergence time analyses.
Our study demonstrates the value of Hyb-Seq with data derived from the Angiosperms353
probe set for elucidating species relationships within a genus, and argues for the
importance of additional steps to filter paralogous genes and poorly aligned regions
(e.g., as occur through assembly errors), such as our new PPD pipeline described in this
study. [Angiosperms353; Castanea; divergence time;
