The inverted repeat-lacking clade (IRLC) is one of the most derived clades within the subfamily Papilionoideae of the legume family, and includes various economically important plants, e.g., chickpeas, peas, liquorice, and the largest genus of angiosperms, Astragalus. Tribe Wisterieae is one of the earliest diverged groups of the IRLC, and its generic delimitation and spatiotemporal diversification needs further clarifications. Based on genome skimming data, we herein reconstruct the phylogenomic framework of the IRLC, and infer the inter-generic relationships and historical biogeography of Wisterieae. We redefine tribe Caraganeae to contain Caragana only, and tribe Astragaleae is reduced to the Erophaca-Astragalean clade. The chloroplast capture scenario was hypothesized as the most plausible explanation of the topological incongruences between the chloroplast CDSs and nuclear ribosomal DNA trees in both the Glycyrrhizinae-Adinobotrys-Wisterieae clade and the Chesneyeae-Caraganeae-Hedysareae clade. A new name, Caragana lidou L. Duan & Z.Y. Chang, is proposed within Caraganeae. Thirteen genera are herein supported within Wisterieae, including a new genus, Villosocallerya L. Duan, J. Compton & Schrire, segregated from Callerya. Our biogeographic analyses suggest that Wisterieae originated in the late Eocene and its most recent common ancestor (MRCA) was distributed in continental southeastern Asia. Lineages of Wisterieae remained in the ancestral area from the early Oligocene to the early Miocene. By the middle Miocene, Whitfordiodendron and the MRCA of Callerya-Kanburia-Villosocallerya Clade became disjunct between the Sunda area and continental southeastern Asia, respectively; the MRCA of Wisteria migrated to North America via the Bering land bridge. The ancestor of Austrocallerya and Padbruggea migrated to the Wallacea-Oceania area, which split in the early Pliocene. In the Pleistocene, Wisteria brachybotrys, W. floribunda and Wisteriopsis japonica reached Japan, and Callerya cinerea dispersed to South Asia. This study provides a solid phylogenomic for further evolutionary/biogeographic/systematic investigations on the ecologically diverse and economically important IRLC legumes.

Taxonomic Notes on the 'Mahat' ( and , Moraceae) Species Complex in Thailand.

Plants (Basel) 2020 Mar 22;9(3). Epub 2020 Mar 22.

Department of Pharmacognosy, Faculty of Pharmacy, Mahidol University, Bangkok 10400, Thailand.

'Mahat' is a well-known medicinal plant utilized in Thailand. The Thai name 'Mahat' has been used in many scientific articles for years. However, it is, unpredictably, a homonym of two scientific names in Flora of Thailand, i.e., and . Additionally, both species are complex due to their high morphological variation. This causes difficulties in species identification especially when this Thai name is referred to as the scientific name for research publication, quality control of pharmaceutical raw materials, and registration of pharmaceutical products. In this study, we scrutinized the taxonomy of 'Mahat' by detailed examination of its morphology and distribution, including molecular and qualitative phytochemical studies. Leaf surfaces were inspected using scanning electron microscopy. The phylogeny of both species was studied using DNA sequences of nuclear and plastid regions. Chromatographic fingerprints, focusing on the major active compound oxyresveratrol, were identified using high-performance liquid chromatography. According to our current study, phylogenetic evidence showed that some samples of both species were clustered together in the same clade and phytochemical fingerprints were almost identical. These results are valuable data for taxonomic revision in the near future and reveal the possible utilization of as a new material source of oxyresveratrol in the pharmaceutical industry.

The Group redefined and Tribe Wisterieae (Fabaceae) emended based on morphology and data from nuclear and chloroplast DNA sequences.

PhytoKeys 2019 26;125:1-112. Epub 2019 Jun 26.

Silpakorn University, Department of Biology, Faculty of Science, Sanam Chandra Palace campus, Nakhon Pathom 73000, Thailand Silpakorn University Nakhon Pathom Thailand.

The Tribe Wisterieae (Zhu 1994), founded on the single genus , is emended and recircumscribed based on morphology and data from nuclear ITS and , and chloroplast DNA sequences. This newly enlarged tribe comprises 36 species and 9 infraspecific taxa within 13 described genera. Six genera are new, two are reinstated and five were previously placed in Tribe Millettieae. The genus is also reinstated comprising two species including the new combination . Other reinstated genera include , with four species, and , with three species, including the reinstatement of and the new combination P.filipesvar.tomentosa. The existing genera , , (with the new combination E.racemosavar.pallida), and , with the new combinations W.frutescenssubsp.macrostachya are evaluated. The new genera comprise three Australasian species in : , and ; with five species from east Asia has six new combinations: , and W.reticulatavar.stenophylla. Two species comprise the new Thai genus : and . comprises the two species: and and the monotypic genera and are based respectively on the species and . Lectotypes are designated for the names , , , , M.reticulatavar.stenophylla, , , , , and . A neotype is designated for the name .

Phylogeny of palaeotropic Derris-like taxa (Fabaceae) based on chloroplast and nuclear DNA sequences shows reorganization of (infra)generic classifications is needed.

Am J Bot 2012 Nov;99(11):1793-808

Naturalis Biodiversity Center (section NHN), Leiden University, P. O. Box 9514, 2300 RA Leiden, The Netherlands.

Premise Of The Study: Palaeotropic Derris-like taxa (family Fabaceae, tribe Millettieae) comprise 6-9 genera. They are well known as important sources of rotenone toxin, which are used as organic insecticide and fish poison. However, their phylogenetic relationships and classification are still problematic due to insufficient sampling and high morphological variability.

Methods: Fifty species of palaeotropic Derris-like taxa were sampled, which is more than in former studies. Three chloroplast genes (trnK-matK, trnL-F IGS, and psbA-trnH IGS) and nuclear ribosomal ITS /5.8S were analyzed using parsimony and Bayesian methods.

Key Results: Parsimony and Bayesian analyses of individual and combined markers show more or less similar tree topologies (only varying in terminal branches). The old-world monophyletic genera Aganope, Brachypterum, and Leptoderris are distinct from Derris s.s., and their generic status is here confirmed. Aganope may be classified into two or three subgeneric taxa. Paraderris has to be included in Derris s.s. to form a monophyletic group. The genera Philenoptera, Deguelia, and Lonchocarpus are monophyletic and distinct from each other and clearly separate from Derris s.s. Morphologically highly similar species of Derris s.s. are shown to be unrelated. Our study shows that previous infrageneric classifications of Derris are incorrect. Paraderris elliptica may contain several cryptic lineages that need further investigation.

Conclusions: The concept of the genus Derris s.s. should be reorganized with a new generic circumscription by including Paraderris but excluding Brachypterum. Synapomorphic morphological features will be examined in future studies, and the status of the newly defined Derris and its closely related taxa will be formalized.
