Analysis of sequence data from the chloroplast gene ndhF identifies at least 12 major well-supported clades within the genus Solanum. These are briefly described, given informal clade names, and compared with the groups recognized by previous Solanum workers. Non-molecular synapomorphies are proposed for many of the clades. Continued use of informal taxonomic designations is advocated for new i...

The basidiomycete genus Galerina Earle accommodates more than 300 small brown-spored agarics worldwide, predominantly described from the Northern hemisphere. The delimitation of species and infrageneric units hitherto has been based on morphological and, to some extent, ecological characters. In this study we have analyzed nuclear ribosomal LSU and ITS sequences to reveal infrageneric phylogeny...

The genus Dalbergia has a pantropical distribution and comprises approximately 250 species. Previous phylogenetic studies on the revealed that is monophyletic sister to Machaerium Aeschynomene sect. Ochopodium. However, due limited samples or DNA regions in these studies, relationships among major clades are still unresolved, divergence dates biogeographical history of have not been addressed. ...

In Malpighiaceae, Hiptage represents one of the seven past dispersal events from Neotropics to Paleotropical region, being by far most widely diversified and distributed genus Malpighiaceae. this study, we tested current infrageneric classification with a dated calibrated molecular phylogeny. We also reconstructed ancestral areas elucidate which route led colonization southeast Asia recent comm...

Crotalaria (Fabaceae) is the largest legume genus represented by 81 species in India. The existing sectional classification for Crotalaria in India is based on morphological characters and is not completely supported by the molecular phylogenetic studies. Molecular systematic studies of the Indian sections Crotalaria and Calycinae have enabled merging of both these sections into Calycinae. Trif...

Understanding the diversification of polyploid crops in the circum-Mediterranean region is a challenging issue in evolutionary biology. Sequence data of three nuclear genes and three plastid DNA fragments from 109 accessions of Avena L. (Poaceae) and the outgroups were used for maximum likelihood and Bayesian analyses. The evolution of cultivated oat (Avena sativa L.) and its close relatives wa...
