Evolutionary rates analysis of Leguminosae implicates a rapid diversification of lineages during the tertiary.
Tertiary macrofossils of the flowering plant family Leguminosae were used as time constraints to estimate ages of the earliest branching clades identified in separate plastid matK and rbcL gene phylogenies, pointing to a rapid family-wide diversification, and predict few if any legume fossils prior to the Cenozoic.
A phylogeny of legumes (Leguminosae) based on analysis of the plastid matK gene resolves many well-supported subclades within the family.
Analysis of the matK data consistently resolves but modestly supports a clade comprising papilionoid taxa that accumulate canavanine in the seeds, which suggests a single origin for the biosynthesis of this most commonly produced of the nonprotein amino acids in legumes.
The its Region of Nuclear Ribosomal DNA: A Valuable Source of Evidence on Angiosperm Phylogeny
The internal transcribed spacer (ITS) region of 18S-26S nuclear ribosomal DNA (nrDNA) has proven to be a useful source of characters for phylogenetic studies in many angiosperm families. The two
Persistent nuclear ribosomal DNA sequence polymorphism in the Amelanchier agamic complex (Rosaceae).
Individual plants of several Amelanchier taxa contain many polymorphic nucleotide sites in the internal transcribed spacers (ITS) of nuclear ribosomal DNA (nrDNA). This polymorphism is unusual
Evidence on the monophyly of Astragalus (Fabaceae) and its major subgroups based on nuclear ribosomal DNA ITS and chloroplast DNA trnL intron data
Preliminary estimates of the absolute rate of species diversification in Astragalus suggest it may be higher than in some other, often cited, continental or insular adaptive radiations in angiosperms.
A new subfamily classification of the leguminosae based on a taxonomically comprehensive phylogeny
The classification of the legume family proposed here addresses the long-known non-monophyly of the traditionally recognised subfamily Caesalpinioideae, by recognising six robustly supported monophyletic subfamilies and reflects the phylogenetic structure that is consistently resolved.
Error, bias, and long-branch attraction in data for two chloroplast photosystem genes in seed plants.
Sequences of two chloroplast photosystem genes, psaA and psbB, together comprising about 3,500 bp, were obtained for all five major groups of extant seed plants and several outgroups among other vascular plants, and phylogenetic signals were obtained in parsimony analyses from partitions of the data into first and second codon positions versus third positions.
Phylogenetic systematics of the tribe Millettieae (Leguminosae) based on chloroplast trnK/matK sequences and its implications for evolutionary patterns in Papilionoideae.
Phylogenetic relationships in the tribe Millettieae and allies in the subfamily Papilionoideae (Leguminosae) were reconstructed from chloroplast trnK/matK sequences, suggesting that the presence of a pseudoraceme or pseudopanicle and the accumulation of nonprotein amino acids are phylogenetically informative for Milletties and allies with only a few exceptions.
