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.
Historical climate change and speciation: neotropical seasonally dry forest plants show patterns of both tertiary and quaternary diversification.
Evolutionary rate analysis of sequence data of nuclear ribosomal internal transcribed spacers in diverse taxa occupying neotropical seasonally dry forests indicates plausibility both for models that predict tropical species diversity to be recent and that invoke a role for Pleistocene climatic change.
Woody Plant Diversity, Evolution, and Ecology in the Tropics: Perspectives from Seasonally Dry Tropical Forests
It is argued that this is evidence that the SDTF is a metacommunity (biome) for woody plant clades, and that phylogenetic, population genetic, biogeographic, and community ecological patterns differ in woody plants from tropical rain forests and savannas.
The dalbergioid legumes (Fabaceae): delimitation of a pantropical monophyletic clade.
A monophyletic pantropical group of papilionoid legumes is circumscribed to include all genera previously referred to the tribes Aeschynomeneae and Adesmieae, the subtribe Bryinae of the Desmodieae, and tribe Dalbergieae except Andira, Hymenolobium, Vatairea, and Vatairesopsis.
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.
Phylogeny of the Genus Phaseolus (Leguminosae): A Recent Diversification in an Ancient Landscape
A combined parsimony analysis of the species of Phaseolus and closely related New World genera was performed with sequences from the nuclear ribosomal ITS/5.8 S and plastid trnK loci, suggesting the maximum age estimate of a Late Pliocene to Pleistocene diversification ofphaseolus post-dates the major tectonic activity in Mexico.
Origins and relationships of tropical North America in the context of the boreotropics hypothesis.
These findings are consistent with the boreotropics hypothesis, and additional evidence suggests that many tropical elements in North America could be descendants of northern tropical progenitors.
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.
Evolutionary islands in the Andes: persistence and isolation explain high endemism in Andean dry tropical forests
Aim  The tropical Andes are a world biodiversity hotspot. With diverse biomes and dramatic, geologically recent mountain uplift, they offer a system to study the relative contributions of geological
