Phylogenetic systematics of the tribe Millettieae (Leguminosae) based on chloroplast trnK/matK sequences and its implications for evolutionary patterns in Papilionoideae.

چکیده
Phylogenetic relationships in the tribe Millettieae and allies in the subfamily Papilionoideae (Leguminosae) were reconstructed from chloroplast trnK/matK sequences. Sixty-two accessions representing 57 traditionally recognized genera of Papilionoideae were sampled, including 27 samples from Millettieae. Phylogenies were constructed using maximum parsimony and are well resolved and supported by high bootstrap values. A well-supported "core Millettieae" clade is recognized, comprising the four large genera Millettia, Lonchocarpus, Derris, and Tephrosia. Several other small genera of Millettieae are not in the core Millettieae clade. Platycyamus is grouped with Phaseoleae (in part). Ostryocarpus, Austrosteenisia, and Dalbergiella are neither in the core Millettieae or Phaseoleae clade. These taxa, along with core Millettieae and Phaseoleae, form a monophyletic sister group to Indigofereae. Cyclolobium and Poecilanthe are close to Brongniartieae. Callerya and Wisteria belong to a large clade that includes all the legumes that lack the inverted repeat in their chloroplast genome, which confirms previous rbcL and phytochrome gene family phylogenies. The evolutionary history of four characters was examined in Millettieae and allies: the presence of canavanine, inflorescence types, the dehiscence of pods, and the presence of winged pods. trnK/matK sequence analysis suggests that the presence of a pseudoraceme or pseudopanicle and the accumulation of nonprotein amino acids are phylogenetically informative for Millettieae and allies with only a few exceptions.

Phylogenetic analysis of 330 plastid matK gene sequences, representing 235 genera from 37 of 39 tribes, and four outgroup taxa from eurosids I supports many well-resolved subclades within the Leguminosae. These results are generally consistent with those derived from other plastid sequence data (rbcL and trnL), but show greater resolution and clade support overall. In particular, the monophyly ...

متن کاملA phylogenetic analysis of the Cucurbitaceae: evidences from matk nucleotide sequences
MaturaseK gene (matK) of chloroplast is highly conserved in plant systematics which is involved in Group-II intron splicing. The size of the gene is approximately 1500 base pairs in length, located with in the intron of trnK. In the present study, matK gene from Cucurbitaceae was taken for the analysis of variants, parsimony site, patterns, transition/ transversion rate and phylogeny. The famil...

The chloroplast gene matK, located in the intron of chloroplast trnK, encodes maturase, and variations of matK provide substantial resolution for phylogenetic analyses at intergeneric levels. Sequence data from 127 species (including subspecies and varieties) of Brassicaceae and one outgroup specie (Cleome gynandra) were used to construct the phylogeny of this family and elucidate the phylogene...
