The genus Crocus L. of Iridaceae family contains about 160 species and is considered as a complex group plant taxa with regard to evolutionary phylogenetic events. Inter-specific hybridization gene flow contribute genetic homogeneity in one hand high within variability content overlaps caused resolution problem. In spite extensive molecular studies this genus, nothing known DNA sequences or Sin...

The Commelinaceae are a pantropical family of monocotyledonous herbs. Previous phylogenies in Commelinaceae have emphasized sampling among genera. We extended this previous work by sampling multiple species within some of the largest genera of Commelinaceae (especially Commelina and Tradescantia , and also including Callisia , Cyanotis, Gibasis, and Murdannia ), and by sequencing noncoding regi...

Variability within eight cpDNA introns including trnS-trnfM, trnL-trnT, trnH-psbA, trnF-trnL, trnD-trnT, trnCrpoB, rps16 and matK, and the nuclear waxy introns was examined in seven species of Capsicum (C. annuum, C. baccatum, C. chinense, C. frutescens, C. pubescens, C. chacoense and C. rhomboideum) in order to evaluate the feasibility of utilizing these loci for DNA barcoding within the C. an...

The coding region of the mat K gene and two intergenic spacers, psb A-trn H and trn L(UAA)-trn F(GAA), of cpDNA were sequenced to study phylogenetic relationships of 32 Paeonia species. In the psb A-trn H intergenic spacer, short sequences bordered by long inverted repeats have undergone inversions that are often homoplasious mutations. Insertions/deletions found in the two intergenic spacers, ...

Plastid DNA sequences evolve slowly in palms but show that the family is monophyletic and highly divergent relative to other major monocot clades. It is therefore difficult to place the root within the palms because faster evolving, length-variable sequences cannot be aligned with outgroup monocots, and length-conserved regions have been thought to give too few characters to resolve basal nodes...
