Evolutionary and demographic history among Maghrebian Medicago species (Fabaceae) based on the nucleotide sequences of the chloroplast DNA barcode trnH-psbA
چکیده انگلیسی
Data from trnH-psbA intergenic spacer (cpDNA) were analyzed to elucidate molecular evolution within and among Maghrebian species of Medicago. The spacer highlighted a high interspecific variation and a low intraspecific diversity among species. Haplotype and nucleotide diversities revealed high level of variation. Parsimony and median-joining Network methods revealed (1) the segregation into 17 haplotypes; (2) the ancestral behaviour of the annual Medicago minima and (3) the clusters are independent of the geographic origin. The neutral evolution of Wright and Fisher is rejected since the Tajima's D values deviated from 0. Besides, the statistical analyses are in agreement with an evolution into stable populations' size.
