Phylogenetic Study of the Genus Cyperus L. (Cyperaceae) based on Chloroplast Maturase K (Matk ) Gene in Iraq.

Abstract

This study was conducted to investigate the complete sequences of chloroplast maturase K (matK ) gene, the study were determined for five species of Cyperus L. Cyperaceae in Iraq to infer phylogenetic relationships . Dipsacus laciniatus were used as out groups.. The phylogenetic tree based on Maximum Parsimony (MP) included three major clades the first major clade included C.alternifolius in the base of trees which is a sister clade to C.iria , was the third major clade gathered the C.aucheri, C.rotandus, and C.longus respectively with C.iria . These clades are subdivided into two secondary clades, C.aucheri descendent in single clade alone with the C.rotandus and C.longus . the clades of Bayesian analysis are as follow: First Major clade includes consist only C.alternifolius with the Second Major clade C.aucheri and the last Major clades subdivided into two subclades the first on descending C.iria  alone as a sister clade with C.longus and C.rotandus subclade .
