Molecular Taxonomical Study of the Species Genus Phalaris L. from the Gramineae Family in Iraq.

Abstract

The study was carried out to investigate molecular phylogenetic relationships for five species from the genus "phalaris" in Iraq by using sequencing technique of the Chloroplast gene maturase K (MatK).The results of genetic dendrogram showed a cluster analysis of species and descend of P.arundinacea alone in a single clade in the base of genetic dendrogram which consider as a sister clade to the p.paradoxa clade .While The three other species P.coerulescens , P.brachysta and P.minor were included in one main clade and distributed in a secondary subclade . The P.coerulescens is descended in a single clade in the base of the secondary main clade and considered as a secondary clade that collecting P.brachysta & P.minor. The results showed reliability of sequencing Matk gene which used to separate genus species from each other . While, close relationship in some species indicates that this species belong to one genus . Generally this molecular study confirmed the strong relationship among species that share the same genus Phalaris in Iraq in one common ancestor.
