Biosystematic study of Phalaris L. species (Poaceae) in Iran

Abstract

This study dealt with banding patterns of seed storage proteins using sodium dodecylsulphate-polyacrylamide gel electrophoresis (SDS-PAGE) with extract of bulked seeds of Phalaris L. species of Iran. The results showed that two varieties of P. paradoxa L. as var. praemorsa and var. paradoxa L. were closely related. A close relationship and high protein similarity (J=0.583) were found between P. arundinacea L. and P. brachystachys Link.. Electophoretic results were compared with previous anatomical and morphological studies. Key words: Phalaris, Taxon relationships, SDS-PAGE
