Determination of Genetic Diversity of Some Species of Brassicaceae Using SDS-PAGE of Seed Protein and ISSR Markers

Document Type : Regular issue (Original Article)

Abstract

EVALUATION of genetic diversity among 10 species of Brassicaceae have been performed based on variations in seed protein electrophoretic patterns as revealed by SDS-PAGE and ISSR analyses, separately and in combination. The maximum genetic similarity was observed between <i>Brassica nigra</i> and<i> B. rapa,</i> while the lowest genetic similarity was observed between <i> B. nigra </i>and <i>Sisymbrium irrio.</i> Cluster analysis generated a dendrogram that separated the studied taxa in two main clusters; the five species of tribe Brassiceae were grouped close to each other in one cluster with <i>Sisymbrium irrio. </i>The remaining studied species;<i> Capsella bursapastoris, Erysimum cheiranthoides, Mathiola longipetale and Thlaspi arvense,</i> were grouped in a second cluster.
