using protein markers of embryo and seed storage proteins in identification of four pistachio cultivars

Identification of protein marker for Pistachio cultivars, as a valuable source of food is important. In this study, the protein patterns of embryo from four pistachio cultivars including Akbari, Ahmad Aghaei, Fandoghi and Kaleghouchi were analyzed using SDS-PAGE. The presence of protein bands about 90 and 45 killo dalton (kd) in protein pattern of embryonic axes in cultivars Kaleghouchi and Akbari respectively and the absence of protein bands with approximate molecular weight 30 and 20 kd in protein pattern of cotyledons in cultivars Kaleghouchi and Akbari respectively can be used as protein markers for these pistachio cultivars. On the other hand, the maximum expression level of bands 45 kd in protein pattern of cotyledons could be indicative of a protein marker for cultivar Ahmad Aghaei.
