| Popis: | In this study reserve endosperm proteins, hordeins of seven spring barley cultivars with different origin: Zernogradskii (Russia), Bodega, Fink, Scarlett and Barke (Germany), Josefin and Astoria (France) were fractionated and characterized by SDS-PAGE electrophoresis. On the basis of the obtained spectra 19 bands (D + C + B) with different relative electrophoretic mobility and intensity were identified. The electrophoresis profiles of the groups D-, C- and B- hordein are designated as separate types (models) using the index corresponding to hordein blocks. We have established one profile type for D-hordein (D1), two- for C-hordein (C1, C2), and five – for B-hordein (B1, B2, B3, B4, B5). Based on these results hordein formulas (configurations) of accessions are constructed, which enable the expression of specific varietal characteristics and prove the existence of the inter allelic variation (hordein polymorphism) due to the presence or absence of protein components and their different electrophoretic mobility in the profiles of D-, C- and B-hordein. |
