摘要

Starch granule proteins (SGPs) are minor components bound with starch granule, whose variation could impact starch properties. This study investigated, for the first time, the variation of SGPs in the cultivated naked barley from Qinghai-Tibet Plateau in China. The relation-ship between SGPs and starch content was preliminarily dealt with. Ten major SGPs and 16 types of patterns were present in the 66 cultivated naked varieties, indicating that the SGPs in cultivated naked barley from Qinghai-Tibet Plateau in China are polymorphic. The SGPs of naked barley in Tibet and Sichuan were greatly different and the SGP patterns were specific to sampling regions. Significance test analysis demonstrated that the SGPs described in this study, except for SGP1, could be related with the variation of starch content in the different naked barleys.
