[SGP polymorphism in cultivated naked barley from Qinghai-Tibet plateau in China and the relationship between SGPs and starch content].
Starch granule proteins (SGPs) are minor components bound with starch granule, which mutation may be related to starch properties. This study investigated the variation of SGPs in cultivated naked barley from Qinghai-Tibet Plateau in China for the first time, and the relationship between SGPs and starch content was preliminarily done. Ten major SGPs and 16 types of patterns were present in 66 cultivated naked varieties, indicating SGPs in cultivated naked barley from Qinghai-Tibet Plateau in China are polymorphic. SGPs in Tibet and Sichuan naked barley were greatly different and SGPs were specific to origin of site. Significance test analysis demonstrates SGPs described in this study except for SGP1 may be related with the variation of starch content in different naked barley.
