花生属栽培种与野生种的蛋白质亚基构成分析

THE ANALYSIS OF CONSTITUENTS OF PROTEIN SUBUNITS FROM CULTI-SPECIES AND WILD SPECIES IN ARACHIS

蛋白质亚基构成分析表明:根据蛋白质亚基相似度指数,花生属(Arachis)栽培种的Virginia型同Peruvian型、Valencia型与Spanish型显示关系密切;同四倍体野生种山地花生表现亲缘;同花生组二倍体野生种A.cardenasii,A.baiizocoi,A.correntina和A.duranensis的关系,显然前二者较后二者更加相对亲近,但同外加脉组的绒毛黄果花生与三籽组的细小花生则为远缘。

The analysis of constituents of protein subunits by protein SDS-PAGE technique in 11 sp- ecies of Genus Arachis including 4 types of culti-species and 7 wild species showed that the band patterns may be divided into three sections, i.e. PⅠ, PⅡ and PⅢ presenting 5, 13 and 16 subunits respectively. The subunit number of diploid species was less than that of tetraploid species in general, but the difference of intraspecies or interspecies was mainly located in sec- tions PⅡ and PⅢ. According to the indices of similarity of protein subunits, the relationship among four types (Virginia, Peruvian, Valencia and Spanish) of tetraploid culti-species (Arachis hypogaea) seemed mostly close to each other and A. monticola. the tetraploid wild spccies was related to one of them. Among four diploid wild species in Arachis section, A. cardenasii and A. batizocai were rather closer than A. correntina and A. duranesis and both A. villosulicarpa in Extranervosae section and A. pusilla in Triseminalae section were all distant relatives.
