【摘要】 G蛋白(guanine nucleotide-binding protein,G-protein)包括Gα、Gβ、Gγ亚基,Gγ亚基又可以进一步分为Type A、Type B、Type C 3种类型。植物G蛋白影响株型建成、生物逆境与非生物逆境应答、养分利用效率和产量表现等。玉米G蛋白的相关研究主要集中于典型Gα和Type C Gγ亚基。综述了玉米G蛋白的研究现状,重点介绍了G蛋白的分子功能、G蛋白与玉米农艺性状的关联,并对今后玉米G蛋白研究工作进行了展望,以期为玉米G蛋白的相关研究提供参考。更多还原

【Abstract】 G-proteins comprise Gα,Gβ and Gγ subunits. Gγ subunits could be further classified into three types: Type A,Type B and Type C. Plant G-proteins are involved in various biological processes,including plant architecture determinant,biotic and abiotic stress response,nutrient-use efficiency,and yield performance. Currently,G-protein research in maize is limited in canonical Gα and Type C Gγ subunits. Here,we summarized recent advances of G-protein research in maize with focused on the introduction of agronomic relevance for G-proteins. We also proposed future research in maize G-protein field,which was expected to provide reference for G-protein research in maize.更多还原
