摘要
Opaque 2蛋白是玉米中重要的转录激活因子,该基因的自然突变体o2会使玉米籽粒中赖氨酸含量大幅增加,文中综述了Opaque2基因的结构和该蛋白对玉米中醇溶蛋白基因、胞质丙酮酸磷酸双激酶(CyPPDK 1)基因、赖氨酸-酮戊二酸还原酶/酵母氨酸脱氢酶(LKR/SDH)基因、b32基因等的调控作用,以及o2突变体在玉米育种研究中的应用。
Opaque 2 is an important transcription activator,and its natural mutant of o2 will greatly increase the lysine content in maize grains. The paper reviewed the structure of Opaque 2 gene, and its regulation of zein gene, CyPPDK 1 gene, LKR/SDH gene and b32 gene, as well as the application of o2 mutant in maize breeding research.
