太谷核不育小麦系由显性雄性不育单基因(简称Tal)控制的杂合体,它的异交后代总是分离出不育株和可育株两种等比(1:1)的类型。为了探索显性雄性核不育的分子遗传机理,许多学者已对它进行了细胞学及生理、生化方面的研究:如小孢子不同发育时期的显微观察;不育株和可育株花药内游离氨基酸成份的比较分析及脯氨酸代谢上的变化;同工酶
The Taigu nuclear sterile wheat is a hybrid controlled by a dominant male sterility single gene (Tal), and its outcrossing progeny always separate two kinds of equal ratio (1: 1) of sterile and fertile plants Types of. In order to explore the molecular genetic mechanism of dominant male sterility, many scholars have carried out cytological and physiological and biochemical aspects of the study: Microscopic observation of microspore at different developmental stages; Sterile and fertile anthers Comparative Analysis of Free Amino Acids and Changes in Proline Metabolism; Isoenzymes
