| 摘 要： | 以水稻品种‘南粳44＇为材料,研究了植物激素对水稻分蘖芽生长及OsTB1、OsD3、OsD10和OsD27等基因表达的调控。结果表明,水稻分蘖芽生长的调控至少存在两条途径,一条通过调控分蘖芽中CTK含量进而调控OsTB1等基因表达来实现,另一条通过调控OsD3、OsD10和OsD27等系列基因表达来实现。外源IAA和GA_3对水稻分蘖芽生长的调控是通过这两条途径共同实现的。

| Abstract: | In the present study,'Nanjing 44' was used to investigate the effects of hormones on rice(Oryza sativa) tiller bud growth and the expression of OsTB1,OsD3,OsD10 and OsD27.The results show that external IAA and GA_3 might have regulated tiller bud growth by at least two means:one is regulating the CTK content and the expression level of OsTB1 in tiller buds,and another is regulating the expression levels of OsD3, OsD10 and OsD27 in tiller buds. |
