Effect of Hormones on the Growth of Rice Tiller Bud and the Expression of the Genes Related to Tiller Growth

Ding Yan, Wang Shao

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.
