摘要
Abstract
Chemical control of the ineffective tillering in high-yield rice cultivation has been the hotspot and the future research direction. However, the appropriate chemical regulator has not been found yet. Strigolactones are newly discovered hormone precursors and have been shown in the regulation of rice tillering, while the regulation mechanism and signal transduction pathways of strigolactones are still unclear. In this study, the author summarized the regulation of strigolactones on rice tillering, the synthesis and signal transduction pathway of strigolactones, and the mechanism of strigolactones in controlling rice tillering. It is considered that strigolactones are able to inhibit the tillering of rice, and it might play a role in two pathways, by preventing auxin export in tiller buds or inhibiting buds outgrowth through directly entering tiller buds. The author also discussed current problems in the research, and proposed the application prospect of strigolactones regulating the tillering in field production of rice.关键词
