【摘要】 独脚金内酯(strigolactones, SLs)是一种新型的植物激素，参与调节植物分枝、生殖发育及叶片衰老等多种生物学过程。D53/SMXLs是独角金内酯信号转导通路中的抑制因子，在独脚金内酯信号转导中起重要作用。介绍了国内外最新关于独脚金内酯信号抑制因子D53/SMXLs的进展，综述了D53/SMXLs的发现、结构、信号转导机制、分子生物学功能及其他功能的研究成果。最后从三方面指出独脚金内酯信号途径有待完善与研究的内容。更多还原

【Abstract】 Strigolactones(SLs) is a new type of plant hormone, which is involved in regulating plant branching,reproductive development, leaf senescence and other biological processes. D53/SMXLs is an inhibitor of monolactone signal transduction pathway, and plays an important role in monolactone signal transduction. The previous studies about strigolactones inhibitory factor D53/SMXLs at home and abroad were reviewed. The discovery, structure, signal transduction mechanism, molecular biological functions and other functions of D53/SMXLs were summarized. At last, it was pointed out that the three aspects of strigolactones signal transduction pathway should be further improved and studied.更多还原
