摘 要: 玉米胚乳的重量占玉米籽重的80%~85%,胚乳细胞的分裂和发育状况决定着籽粒的重量和品质。而植物的胚乳发育是一个高度程序化的过程,在多个层面上受到精确调控,其发育及调控机制是生殖与发育生物学领域中的前沿科学问题。挖掘调控玉米胚乳发育的重要功能基因,阐明胚乳发育的分子调控机理,不但具有重要的理论意义,而且具有广泛的应用价值。而细胞周期蛋白依赖激酶抑制因子KRPs主要通过结合并抑制细胞周期蛋白依赖激酶(cyclin dependent kinases,CDKs)和细胞周期蛋白(cell cycle proteins,CYCs)的活性来调控细胞周期进程,在阻止细胞分裂、响应环境信号等方面起着非常重要的作用。鉴于KRPs的重要生物学功能,研究将就KRPs调控玉米胚乳发育的分子机制进行综述。

Abstract: For that the maize endosperm weight is about 80%-85% of corn grain, endosperm cell division and growth condition determines seed weight and quality. While the plant endosperm is a highly programmed process, and is precisely controlled in many aspects, its development and regulation mechanism is the frontier scientific issue in the field of reproductive and developmental biology. To elucidate the molecular regulation mechanism of endosperm development, not only has important theoretical significance, but also has wide application value. The cyclin dependent kinase inhibitor KRPs mainly by binding and inhibiting cyclin dependent kinases (CDKs) and cell cycle proteins (CYCs) activity to regulate cell cycle progression, plays a very important role in preventing cell division in response to environmental signals. In view of the important biological function of KRPs, the molecular mechanism of KRPs in regulation of maize endosperm development was discussed.
