赤霉素生物合成与信号传递对植物株高的调控

Regulation of plant height by gibberellins biosynthesis and signal transduction

摘要:

植物株高是影响作物产量和品质的重要农艺性状。赤霉素 (Gibberellins，GAs) 是调控植物株高的重要激素，GA相关株高基因的克隆与分子机制研究对于合理调控作物生长发育和农业生产具有极其重要的利用价值，在水稻、小麦等粮食作物育种中得到了广泛应用。为了促进GA在果树、花卉等园艺作物育种中的有效利用，文中在分子生物学水平上介绍GA生物合成和GA信号传递途径对植物株高的调控。

Abstract:

Plant height is one of the most important agronomic traits that could affect both crop yield and quality. Among all the hormones, gibberellins are crucial to regulate plant height. Cloning and molecular mechanism research of the plant height genes associated gibberellins have extremely important value for the regulation of crop growth and agricultural production, and have been widely used in rice, wheat and other grain crops breeding. In order to promote utilization of gibberellins in fruit trees, flowers and other horticultural crops breeding, we reviewed the regulation of plant height by gibberellins biosynthesis and signal transduction at the molecular level in this paper.
