摘　　要：赤霉素作为重要的植物激素,参与了植物诸多发育过程的调控。一些涉及赤霉素生物合成和信号传导途径的重要调控基因对作物的株型、产量和品质能够产生积极的影响,已在农业生产中得到广泛应用。其中,Rht-1和sd-1等位基因由于分别赋予了小麦和水稻半矮化的特性,从而促成了20世纪后半叶的"绿色革命"。本文回顾了与"绿色革命"相关的赤霉素代谢调控在影响作物株高、产量、养分利用等方面的研究成果,并对未来如何合理开发和利用赤霉素调控基因,培育出更多的"绿色革命"作物品种进行了展望。Gibberellins(GAs)are very important plant hormones that control diverse aspects of plant growth and development.Some important regulatory genes involved in gibberellin biosynthesis and signaling transduction pathway positively impact plant architecture,yield and quality of cereal crops,which has been applied in agricultural production.The alleles of Rht-1 and sd-1,that confer a semi-dwarf feature to wheat and rice,respectively,underpin the‘Green Revolution’in the latter half of the twentieth century.This paper reviewed the research achievements on the GA metabolism regulation in impacting the height,yield,nutrition usage of‘Geen Revolution’varieties,and prospected how to develop and utilize GA regulation genes for breeding more‘Green Revolution’varieties in the future.
