在“绿色革命”期间，小麦和水稻产量的显著提高是通过将矮化性状引入植物而实现的。现在，对导致这些性状的基因的鉴定表明，它们干扰赤霉素（GA）植物激素的作用或产生。我们知道小麦的Rht基因编码通常被赤霉素抑制的生长抑制因子，并且最近的研究表明水稻的sd1基因编码赤霉素生物合成途径中的一种有缺陷的酶。
The spectacular increases in wheat and rice yields during the 'Green Revolution', were enabled by the introduction of dwarfing traits into the plants. Now, identification of the genes responsible for these traits shows that they interfere with the action or production of the gibberellin (GA) plant hormones. We knew that the wheat Rht genes encode growth repressors that are normally suppressed by GA, and recent work shows that the rice sd1 gene encodes a defective enzyme in the GA-biosynthetic pathway.
