2020年8月6日 Plant and Cell Physiology 在线发表了高少培博士题为“Gibberellin metabolism and signalling: Targets for improving agronomic performance of crops”的特邀综述。

    赤霉素(GAs)是重要的一类植物激素，调节包括种子萌发、茎伸长、叶片大小、花粉成熟和花、果实和种子的发育等植物生长发育的各个方面。导致“绿色革命”的半矮秆作物正是GA合成或信号相关的基因的突变所导致，证实了对GA在提高作物产量方面的价值。在生产上也常常通过遗传或外源施用GA或GA生物合成抑制剂来调控GA状态来改良植物的生长和产量。在这篇综述中，我们总结了GA在作物生长和发育等各方面的作用，并提出了调控GA代谢和信号途径在作物改良中的一些极具潜力的靶点。
