| 摘 要： | 重力反应是植物对环境的一种适应现象。生长素参与植物环境适应与发育调控的过程,重力反应过程的核心之一是在重力反应器官形成生长素的浓度梯度,诱导下游基因的差异表达。生长素的合成、代谢、极性运输及信号转导在此过程中发挥了关键作用。该文以拟南芥和水稻的研究为基础,综述了近几年对生长素调控植株重力反应的分子机理的研究进展,并对该领域未来的研究进行展望。

| Abstract: | Gravitropism of higher plants is one of the fundamental adoptive responses upon environmental stimuli. Auxin,the most important plant hormone that is involved in almost every process of plant growth and development,has been proven to be an indispensable factor that determines the process of gravitropism. Asymmetrical auxin distribution within plant organs might explain the mechanism of tropic growth,which in turn triggers the differential expression of downstream genes.The biosynthesis,catabolism,polar tran... |
