摘要: 植物在水分胁迫条件下以依赖ABA和不依赖ABA的基因表达途径来调节对逆境的适应。植物通过渗透感受器感知胁迫信号,以MAPK和CDPK等途径传递信号,最终引起基因表达。

关键词: 水分胁迫, 基因表达, 信号转导, 渗透感受器, MAPK途径, CDPK途径

Abstract: The adaptation of plants to water stress is regulated by the ABA-dependent gene expression pathway and the ABA-independent gene expression pathway. The stress signals are sensed by the osmosensors at the cydtomembrane and transducted to the nucleus to cause the gene expressions by the MAPK signal-transduction pathway and the CDPK signal-transduction pathway.

Key words: water stress, gene expression, signal transduction, osmosensors, MAPK signal-transduction pathway, CDPK signal-transduction pathway
