The recent discovery of genes involved in abscisic acid (ABA) biosynthesis and responses heralds a new era for seed physiology. Our understanding of the regulation of ABA biosynthesis is moving from a linear metabolic pathway to a spatial and temporal network that governs ABA action in seeds. Transcription factors involved in ABA signaling have been identified, together with their target sequences. This allows further analysis of the specificity of ABA signaling in a complex system of interacting factors.
最近对参与脱落酸(ABA)生物合成及响应的基因的发现,为种子生理学开创了一个新时代。我们对ABA生物合成调控的理解正从线性代谢途径转向一个在种子中控制ABA作用的时空网络。参与ABA信号传导的转录因子及其靶序列已被确定。这使得在一个由相互作用因子构成的复杂系统中,能够进一步分析ABA信号传导的特异性。
