Abscisic acid (ABA) is a plant hormone that is derived from carotenoids. ABA triggers a number of plant responses including seed dormancy, maturation, germination and adaptive responses to drought stresses. My research team performed molecular genetics and functional genomics research and revealed some novel mechanisms of ABA-mediated transcription in seeds and of dynamic regulations of ABA biosynthesis and catabolism. Our analysis indicates that vascular parenchyma cells play a central role in ABA biosynthesis, whereas ABA catabolism is activated locally in various cell types suggestive of a link to its signaling pathway.
