Definition of abscisic acid in English: abscisic acidnounabˈsɪsɪkabˌsisik ˈasid mass nounBiochemistry A plant hormone which promotes leaf detachment, induces seed and bud dormancy, and inhibits germination. 〔生化〕脱落酸 Example sentencesExamples - Analysis of mutant plants suggests that the plant hormones abscisic acid, ethylene and jasmonates are implicated in the long-distance signalling pathway and that the action may be mediated by reactive oxygen species.
- Subsequently, a signal transduction cascade involving at least four plant hormones, ethylene, auxin, abscisic acid, and gibberellic acid, is activated.
- The hormone abscisic acid induces a myriad of cellular responses in plants via complex signal transduction cascades, leading to tolerance towards various stresses, including cold, drought and salinity.
- When conditions are otherwise in favour of producing the submerged type morphology, an exogenous supply of the plant hormone abscisic acid at an optimal concentration induces aerial type characteristics.
- Of particular interest here is the amphipathic plant hormone abscisic acid.
Origin1960s: abscisic from abscisin (the earlier name for the hormone), from abscission.
