WebMay 10, 2011 · Main Text Introduction. Abscisic acid (ABA) is a stress-related signaling molecule reported in all kingdoms of life except in Archaea. Although well known and best studied in higher plants, in particular in Arabidopsis thaliana, there is evidence that the hormone is synthesized in plant-associated bacteria, plant pathogenic fungi, certain …
WebDec 9, 2024 · During evolution, ZcPYL8 has gained ABA interactivity and so has been able to be finely and dynamically tuned by a small endogenous mobile molecule instead of simply by its own abundance. WebHere, we discuss the evolution of three major signalling pathways that are known to control stomatal movements in angiosperms in response to light, CO 2, and abscisic acid (ABA). We examine the evolutionary origins of key signalling genes involved in these pathways, and compare their expression patterns between an angiosperm and moss.
WebThe emerging picture is that the ancestor of land plants and its predecessors synthesized ABA, as its biosynthetic pathway is conserved between ancestral and current day … WebIn two species (A. thaliana and O. sativa), duplicate genes related to ABA signaling pathways contribute to the expression variation in different organs or stress …
WebAug 27, 2024 · Moreover, ABA-inductions of Thau1/2/3/4 were largely dependent on the intact ABA signaling pathway mediated by PYR/PYL receptors. Among the many ABA-responsive genes affected by the defects of Thau1/2/3/4 , reduced expression of P5CS1 with decreased accumulation phenotype of prolines indicates that compromised proline …
