Abscisic acid (ABA) is one of the most important hormonal mediators of abiotic and biotic signals, and as such, ... For example, the AtRAC7/ROP9 protein is a modulator of both auxin and ABA signaling, but depending on growth and assay conditions, or perhaps level of expression, different studies have found that it can either stimulate or repress ABA and auxin responses [109,110]. Processes that convert C40 to xanthoxin (C15) all take place in plastids, and in the cytoplasm, ABA2 and AAO3 convert xanthoxin into ABA. Abscisic acid is synthesized in mature leaves and transported both to the root and throughout the shoot system, primarily via the phloem. aka “ABA” It is produced in the roots of plants, and also in the terminal buds, and get transported up into the leafs to, as a plant hormone, regulate transpiration when the environment gets dryer. Plants synthesize ABA using the carotenoid pathway initiated from β‐carotene (C40). Wei Lei et al . Abscisic acid: is a growth inhibitor. Roots also can synthesize abscisic acid and transport the hormone into the shoot in response to water stress.

Abscisic acid (ABA) has a crucial function in stress physiology, but little information is available for methods describing ABA determination in cowpea and its relationship to drought stress based on cowpea varieties with different capability of drought resistance.

Abscisic acid (ABA) is one of the "classical" plant hormones, i.e. Water stress results in a large increase in abscisic acid synthesis, as do short days in some photoperiodically sensitive plants.
