What is ABA abscisic acid? The ABA is a type of acid known as abscises or abscisic acid, ABA perception and signaling pathways are involved in any abiotic process
what is Abscisic Acid
Abscisic acid (ABA) is the most important regulator of the dehydration response in plants,
the MAPK and ABA perception and signaling pathways are involved in any abiotic process that involves decrease of pressure and water loss

uses or importance of abscisic acids in plant
ABA was originally believed to be involved in abscission, which is how it received its name. This is now known to be the case only in a small number of plants. ABA-mediated signaling also plays an important part in plant responses to environmental stress and plant pathogens.The plant genes for ABA biosynthesis and sequence of the pathway have been elucidated. ABA is also produced by some plant pathogenic fungi via a biosynthetic route different from ABA biosynthesis in plants
The ABA-induced stomata closure reduces transpiration (evaporation of water out of the stomata), thus preventing further water loss from the leaves in times of low water availability. A close linear correlation was found between the ABA content of the leaves and their conductance stomata resistance on a leaf area basis
