BIOMOLECULES AND ENZYMES

Detailed explanation-1: -It is a growth-inhibiting hormone. ABAs act as an antagonist to GAs. It inhibits plant metabolism and regulates abscission and dormancy. It is also called “stress hormone” as it increases the tolerance of plants.

Detailed explanation-2: -Abscisic acid (ABA) is an important phytohormone regulating plant growth, development, and stress responses.

Detailed explanation-3: -Abscisic acid (ABA) is a key hormone involved in tuning responses to several abiotic stresses and also has remarkable impacts on plant defense against various pathogens. The roles of ABA in plant defense against bacteria and fungi are multifaceted, inducing or reducing defense responses depending on its time of action.

Detailed explanation-4: -ABA(Abscisic acid) is called a stress hormone.

Detailed explanation-5: -Abscisic acid is a growth inhibitor hormone in plants. It acts as an antagonist to gibberellic acid. It is also referred to as a stress hormone, as it increases tolerance during stress conditions.
