BIOMOLECULES AND ENZYMES

Detailed explanation-1: -The transition from dormancy to germination in seeds is a key physiological process during the lifecycle of plants. Abscisic acid (ABA) is the sole plant hormone known to maintain seed dormancy; it acts through a gene expression network involving the transcription factor ABSCISIC ACID INSENSITIVE 3 (ABI3).

Detailed explanation-2: -However, abscisic acid (ABA) is the only hormone known to induce and maintain seed dormancy.

Detailed explanation-3: -Abscisic acid is one of the major plant hormones involved in many aspects of plant growth and developmental processes including seed dormancy and germination.

Detailed explanation-4: -Auxin is one of the classic phytohormones effective during tropism growth and tissue differentiation. Recent studies, however, show that auxin possesses positive effects on seed dormancy, which suggests that auxin is the second phytohormone that induces seed dormancy, besides ABA.

Detailed explanation-5: -It has an essential role in multiple physiological processes of plants, such as stomatal closure, cuticular wax accumulation, leaf senescence, bud dormancy, seed germination, osmotic regulation, and growth inhibition among many others.
