BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Fruit growth depends on highly coordinated hormonal activities. The phytohormone gibberellin (GA ) promotes growth by triggering degradation of the growth-repressing DELLA proteins; however, the extent to which such proteins contribute to GA-mediated fruit development remains to be clarified.

Detailed explanation-2: -Gibberellins are plant hormones, and as such are responsible for a wide range of developmental processes throughout the life cycle of a plant. They stimulate growth in seeds, young leaves, and roots, are able to initiate seed germination, promote flowering, and increase fruit size.

Detailed explanation-3: -Fruit growth is mainly dependent on auxin and cytokinin It is now well established that seeds are rich source of hormones, particularly auxins, GA, and cytokinin, which are involved in stimulating growth of surrounding tissues and even determine the fruit size (Crane, 1964; Ozga et al., 2003).

Detailed explanation-4: -Gibberellin can delay the progress of some components of the ripening of fruit, preventing some of the changes triggered by ethylene.

Detailed explanation-5: -Gibberellins cause seed germination by breaking the seed’s dormancy and acting as a chemical messenger. Its hormone binds to a receptor, and calcium activates the protein calmodulin, and the complex binds to DNA, producing an enzyme to stimulate growth in the embryo.
