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: -Abscisic acid (ABA) and ethylene are the major regulators of ripening and senescence in both dry and fleshy fruits, as demonstrated by numerous ripening-defective mutants, effects of exogenous hormone application, and transcriptome analyses.

Detailed explanation-3: -Gibberellin can delay the progress of some components of the ripening of fruit, preventing some of the changes triggered by ethylene.

Detailed explanation-4: -Fruit development can generally be divided into three major stages: growth, maturation, and senescence.

Detailed explanation-5: -Gibberellins can be used to: end seed dormancy. promote flowering. increase fruit size.
