BIOMOLECULES AND ENZYMES

Detailed explanation-1: -This increase in ethylene concentration triggers an increase in the fruit’s metabolism and causes the changes to the fruit that occur during ripening. Ripening of climacteric fruits can, therefore, be slowed down by reducing the amount of ethylene the fruits make or by blocking ethylene’s actions [5].

Detailed explanation-2: -Ethylene. The hormone ethylene has two functions. It (1) helps ripen fruit and (2) is involved in the process of abscission, the dropping of leaves, fruits, and flowers.

Detailed explanation-3: -In climacteric fruit, the plant hormone ethylene is the major cue that controls most aspects of ripening. By contrast, the ripening of nonclimacteric fruit does not strictly depend on ethylene, and the nature of the triggers of ripening in this type of fruit remains yet to be elucidated.

Detailed explanation-4: -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.
