Ethylene

Detailed explanation-1: -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-2: -Ethylene is a gas and is known as the “fruit-ripening hormone.” Every fruit has a certain level of ethylene production throughout its lifecycle. However, in some fruits, ethylene levels shoot up when the fruit starts ripening.
Detailed explanation-3: -Ethylene plays a vital role in the natural ripening of fruits. It is a hormone produced naturally within the fruits to stimulate ripening process.
Detailed explanation-4: -Ethylene is responsible for the changes in texture, softening, color, and other processes involved in ripening. Ethylene level in under-ripe fruit is very low, but as fruit develop, the fruit produce larger amounts which speed up the ripening process or the stage of ripening.
