Growth and productivity are regulated by several important phytohormones in plants. Phytohormones are beneficial moieties resulting from different metabolic mechanisms and are significant regulators of various phases of plant growth and development. Among these phytohormones, ethylene is recognized as a multifaceted “aging” hormone because of its versatile role in modulating developmental functions such as fruit ripening, senescence, and abscission. It also controls several other aspects of plant growth and development during the entire lifespan of the plant. Ethylene is also known to either promote or inhibit growth and senescence processes that vary with the plant species, the amount of ethylene, the timing of supplementation, and environmental conditions. Development and senescence of various plant parts include numerous genetic mechanisms in which ethylene is a crucial player, in association with other plant hormones, combining signals and permitting the commencement of circumstances suitable for phase development, reproduction, and longer duration of plant organs. Alterations in ethylene concentration, its acuity, and its crosstalk with other hormones directly or indirectly modulate the plant lifecycle. Therefore, crosstalk among ethylene and other plant hormones to control growth and development could offer a beneficial way to deploy the amount of these phytohormones via molecular technologies and achieve definite plant responses. The detection of novel cooperative or antagonist associations between ethylene and other phytohormones has a significant capacity to modulate various progressions of plant development and improve plant productivity and quality.
