The plant hormone ethylene is a combatant for salinity in most plants. Ethylene is known for regulating plant growth and development and adapted to stress conditions through a complex signal transduction pathway. Central membrane proteins in plants, such as ETO2, ERS1 and EIN2, are used for ethylene signaling in many plant growth processes.
Ethylene chemical structure. Ethylene signaling pathway is a signal transduction in plant cells to regulate important growth and developmental processes. [1] [2] Acting as a plant hormone, the gas ethylene is responsible for promoting the germination of seeds, ripening of fruits, the opening of flowers, the abscission (or shedding) of leaves and stress responses.

Within the 20-year timespan, many scientists have actively contributed to examining and reevaluating Hager's acid-growth hypothesis. Despite the accumulation of observations that evidently identify the final target of the auxin-induced action to be H +-ATPase, which excretes H + protons to the apoplast and take in K + ions through its rectifying K + channel in the following years, the ...

Ethylene-responsive element binding protein (EREBP) is a homeobox gene from Arabidopsis thaliana and other plants which encodes a transcription factor. [2] EREBP is responsible in part for mediating the response in plants to the plant hormone ethylene .
[3] [4] It is synthesized by the enzyme ACC synthase (EC 4.4.1.14) from methionine and converted to ethylene by ACC oxidase (EC 1.14.17.4). [ 5 ] ACC also exhibits ethylene-independent signaling that plays a critical role in pollination and seed production by activating proteins similar to those involved in nervous system responses in humans ...
Auxin, a plant hormone that allows for cell elongation, is accumulated during the initial growing and developmental phases of the plants life cycle. During ethylene gene induction it was found that auxin related genes (aux/IAA and AUX1) represents the transcription factors that induce 1-MCP.
Programmed senescence seems to be heavily influenced by plant hormones.The hormones abscisic acid, ethylene, jasmonic acid and salicylic acid are accepted by most scientists as promoters of senescence, but at least one source lists gibberellins, brassinosteroids and strigolactone as also being involved.
