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.

Early in the study of plant hormones, "phytohormone" was the commonly used term, but its use is less widely applied now. Plant hormones are not nutrients, but chemicals that in small amounts promote and influence the growth, [13] development, and differentiation of cells and tissues. The biosynthesis of plant hormones within plant tissues is ...
Ethylene is a hormone that affects the ripening and flowering of many plants. It is widely used to control freshness in horticulture and fruits. [20] The scrubbing of naturally occurring ethylene delays ripening. [21] Adsorption of ethylene by nets coated in titanium dioxide gel has also been shown to be effective. [22]
In plant biology, the hyponastic response is a nastic movement characterized by an upward bending of leaves or other plant parts, resulting from accelerated growth of the lower side of the petiole in comparison to its upper part. This can be observed in many terrestrial plants and is linked to the plant hormone ethylene.

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. [10]
Her research focused on plant hormones, seed biology and plant DNA repair. She is best known for her work on the gas ethylene, in particular for demonstrating that ethylene is a natural plant hormone, and that it is the major regulator of ageing and the shedding of leaves and fruits. She also originated the concept of the target cell as a model ...
