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. [3]
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.
The reaction catalyzed by 1-aminocyclopropane-1-carboxylic acid synthase (ACS) is the committed and rate-limiting step in the biosynthesis of ethylene [20], a gaseous plant hormone that is responsible for the initiation of fruit ripening, shoot and root growth and differentiation, leaf and fruit abscission, flower opening, and flower and leaf ...
Plant hormones (or phytohormones) are signal molecules, produced within plants, that occur in extremely low concentrations. Plant hormones control all aspects of plant growth and development, including embryogenesis, [1] the regulation of organ size, pathogen defense, [2] [3] stress tolerance [4] [5] and reproductive development. [6]
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 .
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 ...
ACC is the precursor 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).
