ETHYLENE PATHWAY Meaning and
Definition
-
The ethylene pathway can be defined as a series of biochemical reactions and signaling mechanisms that are involved in the synthesis and perception of the plant hormone ethylene. Ethylene is a gaseous plant hormone that plays a crucial role in regulating various aspects of plant growth, development, and responses to environmental stresses.
In the ethylene pathway, the synthesis of ethylene is primarily catalyzed by the enzyme ACC synthase, which converts S-adenosylmethionine (SAM) into 1-aminocyclopropane-1-carboxylic acid (ACC). ACC is then converted to ethylene by the enzyme ACC oxidase. Once synthesized, ethylene is released into the surrounding environment.
The perception of ethylene occurs through a family of receptors known as ethylene receptors, which are present in the cell membranes. These receptors bind to ethylene and initiate a signaling cascade that leads to various cellular responses. The binding of ethylene to the receptor results in the inactivation of the repressor protein, allowing the activation of downstream transcription factors.
The transcription factors activated by the ethylene signaling pathway regulate the expression of numerous ethylene-responsive genes, which ultimately mediate the diverse effects of ethylene on plant growth and development. These effects include fruit ripening, leaf senescence, and responses to biotic and abiotic stresses.
In summary, the ethylene pathway is a complex network of biochemical reactions and signaling mechanisms that enable plants to synthesize and perceive ethylene, thereby regulating various physiological processes for adaptive growth and responses to environmental cues.

Etymology of ETHYLENE PATHWAY
The etymology of the word "ethylene pathway" can be broken down as follows:
1. Ethylene: The word "ethylene" comes from the combining form "ethylen-" derived from the chemical compound ethene. It was coined in the mid-19th century, derived from the Latin word "aethēr" meaning "ether" and the Greek word "hūlē" meaning "wood". Ethylene is a gaseous hydrocarbon used in various industries, including the production of plastics and as a plant hormone.
2. Pathway: The word "pathway" is composed of two parts, "path" and "way". "Path" comes from the Old English word "paþ" or "piþ" meaning "a beaten track or way", which originated from the Proto-Germanic word "paþaz".
