The regulation of ethylene biosynthesis: a complex multilevel …
2020年8月13日 · Introduction to the ethylene biosynthesis pathway. The volatile hormone ethylene is a major regulator of many developmental and physiological responses in plants (Abeles et al., 1992). As a gas, ethylene quickly diffuses from sites of production, where it can be perceived, but is not modified nor metabolised.
The Ethylene Pathway: A Paradigm for Plant Hormone Signaling …
In this review the ethylene biosynthesis and signaling pathway in the reference plant Arabidopsis thaliana are described. The questions of how the ethylene gas is produced and sensed by the receptor protein, and how the different pathway components function to transduce the signal to the nucleus, will be addressed.
The regulation of ethylene biosynthesis: a complex multilevel control ...
The gaseous plant hormone ethylene is produced by a fairly simple two-step biosynthesis route. Despite this pathway's simplicity, recent molecular and genetic studies have revealed that the regulation of ethylene biosynthesis is far more complex and occurs at different layers.
Ethylene Biosynthesis and Signaling: An Overview
2005年1月1日 · Genetic and biochemical studies have identified major factors that mediate ethylene biosynthesis and signal transduction. Substantial progress in the elucidation of the ethylene signal transduction pathway has been made, mainly by …
Ethylene Biosynthesis and Regulation in Plants | SpringerLink
2014年10月29日 · Ethylene is synthesized from S -adenosylmethionine (SAM) via 1-aminocyclopropane-1-carboxylic acid (ACC). In plants, ACC synthase (ACS) and ACC oxidase (ACO), two key enzymes in the ethylene biosynthetic pathway, are tightly regulated both transcriptionally and posttranscriptionally to modulate ethylene biosynthesis.

Genetic and biochemical studies have identified major factors that mediate ethylene biosynthesis and signal transduction. Substantial progress in the elucidation of the ethylene signal transduction pathway has been made, mainly by research on Arabidopsis thaliana.
Ethylene Biosynthesis - SpringerLink
Many microbes among bacteria and fungi produce ethylene from two possible pathways: (i) a methionine and 2-oxo-4-methylthiobutyric acid (KMBA 1) pathway in which ethylene is formed from KMBA by chemical reaction, and (ii) an α- ketoglutaric acid (KGA) pathway in which KGA is generated from glucose and many other substrates and an ethylene ...
dedicated to ethylene biosynthesis, much of the regulation of overall ethylene production occurs by manipulating transcription, translation and protein stability of these two enzymes. Addition-ally, metabolic regulation of ethylene production is achieved by ACC homeostasis, which encompasses ACC biosynthesis, trans-port and conjugation.
Insights into the genes involved in the ethylene biosynthesis pathway ...
2020年10月19日 · The natural diversity of ethylene production suggests that plants by fine-tuning biosynthetic of ethylene and signaling pathways can adapt to different environments. Observation of some stress-responsive genes revealed that this adaptation could be associated to modify the expression of ACS genes via epigenetic modifications [ 8 , 15 ].
