摘要
Ethylene influences many plant growth and developmental processes. To achieve this diversity of function, the biosynthesis of this gaseous hormone is tightly regulated by a diverse array of factors, including developmental cues, wounding, biotic and abiotic stresses, and other phytohormones. Many studies have demonstrated that differential transcription of 1-aminocyclopropane-1-carboxylate synthase (ACS) gene family members is an important factor regulating ethylene production in response to different stimuli. Recently, several studies, focusing primarily on the Arabidopsis eto mutants, have indicated that the regulation of ACS protein stability also plays a significant role in the control of ethylene biosynthesis. Here, we review this post-transcriptional control of ethylene biosynthesis and discuss the mechanisms that underlie it.
