水稻中乙烯生物合成关键酶OsACS和OsACO调控机制研究进展OA北大核心CSTPCD

Ethylene plays a pivotal role in regulating the growth,development and stress responses of rice(Oryza sa-tiva).The first step of ethylene biosynthesis is the conversion of methionine to SAM,followed by the synthesis of the ethy-lene precursor ACC under the catalysis of ACC synthase,which is ultimately converted to ethylene by ACC oxidase.In this review,we provide an overview of the latest research progress,especially focusing on the transcriptional and post-translational regulatory mechanisms of two key enzymes involved in the rice ethylene biosynthesis pathway,OsACS and OsACO.Finally,we present several unsolved questions and insights into future research directions to enhance our un-derstanding of the complex mechanism of ethylene biosynthesis.
