Biological Function Insights into the Ubiquitin/26S Proteasome Pathway in Rice
摘要
Abstract
There are two different protein degradation patterns in vivo,one pattern is energy-dependent and another is energy-independent.Ubiquitin/26S proteasome pathway (UPP) is an exceedingly high-efficient,specific and ATPdependent route for protein removal.In eukaryote,ubiquitin/26S proteasome pathway is involved in 80％～ 85％ protein degradation.In plant species,the ubiquitin/26S proteasome pathway regulates fundamental processes of growth and development,and it is one of the most important and fine regulation mechanisms for protein efficient and specific degradation in plants.This paper summarized the ubiquitin/26S proteasome pathway,and emphasized on the protein structure of E2 and E3 and their biological function and mechanism in rice growth and development,hormone signaling,biotic and abiotic stress response.The paper also prospected the further study,which would be helpful for revealing the fine control process of ubiquitin/26S proteasome pathway during rice growth and development,thus to provide guidance and reference for rice stress resistance breeding.关键词
