Abstract:

The ubiquitin-proteasome system(UPS)is an important regulatory system for proteostasis in organisms. By means of degrading different target proteins,UPS participates in diverse cellular processes. SINA E3 ubiquitin ligase is a key type of E3 ubiquitin ligases of UPS,playing extensive and important biological functions. This research elaborated the functional research status of SINA E3 ubiquitin ligase since the first one was discovered in plant. Four main aspects of its functions,including in plant growth and development,plant responses under adverse environment,interactions between plant and other organisms and plant autophagy were expounded. Generally,all the reported functions of SINA E3 ubiquitin ligase in plant were summarized. Meanwhile,the existing issues and research prospects for functional study of SINA E3 in plant are proposed. Therefore,all the above would provide valuable reference for the further functional research of SINA E3 in the future.

Key words: SINA E3 ubiquitin ligase, growth and development, abiotic stress, interactions between organisms, autophagy
