Abstract:

Ubiquitin-mediated proteolysis is an integral part of diverse cellular functions. As a component of the ubiquitin conjugation system, E3 ubiquitin ligase is the key element determining the substrate specificity of ubiquitination. E3 ligase plays an important role against various environmental stresses such as drought, salinity, chilling, and pathogen attack and has a function in plant growth and development. There are 4 different types of E3 ubiquitin ligases: RING, U-box, HECT, and F-box. We summarize the recent progress in the function of U-box E3 ubiquitin ligases in plant biotic/abiotic stress resistance and development. We also discuss possible directions that might provide valuable information for further research of the regulation of ubiquitin-mediated plant proteolysis.
