Research Progress in the Effects of Ubiquitin-proteasome System on Plant Agronomic Traits

doi:10.13560/j.cnki.biotech.bull.1985.2022-0160

Abstract

Abstract:

At present, problems such as population explosion, environmental pollution and ecological destruction emerge one after another. Improving agronomic traits, such as increasing yield and enhancing stress tolerance, is the most important goal of crop genetic improvement and the basis of promoting high-quality agricultural development. The ubiquitin-proteasome system（UPS）is a rapid and selective system for the hydrolysis of redundant and damaged proteins produced by plant. Now, studies have found that the ubiquitin-proteasome system affects plant development, reproduction, and important agronomic traits, such as pathogen responses, induction of flowering, seed size, and so on. This review focuses on recent studies illustrating the important functions of the UPS components and subunits of the proteasome and describes how the UPS affect plant agronomic traits. Finally, the review discusses the future research hotspots and the potential for crop improvement with UPS.

Key words: UPS, subunits, plant, agronomic traits
