doi:10.16819/j.1001-7216.2026.250616

Abstract

Abstract:

E3 ubiquitin ligases determine substrate specificity and therefore play important roles in the ubiquitination process. Rice is one of the most important cereal crops, and recent studies have shown that E3 ubiquitin ligases are involved in regulating various biological processes in rice. This manuscript summarizes the reported E3 ubiquitin ligase genes in rice, elucidates the molecular mechanisms of E3 ubiquitin ligases in regulating rice growth, development, and stress response, and outlines further research prospects on E3 ubiquitin ligases, aiming to provide a theoretical basis and practical guidance for high-yield and stress-resistant breeding of rice.

Key words: rice, E3 ubiquitin ligase, growth and development, stress response
