Rice blast,caused by the fungus Magnaporthe oryzae,is a significant fungal disease to rice Oryza sativa production.Understanding the interaction mechanisms between rice and M.oryzae contrib-utes to the identification of excellent resistance genes,thus providing genetic resources for breeding rice varieties resistant to rice blast.Ubiquitination,a type of post-translational modification in eukaryotic cells,plays a crucial role in various processes such as plant growth,development and stress response.With the continuous advancement of biotechnology,research into the interactions between rice and M.oryzae has achieved tremendous progress.Recently,multiple rice ubiquitin modification-related pro-teins have been identified as key players in rice immunity using ubiquitylome analysis,ubiquitination interactome and protein function assays.This article provides an overview of the ubiquitination path-way and reviews the research progress on E2 ubiquitin-conjugating enzymes,E3 ubiquitin-ligases,and deubiquitinating enzymes,and their involvement in pathogen-associated molecular pattern-triggered im-munity(PTI)or effector-triggered immunity(ETI)in rice.Furthermore,this review also discusses scien-tific questions that urgently need to be addressed in this field and explores future directions,aiming to provide reference and guidance for further research into ubiquitination modification in plant immune processes.
