Abstract:

Protein glycosylation modifications play a crucial role in regulating numerous biological processes, with significant advancements made, particularly in the areas of plant and animal development as well as responses to abiotic and biotic stressors. O-GlcNAcylation (O-GlcNAc) and O-Fucosylation (O-Fuc) are two important types of protein modifications. Among them, SECRET AGENT (SEC) and SPINDLY (SPY) are key homologous proteins of O-GlcNAc transferase (OGT), responsible for O-GlcNAc modification and O-Fuc modification, respectively. They play crucial roles in plant growth, development, and stress response processes. This review provides a comprehensive overview of the O-GlcNAc and O-Fuc modification processes of proteins and their associated enzymes. It analyses the evolutionary characteristics of SEC and SPY, highlights their regulatory mechanisms in plant development and stress responses, and discusses future research hotspots and challenges in plant protein glycosylation modifications.

Key words: O-GlcNAcylation, O-Fucosylation, plant development, response to adversity
