Abstract：High-quality seed is a key indicator of advanced agricultural practices.With the national focus on the development of the seed industry，research on seed vigor has become an increasingly prominent and prioritized topic in recent years.Understanding the mechanisms that regulate seed vigor are crucial for future advancements in germplasm innovation， breeding of improved varieties，germplasm resource conservation，seed pro cessing，storage，and quality control. As an ireplaceable redox buffer in plants，glutathione（GSH） and its associated metabolism and regulatory factors have been increasingly recognized for their critical role in seed vigor.This review systematically examined the dynamic metabolic regulation of GSH throughout seed development，aging，and germination processes.We highlighted the multifaceted roles of GSH in maintaining seed vigor through its involvement in reactive oxygen species homeostasis，protein redox modifications，mitochondrial structure and function preservation，detoxification of reactive carbonyl compounds，and interactions with diverse signaling molecules.By synthesizing current evidence on exogenous GSH applications and their impacts on seed performance，we proposed an integrated model depicting GSH-mediated pathways in seed vigor regulation.The review concluded by identifying critical research gaps and suggesting promising avenues for future investigations to advance our understanding of GSH functions in seed biology and its potential applications in seed quality improvement.
