Abstract

Successful reproduction is essential for species survival and crop breeding.Fertility can be impacted at multiple levels, including gene expression, protein activity, and cellular processes, all of which are tightly regulated by post-translational modifications (PTMs) (Millar et al., 2019; Zhou et al., 2023).S-nitrosylation (also known as S-nitrosation) is a type of protein PTM in which a nitric oxide (NO) group is added to the sulfur atom of a cysteine residue.S-nitrosylation can alter protein function, stability, and protein interaction with other molecules.Nitrosoglutathione (GSNO) serves as a major buffer for NO, and it can be reduced by the S-nitrosoglutathione reductase (GSNOR).GSNOR therefore plays an
