Abstract: S-nitrosylation, a newly identified cGMP-independent nitric oxide (NO) signaling pathway, is a post- translational modification in which NO moiety is covalently attached to the cysteine thiol group of a target protein, thereby leading to functional changes of modified proteins. Here, we review the recent progress in understanding the roles of S-nitrosylation in plant cell death and disease resistance, two closely interconnected biological processes. We summarize how NO promotes or inhibits cell death and disease resistance though S-nitrosylation of key proteins that participate in certain biological processes. We also give our comments on the inconsistent results regarding the role of S-nitrosylation in cell death and disease resistance from different groups. From the most recent progress made in animal systems, we provide perspectives for plant biologists in this field.

Key words: cell death, disease resistance, nitric oxide, S-nitrosogluta thionereductase (GSNOR1), S-nitrosylation
