We adapted a previously reported protocol for detecting protein SNOs in animal systems (King et al., 2005) for plant samples. Briefly, proteins from plant samples are separated via non-reducing SDS-PAGE, then the NO bound by S-nitrosylated proteins is released using UV light and, finally, the NO is detected using the fluorescent probe DAF-FM (Rodriguez-Ruiz et al., 2017). Thus, the approach presented here provides a relatively quick and economical procedure that can be used to compare protein SNOs content in plant samples and provide insight in NO-based signaling in plants.
