Abstract

Thioredoxins (TRXs) are small oxidoreductase proteins located in various subcellular compartments. Nucleoredoxin (NRX) is a nuclear-localized TRX and a key component for the integration of the antioxidant system with the immune response. Although NRX is well characterized in biotic stress responses, its functional role in abiotic stress responses is still elusive. To understand whether NRX contributes to heat stress response in tomato (Solanum lycopersicum), we generated CRISPR/Cas9-mediated mutations in SlNRX1 (slnrx1). Interestingly, the slnrx1 mutant was extremely sensitive to heat stress with higher electrolyte leakage, malondialdehyde contents, and H
