Popis: The most hazardous abiotic stress, salinity, restricted the world crop production, and grain chalkiness affected the grain quality to limit consumers' acceptance. The basic helix-loop-helix (bHLH) proteins modulate massive biological processes in plants. Here the CRISPR/Cas9 gene editing mutants were obtained to detect the function of OsbHLH044. The loss-of-function of OsbHLH044 mutants showed numerous altered plant phenotypes. Notably, the osbhlh044 mutants resulted in prominently reduced morphological and physiological parameters under salt stress. Lower antioxidant activities and higher lipid peroxidation and hydrogen peroxide (H
