SQUAMOSA-Promoter Binding Protein Like 10/14 (OsSPL10/14) Regulate Salt Tolerance by Modulating Reactive Oxygen Species Homeostasis in Rice (Oryza Sativa L.).

ABSTRACT: Soil salinization seriously impacts the growth and development, yield, and grain quality of crops. Elucidating the molecular underlying of salt tolerance is crucial for advancing stress-resistant molecular breeding research in crops. Here, we identified a salt stress-responsive gene, SQUAMOSA-promoter binding protein like 10 (OsSPL10), and characterized its molecular function in conferring salt tolerance to rice. Firstly, we generated and characterized three distinct types of spl10 mutants using CRISPR/Cas9 mutagenesis. In spl10 mutant, the leaf withered rate was lower than that in wild type (WT), the plant height and fresh weight per plant of spl10 were higher than WT under salt stress, indicating that spl10 exhibits tolerance to salt stress. Based on biochemical and physiological assays,
