|a Trehalose may improve plant stress tolerance by regulating gene expression under different abiotic stresses. DNA methylation is involved in plant growth and development, but also in response to abiotic stresses. 5-azacytidine is a widely used inhibitor of DNA methylation. In this study, tomato (Solanum lycopersicum L. 'Ailsa Craig') was used as experimental material to explore the effects of trehalose and DNA methylation on the growth and development in tomato seedlings under salt stress. 10 mM trehalose, 50 μM 5-azacytidine, and their combined treatments could significantly increase growth parameters in tomato under salt stress, indicating trehalose and 5-azacytidine might play crucial roles in alleviating salt stress both synergistically and independently. Additionally, trehalose significantly down-regulated the expression of DNA methylase genes (SlDRM5, SlDRM1L1, SlCMT3 and SlCMT2) and up-regulated the expression of DNA demethylases genes under salt stress, suggesting that trehalose might regulate DNA methylation under salt stress condition. Under salt stress, trehalose and 5-azacytidine treatments enhanced antioxidant enzyme activity and induced antioxidant enzyme gene expression in tomato seedlings. Meanwhile, trehalose and 5-azacytidine increased ABA content by regulating the expression of ABA metabolism-related genes, thereby enhancing salt tolerance in tomato. Altogether, these results suggest that trehalose conferred salt tolerance in tomato seedlings probably by DNA demethylation and enhancing antioxidant capability and ABA accumulation
