Arabidopsis Transcriptome or Gene expression
Salt stress is one of the abiotic stresses affecting crop growth and yield. The functional screening and mechanism investigation of the genes in response to salt stress are essential for the development of salt-tolerant corps. Here, we found that Arabidopsis OXIDATIVE STRESS 2 (OXS2) is a salinity-induced gene, and its loss-of-function mutant (oxs2-1) is hypersensitive to salt stress during seed germination and root elongation processes. To explore the molecular mechanism of OXS2 in salt tolarance, its subcellular localization was detected with or without salinity; and the alteration of gene expressions between the wild-type and oxs2-1 was measured. The results revealed that AtOXS2 was predominantly localized in the nuclear upon salt stress, whereas AtOXS2 was primarily expressed in the cytoplasm under the control condition. Transcriptomic analysis revealed that multiple genes and pathways were downregulated under salt stress in the oxs2-1 plants compared with those in the wild-type plants. In conclusion, our results indicated that OXS2 confers salt tolerance in Arabidopsis through multiple stress-dependent pathways
