Abstract:

SOS2 (Salt Overly Sensitive 2) is a kind of important salt tolerance genes, which is involved in mediating the intracellular ion balance and plays an important role in the response of plants to salt damage and adaptation. In this study, a 1462 bp full-length cDNA, including a 1341 bp open reading frame, was isolated and harvested by RACE method. As the gene showed more than 70% homologous to members of SOS2 subfamily in other plants by bioinformatics analysis, it is then named as AhSOS2 (GenBank accession numberHG797656). Its coding protein AhSOS2 has 446 amino acids, and is a member of serine/threonine protein kinases. Quantitative real-time PCR (qRT-PCR) analysis showed that AhSOS2 was expressed constitutively in peanut tissues, and could be induced to express higher under salt and drought treatments. When treated with 250 mmol L-1 NaCl, the gene expression level increased dramatically to about 30 times higher than that of control in the stems of peanut seedlings, while the expression level of AhSOS2 increased markedly in the leaves of peanut seedlings when treated by drought stress that imitated by 30% PEG-6000.AhSOS2 is supposed to participate in stress resistance and tolerance in peanut. The expression binary vector of pCAMBIA1301P-AhSOS2 was constructed and the transgenic rice plants were obtained. The primary functional verification showed that the ability of salt tolerance and adaptation was enhanced in AhSOS2 overexpression rice. The above research is expected to uncover the adversity defense mechanisms of peanut grown under stress conditions, and further guide the resistance breeding and quality improvement of peanut.
