Overexpression of ZmDUF1644 from Zoysia matrella enhances salt tolerance in Arabidopsis thaliana

The DUF1644 family is a highly conserved and functionally unknown protein it has been demonstrated that significantly improved the salt tolerance of rice (non-halophytes). However, little understood about function gene in halophytes. This study aimed to investigate whether similar non-halophytes as halophytic species. functions ZmDUF1644 transferred from Zoysia matrella into non-halophytic Arabidopsis thaliana were investigated under stress (150 mM NaCl). Phylogenetic analysis clustered OsSDIP361 same group, which salt-tolerant genes rice. obtained results exhibited alleviated adverse effects on transgenic seedlings. maximum root length, fresh weight, photosynthetic pigment content seedlings obviously better than wild type. relative electrolyte leakage rate, Na+ content, Na+/K+ ratios relatively lower line type stress. Moreover, expression AtSOS2 was also higher wild-type concluded overexpressed salt-stressed thaliana, enhancing its tolerance. It first report glycophytic species or
