| Abstract: | In this study,different Miscanthus lutarioriparius genotypes and Miscanthus×giganteus were used as test materials to explore the correlation between physiological responses and gene expression under salt stress. Those materials were treated with 0%,0.2%,0.5%,0.8% NaCl solutions individually. The expression of MlNAC2 gene and 6 physiological indexes were detected,and the correlation was analyzed. The results showed that the changes of MlNAC2 gene varied greatly among different materials,L2,L6,L9,and P1 increased more than 10 times while L1,L5,L8,and L10 changed less than 3 times. All materials were significantly different from the control in chlorophyll content,net photosynthetic rate,stomatal conductance,and proline,while some materials were not significantly different from the control in malondialdehyde content and superoxide dismutase activity. Correlation analysis showed that a series of photosynthetic factors referring to chlorophyll content,net photosynthetic rate,and stomatal conductance were related to MlNAC2 gene mostly. The results of this study can provide a reference for exploring the relationship between physiological response and molecular mechanism. |
