The MsNAC73-MsMPK3 Complex Modulates Salt Tolerance and Shoot Branching of Alfalfa via Activating MsPG2 and MsPAE12 Expressions.

ABSTRACT: Balancing plant growth and survival is an important strategy for plants to adapt to different environments. However, the molecular mechanisms of the balance strategy are poorly understood. Our previous study demonstrated that MsNAC73 interacts with the promoter of MsPAE12, which positively regulates alfalfa shoot branching. In the present study, MsNAC73 was further found to interact with the promoter of MsPG2 and negatively regulate MsPG2 expression through MODMS database analysis and experimental verification (Y1H, EMSA and Dual-LUC assays). The transgenic alfalfa plants with overexpression or knockdown of MsNAC73 and MsPG2 were obtained, and their responses to abiotic stress were analysed. Overexpressing MsNAC73 negatively and overexpressing MsPG2 positively affected the salt tolerance o
