The invention discloses application of a TaNAC019B gene to improvement of salt stress damage resistance of plants, and belongs to the technical field of molecular biology. The amino acid sequence coded by the TaNAC019B gene disclosed by the invention is as shown in SEQ ID NO: 2. Compared with a receptor variety Fielder and TaNAC019Crispr wheat strain, the wheat strain overexpressed by the TaNAC019B has the advantages that the wilting degree is relatively poor after salt stress treatment, the seed grain length is relatively long, the grain width is relatively wide, the plant height is relatively high, and the thousand grain weight is relatively heavy; the SOD and POD activities of the leaves are relatively high, the MDA content is relatively low, the relative conductivity is reduced, the net photosynthetic rate, the stomatal conductance and the transpiration rate are increased, and the intercellular CO2 concentration is reduced; therefore, the TaNAC019B gene can improve the ability of wheat to resist salt stress harm, and has important application value in salt-tolerant wheat screening and salt-tolerant wheat variety breeding.

The application discloses genes LpCbDR3 In the application of improving the salt tolerance and forage quality of rye grass, transgenic RNAi- LpCbDR3 The crude protein content and fat of the rye grass are significantly improved, and the ADF, NDF and Ash contents are significantly reduced. LpCbDR3 The transgenic rye grass has a significantly improved chlorophyll content compared with the control group, which indicates that chlorophyll is degraded under the salt stress condition, and the transgenic plant can reduce the chlorophyll decomposition rate. LpCbDR3 The relative conductivity (EL) is significantly reduced, which indicates that the transgenic plant has a low ion permeability of leaf cell membrane and a low damage degree of cell membrane compared with the control group, and the harm of salt stress to the plant is alleviated. LpCbDR3 The forage quality and salt tolerance of perennial rye grass can be improved.
