Abstract
The application provides application of a LuPDH-E1beta1 gene in regulating plant fatty acid synthesis, and after overexpression of the LuPDH-E1beta1 gene in plants, the amount of plant fatty acid synthesis can be increased. The application also provides application of the LuPDH-E1beta1 gene in regulating plant salt tolerance and drought resistance, and after overexpression of the LuPDH-E1beta1 gene in plants, the salt tolerance and drought resistance of a PDH-E1beta1 gene deletion plant can be increased. Through exploration of the function of the LuPDH-E1beta1 gene in plant seed oil metabolism and response to abiotic stress, the application of the LuPDH-E1beta1 gene in regulating plant fatty acid synthesis and salt tolerance and drought resistance is given, and a blank in the application of the LuPDH-E1beta1 gene in genetic engineering is filled.
