The invention discloses a method for applying an air-dried sludge microbial agent to resist low temperature of tall fescue. It includes a 100-fold dilution of Pseudomonas stutzeri + Trichoderma reesei + Streptomyces flavum or a 200-fold dilution of Pseudomonas stutzeri + Trichoderma reesei + Streptomyces flavum. The development results of the present invention show that the application of the composite microbial agent of Pseudomonas stutzeri, Trichoderma reesei and Streptomyces griseus can significantly increase the tall fescue plant height, aboveground biomass and chlorophyll content, and improve its cold resistance. The greening of tall fescue after the application of microbial agents was about 5 days earlier than that of the blank control, and the comprehensive index of lawn appearance after turning green was also significantly higher than that of the blank control. This fully demonstrates the application potential of the composite microbial agent in practice.

The invention relates to the technical field of plant genetic engineering, in particular to the application of GLK7 protein and its coding gene in plant drought resistance. The present invention found that after the overexpression of the GLK7 gene, the wilting degree of the leaves of the transgenic plants was lighter than that of the wild type under drought treatment conditions, and the chlorophyll content was higher than that of the wild type, indicating that the overexpression of the gene can significantly improve the drought resistance of plants. The new variety provides genetic resources and provides a theoretical basis for elucidating the molecular mechanism of GLK7 transcription factor in plant drought stress response.
