The application discloses application of a ZmCDPK31 gene in corn drought response and belongs to the technical field of biotechnology.The application discloses the application of the ZmCDPK31 gene in corn drought response, and the CDS sequence of the ZmCDPK31 gene is shown as SEQ ID NO.2.The application knocks out the coding gene of the protein ZmCDPK31 to positively regulate the drought resistance of plants, and has a positive effect on accelerating the improvement of corn drought-resistant varieties.

This invention discloses the application of the wheat gene TaPSS2 in improving plant drought resistance, belonging to the field of functional genomics. The nucleotide sequence of the wheat gene TaPSS2 is shown in SEQ ID NO: 2. Transforming this gene into the model plant Arabidopsis thaliana can significantly improve the drought resistance of Arabidopsis. If the wheat gene TaPSS2 is transformed into wheat, rice, maize, cauliflower, and other plants, it is possible to obtain new germplasm with drought-resistant characteristics, which is of great significance for the breeding of superior crop varieties and their widespread application in production.

The invention discloses an agriophyllum squarrosum AsWUS gene, a recombinant vector and application of the agriophyllum squarrosum AsWUS gene to improvement of plant stress resistance, and relates to the technical field of plant genetic engineering. The AsWUS gene is cloned from a high-stress-resistance wild plant agriophyllum squarrosum for the first time, and experiments prove that after the AsWUS gene is over-expressed in a model plant arabidopsis thaliana, the drought tolerance and salt tolerance of the plant can be remarkably improved. Precious gene resources and effective technical means are provided for molecular breeding of crops. The AsWUS gene, the recombinant vector and the recombinant bacteria provided by the invention have good application prospects in improving drought resistance and / or salt resistance of plants.

The present application relates to the field of biotechnology, in particular to a strain CXL-18 of a layered near-melanosporum and application thereof.The strain CXL-18 of the present application can effectively promote the growth of pear trees, and also improve the drought resistance of pear trees; after the pear trees are inoculated with the strain, the plant height, stem diameter, leaf area and dry weight are all significantly higher than those of the control group without inoculation; from the appearance, the growth of the plants is obviously better than that of the control group; under the stress of moderate drought conditions, the leaf area is significantly increased by 33.50% compared with the control, and the relative water content of the leaf is significantly increased by 27.06% compared with the control; from the growth of the plants, the growth is also better than that of the control group, which shows that the strain CXL-18 has good growth-promoting ability for pear trees, can improve the drought resistance of pear trees, and can provide a new idea for the research and development of pear tree biological bacterial fertilizer.

The application discloses a planting method for relieving drought of wheat based on combined application of SiQDs seed dressing and halophilic bacillus, and belongs to the technical field of agricultural planting. The application discloses a planting method for relieving drought of wheat based on combined application of SiQDs seed dressing and halophilic bacillus, which comprises the following steps: using silicon quantum dots (SiQDs) for seed dressing treatment of wheat seeds, then planting the seed-dressed wheat seeds in soil, and applying halophilic bacillus agent during the growth of the wheat. The combined application of SiQDs and halophilic bacillus GS127 can better promote the root development of wheat under drought stress, increase the content of proline and soluble sugar in the wheat, reduce the content of malondialdehyde, enhance the drought resistance of the wheat, effectively promote the growth of the wheat, and improve the yield and water use efficiency, and therefore has excellent application potential in the production in agricultural wheat drought areas.
