Application of GhDBB28 gene in regulating salt tolerance of upland cotton plants
By silencing the GhDBB28 gene, the salt stress tolerance of upland cotton plants was regulated, resulting in growth restriction and sensitivity of the plants under salt stress, thus solving the problem of regulating salt tolerance in cotton plants.

AI Technical Summary
Technical Problem
Existing technologies are insufficient to effectively regulate the salt stress tolerance of cotton plants, thus affecting their growth and development.
Method used
Silencing the GhDBB28 gene reduces the activity of the antioxidant system in upland cotton plants. Silencing the GhDBB28 gene using recombinant plasmids or recombinant Agrobacterium can increase the salt sensitivity of upland cotton plants.
Benefits of technology
Under salt stress, the transgenic upland cotton plants exhibited limited growth, with some leaves turning yellow, stunted and weak plants, reduced chlorophyll content and antioxidant enzyme activity, and increased cell damage, demonstrating their sensitivity to salt stress.

Abstract
The application relates to the field of agricultural transgenic technology, and particularly discloses GhDBB28 application of a gene in regulating salt tolerance of upland cotton plants, the gene GhDBB28 The nucleotide sequence of the gene is shown as SEQ ID NO. 1; silencing the gene GhDBB28 increases the salt sensitivity of the upland cotton plants. The application reduces the activity of an antioxidant system in the upland cotton plants by silencing the gene GhDBB28 , so that the plants are more sensitive to salt stress, and a scientific basis is provided for constructing a transgenic upland cotton plant with new salt-sensitivity.
