AI Technical Summary
Technical Problem
Existing technologies are insufficient to effectively enhance plant resistance to abiotic and biotic stresses, especially in the areas of drought, salt stress, and oxidative stress, and the application of ascorbate peroxidase (APX) in plant defense systems is inadequate.
Method used
Provide the Spartina alterniflora ascorbate peroxidase SanAPX11 gene and its encoded protein, and express them in plants through recombinant expression vectors (such as pTRV2-SanAPX11 and pRI101-AN-GFP-SanAPX11) to enhance plant stress resistance.
Benefits of technology
It improved the plant's tolerance to drought, oxidation and salt stress, reduced oxidative damage, and enhanced the plant's stress resistance.

Abstract
The invention belongs to the technical field of plant genetic engineering, and particularly relates to a spartina anglica ascorbic acid peroxidase SanAPX11 gene and application, the nucleotide sequence of the SanAPX11 gene is shown as SEQ ID NO.1, and the amino acid sequence of protein coded by the SanAPX11 gene is shown as SEQ ID NO.2. After the SanAPX11 gene is transferred into a cell in the form of a plant expression vector, the SanAPX11 gene is expressed in a plant cell, so that the stress resistance of the plant, particularly drought stress resistance, oxidative stress resistance, salt stress resistance and the like, can be improved.
