AI Technical Summary
Technical Problem
The prior art has not yet disclosed whether mitochondrial GPAT is involved in plant keratin synthesis and regulating the development of trichomes, and there is a lack of effective methods to regulate plant keratin thickness and trichome numbers.
Method used
By inhibiting the expression of mitochondrial GPAT1 gene and mitochondrial GPAT2 gene in Arabidopsis, the thickness and number of stratum corneum of plant are reduced, thereby cultivating transgenic plants with thin stratum corneum and low-density stratum corneum.
Benefits of technology
The regulation of plant stratum corneum thickness, trichome number, water metabolism and drought tolerance is achieved, and new methods are provided for the cultivation of new plant varieties.

Abstract
The invention relates to the technical field of gene engineering, in particular to application of a mitochondrial GPAT1 gene and a mitochondrial GPAT2 gene in regulating and controlling the thickness of a plant cuticle. The invention discovers that the mitochondrial GPAT1 gene and the mitochondrial GPAT2 gene have the effects of regulating and controlling the thickness of the cuticle, the number of hairy bodies, water metabolism and drought tolerance of the plant for the first time. When the mitochondrial GPAT1 gene and the mitochondrial GPAT2 gene are deleted, the synthesis of a cutin monomer is blocked, so that the cuticle of the double-mutant gpat1gpat2 of the arabidopsis thaliana is thinner than that of wild arabidopsis thaliana, the structure of the cuticle is damaged, the development of hairy bodies is blocked, and meanwhile, the water loss rate of seedlings of the double-mutant gpat1gpat2 of the arabidopsis thaliana is lower than that of the wild arabidopsis thaliana. Therefore, the mitochondrial GPAT1 gene and the mitochondrial GPAT2 gene can be used for regulating and controlling the thickness of the cuticle, the number of hairy bodies, water metabolism and drought tolerance of the plant.
