Tomato glutaredoxin SlGRXC9 gene and application thereof

Abstract

The invention discloses a tomato glutaredoxin SlGRXC9 gene and application thereof.The tomato glutaredoxin SlGRXC9 gene is obtained from tomatoes for the first time, SlGRXC9 is knocked out from tomato MT (micro-Tom) through an agrobacterium tumefaciens-mediated method for functional verification, and it is obtained that deletion of the SlGRXC9 gene can induce a tomato plant to be sensitive to cold stress; meanwhile, dwarfing symptoms such as plant height reduction, leaf length reduction and leaf width reduction appear, which shows that the SlGRXC9 plays an important role in regulating tomato development and responding to low-temperature stress.

Description

technical field [0001] The invention belongs to the field of biotechnology, in particular to tomato glutaredoxin SlGRXC9 Genes and applications. Background technique [0002] Low temperature stress seriously affects the quality and yield of horticultural crops such as tomato, and has become one of the bottlenecks restricting the development of facility agriculture in my country. With the continuous development of genetic engineering technology, genes related to tomato response to low temperature stress can be precisely edited through genetic engineering technology, and the phenotypic changes of gene-edited lines to low temperature treatment can be studied. If the gene-edited plants are sensitive to low-temperature treatment, the gene is overexpressed in the plant; if the gene-edited plants have enhanced tolerance to low-temperature treatment, they are directly applied to production. The invention is committed to improving the resistance of vegetable crops under adverse env...
