Abstract

The invention relates to the technical field of plant genetic engineering, in particular to the application of a cucumber glutaredoxin gene CsGRX4 and its botrytis susceptibility. The invention finds that a cucumber glutaredoxin gene CsGRX4 is infected with the corresponding pathogenic fungus Botrytis cinerea, and its overexpression can obviously improve the susceptibility to the pathogenic fungus Botrytis cinerea. After quantitative inoculation of Botrytis cinerea spore suspension, the lesion area of ​​the transgenic lines overexpressing CsGRX4 was significantly larger than that of the wild-type control. The above results indicated that the overexpression of cucumber glutaredoxin gene CsGRX4 in Arabidopsis increased the transgenic Arabidopsis) susceptibility to the pathogenic fungus Botrytis cinerea.

Description

technical field

[0001] The invention relates to the technical field of plant genetic engineering, in particular to the application of a cucumber glutaredoxin gene CsGRX4 and its botrytis susceptibility. Background technique

[0002] In vegetable production, plant fungal diseases have always been an important factor limiting the improvement of vegetable yield and quality. The response of vegetable crops to fungal infection can be divided into disease resistance or susceptibility. Some key genes or transcription factors play a very important role in pathogen infection and defense responses against pathogens. When plants are susceptible to disease, pathogenic bacteria induce up-regulation of the expression of some key genes or inhibit the defense response of plants through infection, including the regulation of signaling pathways closely related to disease defense responses and the regulation of disease resistance gene expression, thereby causing the occurrence of diseases.
