Study on cucumber salicylic acid transcriptome

Cucumber (Cucumis sativus L.) is a plant of Cucurbitaceae. As a main vegetable crop in China, cucumber is easily infected by some pathogens, which causes serious losses to cucumber production. In plants, salicylic acid (SA), as an endogenous signal molecule, can induce hypersensitivity (HR) and systemic acquired resistance (SAR) to improve plant disease resistance, and also induce the expression of some related disease resistance genes in plants.Therefore, in this experiment, the transcriptome sequencing of cucumber leaves treated with SA for 12 hours was carried out by Illumina sequencing, and the changes of transcription level induced by SA in cucumber were analyzed, and the genes related to SA signal transduction were obtained.
