Transcriptomic analysis revealed genes involved in response to drought stress in Zizyphus jujuba var. Spinosa. Transcriptomic analysis revealed genes involved in response to drought stress in Zizyphus jujuba var. Spinosa

Through transcriptome sequencing analysis, drought-resistant genes were excavated to lay a foundation for the cultivation of excellent lineage of Zizyphus jujuba var. Spinosa.There were a total of 10136 differential expressed genes were obtained by transcriptome sequencing of the two families No.1 and No.5, among which 5254 genes were up-regulated and 4882 genes were down-regulated.Several gene families related to drought resistance were found, including ERF, bZIP, MYB, WRKY, NAC, ZFP, F-box, HSP, and bHLH.There are 926 entries commented to the Go function.There are 122 metabolic pathways annotated for KEGG function.The results of PCR fluorescence quantitative verification of 19 drought-related genes were consistent with the results of transcriptome sequencing, among which 15 genes were up-regulated in No. 1 family. Overall design: Transcriptome sequencing was performed on two Zizyphus jujuba var. Spinosa families No. 1 (treatment group) and No. 5 (control group) under drought stress for 15 days.There were 3 biological replicates in each family
