Transcriptome analysis of a heat-resistant jujube cultivar response to high temperature stress
We found a heat-resistant jujube cultivar in our previous study, but the molecular mecanism of heat-resistantance remained investigated. In the current study, we made this seedlings of jujube cultivar to be under heat stress (45°C) for 0, 1, 3, 5 and 7 days respectively. After checking the phenotypic and physiological features, the leaf samples (HR0, HR1, HR3, HR5 and HR7) were collected accordingly. RNA-seq transcriptome comparisons were performed, showing that 2266, 4907, 6120 and 2894 differentially expressed genes (DEGs) were identified among HR1 vs. HR0, HR3 vs. HR0, HR5 vs. HR0, and HR7 vs. HR0 respectively. Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses of the DEGs from these comparisons. it revealed that a series of biological processes involved in photosynthesis, protein processing in endoplasmic reticulum and metabolism, suggesting that lowering or upregulating these processes may contribute to improved heat resistance in this jujube cultivar. Overall design: Transcriptome analysis for a jujuebe heat-resistant cultivar under heat stress,in triplicate, using Illumina HiSeq X-ten.
