Abstract
Long non-coding RNAs (lncRNAs) are key regulatory elements that play important roles in plant development as well as stress responses in plants. A genome-wide analysis of lncRNA expression in salt tolerant (Xiaoyan60) and salt sensitive (Lumai21) wheat cultivars under salt stress conditions was performed. We identified a total of 746 differentially expressed lncRNAs under salt stress that 675 were expressed in Xiaoyan60 and 592 in Lumai21. Gene ontology enrichment analysis indicated that differentially expressed genes were enriched in biological process, cellular component and molecular function. KEGG (Kyoto Encyclopedia of Genes and Genomes) analysis revealed that the distinct lncRNAs were involved in salt tolerance-related pathways, including plant hormone signal transduction and 27 other pathways. We identified lncRNAs that were significantly upregulated (i.e., lnc_521, lnc_593 and lnc_743) in Xiaoyan60 when compared with Lumai21 after salt stress. These results indicated that lncRNAs were involved in salt tolerance, and our findings provided an important insight regarding wheat adaptation to salt stress.
