| Summary: | Salt stress is a main factor that harms the growth of horticultural crops. To reveal the molecular mechanism of salt stress, we conducted transcriptome sequencing on samples of pomegranate (Punica granatum ‘Fuanyihao’) roots subjected to salt stress at different time periods and control conditions. A total of 23,798 genes have been identified. Furthermore, 3366 genes, including 758 transcription factors (TFs), showed obvious differential expression in salt-tolerant or salt-sensitive genotypes. There is a certain quantity of differentially expressed genes (DEGs) identified under salt treatment at different time periods. Among them, many encoding TFs were found, such as bHLH-, NAC-, MYB-, ERF-, and WRKY- encoding genes. These DEGs were related to multiple pathways, mainly including the MAPK pathway, Glucosinolate biosynthesis, Cutin, etc. In these enriched pathways, plant hormone signal transduction and MAPK pathway-plant were the most notable. In total, abundant salt-stress response DEGs and pathways between pomegranate root systems treated at different times were identified, which promotes the understanding of salt-stress response mechanisms and are beneficial for improving a salt-resistance molecular breeding in pomegranate. |
