Real-time qRT-PCR analysis of selected genes from the RNA-seq dataset. Total RNA was extracted from K. caspica exposed to salt stress, and real-time PCR was used to validate the changes in gene expression of putative SnRK2 (comp38192, A; comp 30500, B), PYL (comp38298, C; comp365319, D), and PP2C (comp6211, E). KcACTIN was used as the internal control. Error bars indicate standard deviations from three independent biological samples. And the fold change estimated by transcriptomic ananlysis were also illustrated in F.
