Expression patterns of TaeIF5A1 and its upstream regulator genes (TaRAV and TaWRKY) and their Arabidopsis homologs. A–B. Expression patterns of TaeIF5A1 and its upstream regulator genes (TaRAV and TaWRKY) in the roots, stems and leaves of 2-month-old T. hispida seedlings subjected to 150 μM ABA or 20% PEG6000 treatment. C–D. Expression patterns of the AT1G13950, AT1G68840 and AT1G13960 genes in the roots and leaves of three week-old Arabidopsis seedlings subjected to 100 μM ABA or 20% PEG6000 treatment. AT1G13950, AT1G68840 and AT1G13960 in Arabidopsis are homolog to TaeIF5A1, TaRAV and TaWRKY, respectively. The relative expression level = log2 (transcription level under stress treatment / transcription level under control conditions). The error bars were obtained from multiple replicates of the real-time PCR.
