Expression patterns of the 22 BcWRKY s under abiotic stresses. Pak-choi plants were subjected to ABA, cold, heat, high salinity, and osmotic treatments, respectively. The 22 stress-inducible BcWRKYs were significantly expressed in response to multiple abiotic stresses in the leaves and their transcript levels were quantified against BcGAPDH transcript levels using 2–ΔΔCT, ΔΔCT = ΔCT (treated sample) − ΔCT (untreated sample), ΔCT = CTtarget − CT BcGAPDH .
