Fig. 5From: Contrasting transcriptional responses of PYR1/PYL/RCAR ABA receptors to ABA or dehydration stress between maize seedling leaves and rootsTranscriptional response of ZmPYLs (a), ZmPP2C (b) and ZmSnRK2 (c) to polyethylene glycol (PEG) in maize primary roots. The root system of 15-day-old seedlings was subjected to 20 % PEG for 0 (control), 0.5, 1, 2, or 3 h. Gene expression was measured by quantitative real-time PCR. The results are the means of three biological replicates of four primary roots, each ± SEBack to article page
