Transcriptional responses of ABA core signaling components to ABA, showing time- and dose-dependent patterns in maize leaves. The treatments were similar to those in Fig. 2. The topmost largest expanded leaves were sampled from the corresponding treatments. Gene expression of ABA receptors PYR/PYL/RCAR (a, d), PP2C (b, e) and SnRK2s (c, f) was measured by real-time PCR. The results are the means of three biological replicates of four leaves, each ± SE
