Expression pattern of CpC3H3 in wintersweet. A, relative expression of CpC3H3 in various tissues of wintersweet; B, expression pattern of CpC3H3 in flower developmental stages; C, relative expression of CpC3H3 in leaves in response to 20% PEG after 0 h, 2 h, 6 h, 12 h, 24 h. FMS, flower meristem formation stage; SDS, sepal primordium deferential stage; PDS, petal primordium deferential stage; StDS, sepal primordium deferential stage, PiDS, Pistil primordium deferential stage; AtDS, anther developmental stage; OvDS, ovule developmental stage; S1, flower bud stage; Stage 2, petal-display; Stage 3, initiating bloom; Stage 4, bloom; Stage 5, early-withering, and Stage 6, late-withering. The * and ** in fig. 4C indicate a significant difference from 0 h at p < 0.05 and p < 0.01, respectively, as determined by the Student t-test. Mean values followed by the same letter are not significantly different according to LSD multiple range test in fig. 4A and Games-Howell test in fig. 4B (P ≤ 0.01) respectively. The value of each bar represents mean ± SE (n = 3) of three replicates
