Phenotypic observation of wild type and hcc1. A WT and hcc1 at maturity. B The phenotype of WT and hcc1 leaves at maturity. Scale bar in A = 20 cm and in B = 2 cm. C Comparison of chlorophyll a and chlorophyll b contents between WT and hcc1 at mature stage. Mean and SD were obtained from three independent experiments. Comparison of plant height (D), number of tillers (E), kernels per spike (F), 1000-grains weight (G), and seed setting rate (H) between WT and hcc1 respectively. Data presented in D–G were the average of n = 10 plants. Statistical analysis was performed using two-tailed Student’s t-test, *, ** and ***indicate p < 0.05, p < 0.01 and p < 0.001 respectively
