Phenotypes of the control (ZH17), TH1:: CPB1 and DEP1:: CPB1 transgenic plants. (a) Plant architecture comparison of the control, TH1:: CPB1 and DEP1:: CPB1 plants. (b) Grain size comparison of the control, TH1:: CPB1 and DEP1:: CPB1 seeds. (c–d) Real‐time PCR analysis of CPB1/D11 expression in the leaf blades and young panicles of the control, TH1:: CPB1 and DEP1:: CPB1 plants. (e) Grain length comparison of the control, TH1:: CPB1 and DEP1:: CPB1 seeds. (f) Grain width comparison of the control, TH1:: CPB1 and DEP1:: CPB1 seeds. (g) Grain thickness comparison of the control, TH1:: CPB1 and DEP1:: CPB1 seeds. (h): Grain number per panicle among the control, TH1:: CPB1 and DEP1:: CPB1 plants. (i): 1000‐grain weight comparison of the seeds from the control, TH1:: CPB1 and DEP1:: CPB1. (j): Grain yield per plant among the control, TH1:: CPB1 and DEP1:: CPB1 plants. Scale bars (a) 20 cm and (b) 2 mm. Values in (e–h) are means ± SD (n = 20). Two‐tailed Student's t‐tests were performed between the control and TH1:: CPB1, and control and DEP1:: CPB1, respectively (*P < 0.05, **P < 0.01, NS, not significant).
