a–f Three knockout lines (KO1, KO2 and KO3) with loss-of-function mutations in ZmEXPB15 had smaller kernels than the corresponding wild-type (WT1, WT2 and WT3) in a C01 inbred background. g–i Quantitative analysis of the hundred kernel weight (g), kernel length (h) and kernel width (i) in three knockout lines. j–o Three ZmEXPB15 overexpressing lines (OE1, OE2 and OE3) had larger kernels than their corresponding non-transgenic lines (NT1, NT2 and NT3) in a B104 inbred background. p–r Quantitative analysis of the hundred kernel weight (p), kernel length (q) and kernel width (r) in three overexpressing lines. s Mature kernels of four F1 hybrids derived from overexpression line OE1 and the corresponding control NT1 by crossing to four elite inbred lines (Zheng58, 6WC, Chang7-2, Dan340). t Quantitative analysis of the HKW of four F1 hybrids same as (s). Number on the bottom of each column is the sample size. Values in (g–i, p–r, t) are means ± s.d., and the significance is estimated by the one-way ANOVA. *P < 0.05, **P < 0.01, ***P < 0.001. ns, non-significance. Scale bar = 1 cm in (a–f, j–o, s).
