a–e Phenotype (a), panicle number (b), grain number per panicle (c), 1000-grain weight (d), yield per plant (e) and N use efficiency (NUE) (f) in WT, stp28-3, CSNC, CSHap.C and CSHap.H at mature stage under LN or HN supply in Nanjing in 2023. Scale bar = 3.5 cm in (a). Four independent CSHap.C and CSHap.H complementation lines were tested in this study. Accordingly, in (b–f), boxes show the first quartile, median, and third quartile; whiskers show the minimum and maximum values. n = 7 individual plants for WT, stp28-3, and CSNC; n = 28 individual plants for CSHap.C and CSHap.H. Different letters indicate significant differences at P < 0.05 according to one-way ANOVA and Tukey’s HSD test. g, h Phenotype, tiller number and grain yield per plant in MH63 (Ming Hui 63, containing OsSTP28Hap. C allele) and stp28MH63 lines (g), or in GLA4 (Guang Lu Ai 4, containing OsSTP28Hap. H allele) and stp28GLA4 lines (h) under LN or HN supply. Scale bar = 20 cm in (g, h). In (g, h), boxes show the first quartile, median, and third quartile; whiskers show the minimum and maximum values. n = 11 individual plants. Different letters indicate significant differences at P < 0.05 according to one-way ANOVA and Tukey’s HSD test.
