TPS10 plants produce similar numbers of buds, flowers, and seed capsules as the wild type when grown alone or in competition and do not affect their neighbors’ reproduction differently than wild-type competitors (mean ± sem, n = 10). Plants of all lines produced more buds and flowers (A and B) and ripe and unripe seed capsules (C and D) when grown individually (A and C) versus in competition (B and D), but reproductive measures differed little between either of two independent lines of TPS10 and the wild type; within competing pairs, none of these parameters were affected by neighbor identity (statistical analyses in Supplemental Table S6). Different letters indicate significant differences (corrected P < 0.05) in Tukey’s HSD mean-separation tests between lines conducted after a significant effect of line (corrected P < 0.05) in an ANOVA minimal model. The Holm-Bonferroni method was used to correct for two to four tests of each data set (effect of line within individuals or competing pairs, effect of neighbor within competing pairs, effect of competition, and post hoc pairwise tests). ns, Not significant, v., versus; WT, wild type.
