Figure 8. TPS10 plants grow similarly to WT plants both alone and in competition, and do not affect their neighbors’ growth differently than WT competitors (mean ± SEM, n = 10).

Rosette diameter (A-B) and stalk length (C-D) of plants grown individually (left panels) were greater than for plants grown in competition (right panels) for all lines (see statistical analyses in Table S5), but differed little between either of two independent lines of TPS10 and WT. Within competing pairs, neither rosette diameter nor stalk length was affected by neighbor identity (Table S5). Line 10-4 had smaller rosettes than WT or TPS10 line 10-3 on day 34 post-germination, when grown in competition: **corrected P-value < 0.01 in a Wilcoxon rank-sum tests following a significant result (corrected P = 0.0024) in a Kruskal-Wallis test among lines; ns, not significant. The Holm-Bonferroni method was used to correct for 2-4 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).
