Extended Data Fig. 2: Upregulation of ST2a expression is mediated by PIFs and MYCs in response to low R:FR ratio and wounding, respectively.
From: A light-dependent molecular link between competition cues and defence responses in plants
a, In a pif4pif5pif7 triple mutant, which does not activate morphological responses to low R:FR ratios, the transcription of ST2a was normally upregulated by mechanical wounding, but not at all by supplemental FR radiation. GxL indicates the significance of the genotype x light interaction term in wounded plants (two-way ANOVA), and different letters indicate significant differences between means (Tukey). b, Effect of FR supplementation on ST2a expression in multiple pif mutants. Different letters indicate significant differences between genotype means in plants exposed to FR. c, Effect of mechanical wounding on ST2a expression in multiple myc mutants. In the wounding treatments, rosettes were harvested 4 h after being mechanically damaged (see Methods). Genotype effects in b and c were tested using one-way ANOVA; different letters indicate significant differences between genotype means (Tukey test). Bars indicate means; thin bars = 1 SE; n = 4 (a) or 3 (b, c) biological replicates (small open circles).
