Pathways enriched for ODO1 ChIP‐seq binding. (a) Gene loci encoding enzymes contributing to phenylalanine biosynthesis and phenylpropanoid pathways leading to production of volatiles (emitted FVBPs in red text). Squares represent individual loci for a gene encoding a protein that is active in a particular pathway or that catalyzes the conversion of depicted metabolites, with red squares representing ODO1‐bound loci. (b) Hypergeometric p value for enrichment of ODO1‐bound genes among those belonging to FVBP and phenylpropanoid pathways in petunia (Patrick et al., 2021). Genes were assigned to the shikimate/phenylalanine pathways, the general phenylpropanoid reactions (PAL, C4H, and 4CL genes), the volatile benzenoid and phenylpropanoid branches (C₆‐C₁ and C₆‐C₂), and monolignol/eugenol branch (C₆‐C₃).
