Enrichment results of genes with allele-specific expression. (A) SNVs in genes annotated with ontology term defense response (GO:0006952). (B) SNVs in genes annotated with ontology term UDP-glycosyltransferase activity (GO:0008194). (C) SNVs predicted to have high functional impact. In all cases, note the excess of SNVs with exclusive expression of the reference allele (horizontal line at $\mathrm{{\rm Y}}=1$). (D) Underrepresentation of single-copy genes among those with ASE (odds ratio < 1); overrepresentation of core genes, conserved in Liliopsida (odds ratio > 1). Multiple points for the same genotype indicate different internodes.
