Magnitude of significant transcript accumulation differences observed between parental accessions H. annuus cmsHA89 and H. petiolaris Pet2152 (A, C) and between parental alleles within F1 hybrids (B, D). Horizontal axes show the log₂ fold-change in transcript accumulation associated with a shift from H. annuus to H. petiolaris, thus positive values indicate relatively higher levels of transcript accumulation in H. petiolaris (A, C) or of the H. petiolaris allele within the F1 (B, D). Vertical axes show the number of contigs showing statistically significant differences between accessions or alleles (adjusted p-value < 0.01). Panels A and B show the distribution of all significant results, while panels C and D show only contigs from the reference dataset that show significant differences in transcript levels both between accessions and between alleles.
