Figure 3

Combined mean transcript accumulation (count of mapped reads) for parental accessions H. annuus cmsHA89 and H. petiolaris Pet2152 plotted on the horizontal axis against mean transcript accumulation in F1 hybrid plants (vertical axis). Each point represents one of 16,312 contigs in the reference transcript set. Values on both axes are plotted on a log₁₀ scale. Dotted lines indicate the 99% confidence interval for F1 hybrid transcript accumulation predicted by the linear model: F1 transcript accumulation = SLOPE*mean parental transcript accumulation + INTERCEPT (p < 0.0001, R² = 0.98).
