Correlation RNA-Seq and RT-PCR data. The relative log2FC for known as well as novel candidate genes (Additional file 1: Table S4) to Actin1 (GRMZM2G126010) are given for corresponding genes. The RNA-Seq log2FC represents the median log2FC relative to Actin1 across all statistical approaches. The log2FC of corresponding genes for B73 at 300 μM (dark green), B73 at 10 μM (light green), Mo17 at 300 μM (red), Mo17 at 10 μM (orange) is displayed. The Pearson correlation coefficient (R2) as well as a linear regression line with confidence interval is indicated.
