Tests for differential gene expression were conducted on the six pairwise comparisons between the four analyzed genotypes. (A) The transcriptomes of primary roots (2–4 cm long) of 3.5-d-old seedlings of two inbred lines (B73 and Mo17) and their reciprocal hybrids were compared. (B) The estimated total number of differentially expressed genes (i.e., m1; dark gray) and the number declared to be differentially expressed while controlling the false discovery rate (FDR) at 5% (light gray) are shown.
