  • B73 and PH207 RNA-seq reads were mapped to both their cognate genome and the reciprocal genome, and expression was summarized as read counts in each of the mapping scenarios. Tissues included in this analysis were leaf blade, root cortical parenchyma, root stele, germinating kernel, root tip, and whole seedling.

  • a The total number of genes in each genotype are 39,301 (B73) and 40,557 (PH207).
