Additional file 23: of Maize RNA PolIV affects the expression of genes with nearby TE insertions and has a genome-wide repressive impact on transcription

Distribution plots of siRNA loci occupancy. The plots of siRNA loci coverage in flanking regions of subgenome genes, further split between homeologs and single copy genes of each subgenome, confirm that genes of the recessive subgenome 2 are preferentially siRNA-enriched in the upstream region, without differences between retained homeologs and single copy genes.
