Distributions of transcription level ratios between aneuploid and euploid plants. The log₂(aneuploid/euploid) ratios of each of 50,996 genes with an FPKM values above unity in euploids and aneuploids were plotted as a ratio distribution along each chromosome. The x axes correspond to the physical position of the genes. Each point represents a gene: red indicates the contrast of euploid vs M4B, blue indicates euploid vs Tri4B and green indicates euploid vs SegT2A. The correspondingly coloured lines track the smoothed distribution of the log₂(aneuploid/euploid) ratios. A relative change in transcript abundance of zero is designated by the ratio 0 (log₂1); a 0.5-fold increase, by 0.6 (log₂1.5); a 0.5-fold decrease, by the ratio − 1 (log₂0.5); and a 1.0-fold increase, by the ratio 1 (log₂2)
