Distributions of genomic elements of tomato, eggplant and turkey berry on tomato genome. A1, The log2-transformed tomato gene density (blue histogram ring) along the tomato chromosomes (ch, outer circle). Gene density represented as number of genes per 500 kb (non-overlapping, window size = 500 kb), and the log2-transformed gene density ranged from 0.00 to 6.50. A2 and A3, The log10-transformed average depth of RNA-Seq reads from eggplant (A2, green histogram ring) and turkey berry (A3, red histogram ring). We used the 500kp non-overlapping sliding windows to calculated the average depth, and the log10-transformed average depth ranged from 1.50 to 6.50. B1, Tomato resistance genes. Colors correspond to the gene product types indicated in the center of the diagram. B2 and B3, resistance genes of eggplant (B2 ring) and turkey berry (B3 ring). The square root of the number of resistance genes per tomato homolog (BLASTX hits) ranged from 1.00 to 3.00 (for illustration purposes, the minimum was set at 0.80).
