Global view of gene expression in hyphae, conidia, germinating conidia, and microsclerotial formation stages MS1-4. Seven concentric circles from inside to outside represent fungal stages CO, HY, GC, MS1, MS2, MS3 andMS4, respectively. Color representation (from black to red) illustrates the expression level (FPKM, fragments per kilobase of transcripts per million mapped fragments) of each transcript in each sample. The red and green colored bars in the gray circle represent genes significantly up- or down-regulated during microsclerotia development compared to the CO stage (q value <0.05), respectively. Each chromosome is shown by the number of the first outer circle, which represents the V. dahliae strain VdLs.17 scaffold number assigned by the Broad Institute. Red ovals represent the four LS regions in the V. dahliae, marked as LS1, 2, 3, 4. Numbers under the outer circle correspond to the respective supercontigs of the V. dahliae genome.
