Summary of the presence or absence of IPO323 genes across all chromosomes. Gene presence (dark colors) or absence (translucent) for each re-sequenced isolate is shown for all annotated genes from the reference isolate IPO323. Each row in the figure represents one annotated gene, while each column represents one isolate. There are 13 columns in each panel; the number at the top (in the gray bar) indicates the chromosome. Isolates are ordered from left to right, from earliest to latest year of sampling. Isolates in the same color were sampled during the same year. (A) The core chromosomes of Z. tritici possess most of their annotated genes with very few large deletions. (B) The accessory chromosomes possess several large segmental gene deletions, many of which indicate that entire chromosomes are missing or significantly altered in structure from the reference genome.
