Centromeres of Z. tritici are small and contain expressed genes. Segments (65 kb) of core chromosomes (Chr) 1 and 13 and the accessory Chr 14 and 21 are shown. The ruler indicates chromosome coordinates (Coor, in kb), and GC-content (%GC, red), centromere position determined by GFP–CenH3 enrichment (Cen, black), location of coding sequences (CDS, blue) and active or inactive transposable elements (TE, marine) are shown. Expression data [14] from pure culture (mRNA1) and in planta at 4 days post-infection (mRNA2) are also plotted (blue). Genes surrounding or overlapping the centromere are expressed to varying degrees. AT-richness and enrichment with TEs is not a characteristic of Z. tritici centromeres
