Mating type locus comparison (A) Structural organization of the MAT locus in F. graminearum and F. neocosmosporiellum. Genes that occur in both the MAT1-1 and MAT1-2 idiomorphs in heterothallic species occur together at a single MAT locus in these two homothallic species. In most ascomycetes, the MAT locus is flanked by APN2 (encoding a DNA lyase) and SLA2 (encoding a cytoskeletal protein), which are convergently transcribed toward the MAT genes. RNA-seq read coverage for MAT and flanking genes at S4 (ascus development stage) is plotted for both DNA strands (blue and green) with genome coordinates. Direction of transcription is the same for genes depicted as blue bars and opposite that of genes depicted as green bars. (B) MAT gene expression during perithecium development. Expression levels are presented as log₂[RPKM+1]; Blue lines: F. graminearum, Red lines: F. neocosmosporiellum.
