Supporting information of genome biology and evolution of mating type loci in four cereal rust fungi

Sex in animals and some plants is determined by sex chromosomes. In fungi,
mate compatibility is determined by mating type (MAT) loci, which share
some features with sex chromosomes including recombination suppression
around heterozygous loci. Here, we study the MAT loci in fungal pathogens
from the order Pucciniales, which cause rust diseases on many economically
important plants, including wheat and oats. We show that one of the MAT
loci is multiallelic, while the other is biallelic in most cases. The
biallelic locus shows strong signs of recombination suppression and
genetic deterioration with an increase in the number of transposable
elements and gene deserts surrounding the locus. Our findings on the
genome biology of MAT loci in four economically important pathogens will
improve predictions on potential novel virulent isolates that can lead to
large-scale pandemics in agriculture. This dataset contains data related
to the study, including data on geneological analysis, alignments of HD,
Pra, STE3.2-1, and mfa genes, dS value matrices, TE annotation files, and
other TE study-related data, and data related to RNA expression
analysis.
