Pattern of intron gains and losses in Neurospora. (A) Phylogenetic relationship of the four Neurospora genomes in this study. (B) Classification of intron presence (1) and absence (0) for the 9495 intron sites. The number of intron sites for each pattern is indicated at the bottom of the figure. SR indicates that the intron position is located within the region of suppressed recombination of the mating-type chromosomes in N. tetrasperma, and R in the normal recombination region of the genome.
