Figure 4.

Genetic rearrangements in the rcd-1 locus in Neurospora. rcd-1-1 (green) and rcd-1-2 (pink) alleles from different species are shown as cartoons in the rcd-1 locus. The extended region in pink in rcd-1-2 represents the sequence with sharp decrease in homology (or regions with lack of homology) at nucleotide level between strains of the rcd-1-1 and rcd-1-2 genotype. Percentage identities between two different genomic regions are shown between black lines delimiting the comparisons. Numbers over the rcd-1-1 allele indicate the limits of the truncated ORF in the genome of different Neurospora species and strains. Red line in the rcd-1-2 allele of Neurospora hispaniola (Nhis-8817) represents a premature stop codon. Species names are abbreviated as follows; N. africana (Nafr), N. hispaniola (Nhis), N. crassa (Ncra), N. sublineolata (Nsub), N. discreta (Ndis).
