![]() Finally, we identify a gene that displays a differential number of introns in a repetitive DNA region. Some genes preferentially lose introns and a large proportion of intron losses occur in the middle of genes (so called internal intron loss). We observe a predominance of intron loss over gain and identify a relatively slow intron loss rate in Cryptococcus. To ascertain mechanisms of intron gain and loss, we compared five relatively closely related genomes from the yeast Cryptococcus. However, because of the deep divergences involved in these comparisons, little is understood about how these changes occur, particularly in the case of intron gain. Genome comparisons across deep phylogenetic divergences have revealed that spliceosomal intron gain and loss are common evolutionary events.
