Evidence of mRNA-Mediated Intron Loss in the Human-Pathogenic Fungus Cryptococcus neoformans

Abstract excerpt

Introns are a defining feature of eukaryotic genomes, though the mechanism of intron gain or loss is not well understood. Reverse transcription of mRNA followed by homologous recombination with the genome has been posited as a mechanism of intron loss, though little direct evidence of recent loss events has been described to support this model. We find supporting evidence for an mRNA-mediated mechanism of loss...
