Abstract

The mitochondrial ribosomal protein S3 (rps3) gene within the fungi is extremely diverse in location and organization, some versions of this gene have been incorporated into a group I intron, others appear to have gained large insertions, microsatellite expansions, or have been invaded by homing endonucleases. Among the ascomycetes fungi the group I intron encoded version of rps3 appears to have a rather complex evolutionary history including first the acquisition of rps3 by a group I intron (mL2449), the loss of the mL2499 intron and the establishment of rps3 as a free-standing gene, and the eventual loss of the intron derived version of rps3.
