Hemiascomycetous Yeast Spliceosomal Introns





This site contains information about a comparative approach of spliceosomal introns in Saccharomyces cerevisiae and seven hemiascomycetous yeast species of the explorating sequencing program Génolevures.

Genolevures bibliographie 25S rDNA tree

Spliceosomal introns were sought in homologues of intron carrying Saccharomyces cerevisiae genes detected in Random Sequence Tags (RSTs) from the seven related yeast species. Visual scrutinization and bioinformatic tools led to the detection of 153 putative novel yeast introns.
