Hey everyone!

I've attached this picture available at:
Culbertson and Leeds. Looking at mRNA decay pathways through the window of molecular evolution. Current Opinion in Genetics & Development. 13(2), pp. 207-214

http://www.sciencedirect.com/science/article/pii/S0959437X03000145

The thing I'm confused about is that in the yeast diagram, it seems that there are no introns in the gene. Is this picture just a bit unclear, or don't yeast have introns?

Thanks!

Oops! It's meant to read S. cerevisiae, and the year the paper was published was 2003!

Yes, some yeast genes do have introns.

There are a couple of sources for a list of yeast genes with introns:

YeastMine has template searches that will allow you to find intron-containing genes
SGD's download page for genomic locations: each genomic feature has an entry in the file chromosomal_feature.tab. The file intron_exon.tab states information on the introns contained by loci.
Ares Lab Intron Site: contains information about yeast introns, maintained by Manny Ares' lab at UC Santa Cruz.
