Uncovering de novo gene birth in yeast using deep transcriptomics

Genome-wide studies of de novo genes have tended to focus on genomic open reading frames (ORFs). Here, Blevins et al. use deep transcriptomics and synteny information to identify de novo transcripts in the yeast Saccharomyces cerevisiae, many of which are expressed from the alternative DNA strand.

In organisms with a large genome, intergenic and intronic regions provide plenty of raw material for new transcriptional events to occur, but little is know about how de novo transcripts originate in more densely-packed genomes. Here, we identify 213 de novo originated transcripts in Saccharomyces cerevisiae using deep transcriptomics and genomic synteny information from multiple yeast sp
