Abstract

The identification of untranslated regions (UTRs), introns, and coding regions within an organism remains challenging. We developed a quantitative sequencing-based method for mapping transcribed regions called RNA-Seq in which cDNA fragments are subjected to high throughput sequencing and mapped to the genome. We applied RNA-Seq to generate a high-resolution transcriptome map of the yeast genome and demonstrated that most (74.5%) of the nonrepetitive sequence of the yeast genome is transcribed. We confirmed many known and predicted introns and demonstrated that others are not actively used. Alternative initiation codons and upstream open reading frames were also identified for many yeast genes. We also found unexpected 3' end heterogeneity and the presence of many overlapping genes. These results indicate that the yeast transcriptome is more complex than previously appreciated.
