The origin and evolution of a distinct mechanism of transcription initiation in yeasts

The molecular process of transcription by RNA Polymerase II is highly conserved among eukaryotes (classic model). A distinct way of locating transcription start sites (TSSs) has been identified in a budding yeast Saccharomyces cerevisiae (scanning model). Herein, we applied genomic approaches to elucidate the origin of the scanning model and its underlying genetic mechanisms. We first identified TSSs at single-nucleotide resolution for 12 yeast species using the nAnT-iCAGE technique, which significantly improved the annotations of these genomes by providing accurate Sr boundaries for protein-coding genes. We then inferred the initiation mechanism of each species based on its TSS maps and genome sequences. We discovered that the scanning model likely originated after the split of Yarrowia lipolytica and the other budding yeasts. Species that use the scanning model showed an adenine-rich region immediately upstream of the TSS that might facilitate TSS selection. Both initiation mechanisms share a strong preference for pyrimidine-purine dinucleotides surrounding the TSS. Our results suggest that the purine is required to accurately recruit the first nucleotide, thereby increasing the chances of a messenger RNA of being capped during mRNA maturation, which is critical for efficient translation initiation during protein biosynthesis. Based on our findings, we propose a model for TSS selection in the scanning-model species, as well as a model for the stepwise process responsible for the origin and evolution of the scanning model.
