From: FRESCo: finding regions of excess synonymous constraint in diverse viruses
FRESCo identifies putative novel RNA structural elements in diverse viral genomes. For each virus, we show a plot of excess synonymous constraint (top) and the putative RNA structure of an SCE (bottom). For each RNA structure, we color base pairs according to the synonymous substitution rate at a single-codon resolution. We highlight with black rectangles the SCEs for which the structure is displayed in (A) the potato virus Y polyprotein ORF, (B) the turnip mosaic virus polyprotein ORF, (C) the cucumber mosaic virus gene VP3a, (D) the foot-and-mouth disease virus polyprotein ORF, (E) the infectious bursal disease virus polyprotein, (F) the infectious bursal disease virus polymerase.
