    Snippet: We therefore extended the bioinformatics analysis using all eight currently available 326 torovirus genome sequences ( Figure 9 ). Since the U2 ORF overlaps ORF1a, leading to 327 constraint on dS, the dN/dS analysis is not appropriate for U2. MLOGD analysis 328 indicated that the U2 ORF has a higher coding potential than the corresponding part 329 of ORF1a ( Figure 9 ). Overlapping genes are thought mainly to evolve through 330 "overprinting" of .....

MLOGD analysis 328 indicated that the U2 ORF has a higher coding potential than the corresponding part 329 of ORF1a ( Figure 9 ). Overlapping genes are thought mainly to evolve through 330 "overprinting" of an ancestral gene by the de novo gene (25). The de novo gene 331 product is often an accessory protein and often disordered (26). Interestingly, the 332 fragment of pp1a encoded by the region of ORF1a that is overlapped by U2 has no 333 tblastn (27) The copyright holder for this preprint (which was not peer-reviewed) is the . https://doi.org/10.1101/296996 doi: bioRxiv preprint probability that the observed level of conservation would occur by chance is p = 6.5 x 344 10 −40 . 345
