Plant Virus Genome Is Shaped by Specific Dinucleotide Restrictions That Influence Viral Infection

mBio, 2020
The presence of CpG and UpA dinucleotides is restricted in the genomes of animal RNA viruses to avoid specific host defenses. We wondered whether a similar phenomenon exists in nonanimal RNA viruses. Here, we show that these two dinucleotides, especially
