Mitoviruses replicate in mitochondria of their host fungi. They have small RNA genomes that encompass a single ORF encoding the viral RdRp. Since UGA codons encode Trp in fungal mitochondria, the RdRp ORF of a typical mitovirus includes multiple UGA codons. In some mitoviruses, however, the ORF has no such codons, suggesting that these particular viruses may be under selective pressure to exclude them. In this report, new evidence is presented that host fungi whose mitoviruses have no or few UGA ...[more]
