Thus, it resembles RNA 2 of cucumber mosaic virus (CMV) strains Q and Fny (62% identical to both), brome mosaic virus (42% identical) and cowpea chlorotic mottle virus (40% identical). In comparisons between amino acid sequences, three different regions of similarity could be distinguished. These were the central part (amino acids 224 to 757 for V-TAV), which was most similar among the four viruses, and the N and C ends; sequences conserved among RNA polymerase species were found in the C half of the central part. Hydrophobicity patterns, and distributions of acidic and basic amino acids in the proteins encoded by V-TAV RNA 2, Q-CMV RNA 2 and Fny-CMV RNA 2 were very similar except at the extreme ends of the molecules. Structures that have been reported to act as regulatory signals for minus- and plus-strand synthesis were found in the 5′ and 3′ non-coding regions of the RNA., UL https://www.microbiologyresearch.org/content/journal/jgv/10.1099/0022-1317-72-4-779
