Fig. 2From: Intra-species recombination among strains of the ampelovirus Grapevine leafroll-associated virus 4Multiple sequence alignment of the (a) 5′ and (b) 3′ nontranslated regions of GLRaV-4 strains. Asterisk (*) indicates conserved residues. The conserved nt at the 5' and 3' ends is highlighted. The alignment was adjusted manually and gaps (shown as '-') introduced for optimal alignment of sequencesBack to article page
