Variable amino acids detected in the PVY CP epitope sequences of PVY isolates obtained from the curated Descriptions of Plant Viruses database (http://www.dpvweb.net/).

aDistribution of the epitope in PVY strain groups. O, C and N refer to the PVY strain groups PVYO, PVYC, and PVYN, respectively.bSubstitution of the highlighted residues (bold, underlined letters in italic) for alanine in the epitope sequence shown in the uppermost line abolished detection of the protein by the MAb. The bold and underlined residues in other sequences represent natural variability of the epitope sequence in PVY isolates.cn indicates the number of PVY CP-encoding sequences analyzed.Variable amino acids detected in the PVY CP epitope sequences of PVY isolates obtained from the curated Descriptions of Plant Viruses database (http://www.dpvweb.net/).
