dc.description.abstractThe CP gene variability among 21 olive latent virus 1 (OLV-1) isolates obtained from different hosts and locations and at different times was assessed. Amplicons obtained by RT-PCR were cloned, and at least 10 sequences from each isolate were analyzed and compared. OLV-1 sequences available in GenBank were included. The encoded CPs consisted of 270 amino acids, except those of isolates G1S and C7 (269 aa) and G6 (271 aa). Comparison of CP genomic sequences of the isolates under study showed very low values of nucleotide diversity, 0.02, and maximum nucleotide distances between (0.087) or within isolates (0.001). Although very few nucleotide sequence differences were observed among the isolates, olive isolates exhibited lower diversity (0.012). In addition, at position 158 (157 in C7 and G1S and 159 in G6) of the deduced aa sequences, an alanine residue was found to be conserved among the olive isolates. In citrus and tulip isolates, a threonine residue was present at position 158, whereas a valine was present at this same position in tomato isolates. Phylogenetic analysis indicated that OLV-1 isolates clustered in five groups according to original host. However, G6, originally recovered from olive but repeatedly inoculated and maintained in N. benthamiana plants for 8 years in our laboratory, was separated from other isolates. This may be attributable to adaptation to the experimental host over time. There was no correlation of phylogenetic grouping of isolates based on geographical location or year of collection. Strong negative selection may have contributed to the low diversity among the OLV-1 CP isolates.
