- Abstract
Two Citrus tristeza virus (CTV) isolates from New Zealand that display distinct phenotypes were isolated, examined and sequenced in full. The first isolate, NZ-M16, is largely asymptomatic and non-transmissible by the aphid vector Toxoptera citricida, while the second, NZ-B18, is highly transmissible and induces very severe symptoms on C. sinensis and C. aurantii. Phylogenetic analysis of the genome sequences showed that both isolates were approximately 90–93% similar to the VT and T318 isolates but possessed only 89% identity to one another. Based on sequence identity, both isolates are VT subtypes, with NZ-M16 being T3-like, while NZ-B18 is a member of a novel subtype with B165 from India.
