Abstract	:	Citrus are an important subsistence and commercial crop across the South and Central Pacific. Unfortunately, the spread of plant material has contributed to the spread of citrus pathogens, such as Citrus tristeza virus (CTV). In this study, we examined the incidence and diversity of CTV strains present in both New Zealand, and island nations of the South and Central Pacific, and found that all presently described strains are present, and exist and complex mixtures of strains. Phylogenetic analysis suggests little difference in strain diversity between locations, suggesting extensive movement of infected planting material occurred in the past.
