Whole genome characterisation of Australian and New Zealand OsHV-1 ‘μVar’ like variants over time

Abstract

Highlights • Fifteen OsHV-1 µVar-like genomes assembled from Australia and New Zealand.• Whole-genome phylogeny places Australia/New Zealand viruses in a distinct clade.• Shared 6.5 kb deletion and recurrent indels concentrate in repeat-rich regions.• Marker gene trees failed to detect clade divergence, supporting genome-wide typing and surveillance.
