Table 5.

Nucleotide diversity in the C region (including the microsatellite region) of OsHV-1 from different geographical regions. The data are based on sequences listed in Table 2 of Supplementary data 3 as well as sequences from the current study. Six sequences were added to be consistent with Mineur et al (2015) (see materials and methods). NW Pacific includes isolates from China, Japan and Korea; NE Pacific includes Mexico and USA; Europe includes France, Ireland, Italy, Portugal and Spain; Australasia includes Australia and New Zealand.
