| Abstract: | We analyzed the evolutionary histories of two lily strains of Cucumber mosaic virus (CMV) isolated in Japan and Korea (HL- and Ly2-CMVs). They share common biological characteristics in that their host ranges
are very restricted perhaps from a unique adaptation to lily plants. Although HL and Ly2 were isolated independently from
different lily species in separate countries, their RNA3 sequences had a very high sequence similarity (97%). The evolutionary
relationships between the two isolates were characterized by comparing their phylogenetic trees for the 3a and CP genes. The
two lily CMVs always formed a distinct cluster within subgroup IB in 3a, but within IA in CP. Together, the phylogenetic tree
topology and the sequence identity between the two lily CMVs suggest that they evolved from a common progenitor.
