Abstract

Molecular characterization and phylogenetic analysis of Ukrainian isolates of Cucumber mosaic virus based on the partial sequences of three genes

Highlights

Cucumber mosaic virus (CMV) is a type species of the genus Cucumovirus and known to infect approximately 1300 species of more than 500 monoand dicotyledonous plant genera among over 100 families, with new hosts reported every year [1]
We described two CMV isolates, Ukr-sq13 (GenBank Accession Number KJ921837) and Ukr-tom2 (GenBank Accession Number KJ921838), belonging to the subgroup IB [13]
We suggest that IB isolates of CMV prevail in Ukraine

Summary

Introduction

Cucumber mosaic virus (CMV) is a type species of the genus Cucumovirus (family Bromoviridae) and known to infect approximately 1300 species of more than 500 monoand dicotyledonous plant genera among over 100 families, with new hosts reported every year [1]. Wide dissemination of CMV suggests its success in rapid adapting to new hosts and new environments [2]. The genome of CMV is a single-stranded positive sense RNA. There are three RNA segments containing five open reading frames (ORF), which are packed in separate icosahedral particles and code for the proteins 1a and.
