Abstract
Onion yellow dwarf virus (OYDV) is one of the most important viral diseases of garlic crops worldwide. This study surveyed the occurrence of OYDV in 26 garlic ecotypes collected from different regions in Iran during 2008–2009. Using an electron microscope, we detected filamentous particles with about 700–800 nm in length and 12 nm in width in five samples. These features are typical of the genus Potyvirus. The coat protein (CP) gene from 26 samples was PCR amplified, cloned, sequenced, and compared with the sequences available in GenBank. Phylogenetic analysis using 235 deduced amino acids of the CP gene showed that virus isolates fell into two groups, group A and group B. Members of group A were divided into two subgroups: A-I and A-II. The subgroup A-I appears to be a new subgroup comprising 17 Iranian isolates. The identity levels among the amino acid of 26 Iranian isolates ranged between 90 and 100%. The results indicated that the genetic diversity found in Iran is due to local OYDV populations rather than introduction from other geographical regions. This study is the first report about the molecular structure and geographically diverse range of OYDV populations in this country.
