title: Russian isolates of potato spindle tuber viroid.
abstract: Forty PSTVd isolates collected from five regions of Russia (North-western, Central, Volga region, Northern Caucasus and the Far East) were sequenced during 2006-2008. All isolates lacked the adenine residue present at position 123 of the type strain; i.e., PSTVd-intermediate (GenBank V01465). Nineteen Russian isolates also contained an adenosine --> cytosine substitution at position 120. Twenty two additional unique changes were also observed in one or more of the isolates sequenced.
