Tobacco rattle virus genome alterations in the Hosta hybrid 'Green Fountain' and other plants: reassortments, recombinations and deletions.
Tobacco rattle virus from a Hosta hybrid contained one RNA1 (Ho-1) and two RNA2 species (Ho-2a, Ho-2b). Whereas Ho-1 resembles TRV Al RNA1 from Alstroemerias, Ho-2a and Ho-2b resemble TRV TpO1 RNA2 from a potato field. Ho-2a has a complete RNA2-specific sequence, whereas that of Ho2-b carries a large deletion. The short RNA1-related 3' end of Ho-2a is distinct from that of Ho-1, whereas the longer one of Ho-2b is identical to that of Ho-1. TRV RNA2 molecules may apparently become associated with different TRV RNA1 molecules, from which they can acquire 3'ends of various lengths while often losing large portions of their RNA2-specific sequences.
