Development of full-length cDNA clones of broad bean wilt virus 1 (BBWV-1).
Transcripts of BBWV-1 full-length cDNA clones are highly infectious in different plant hosts.
The biological and molecular characteristics of the viral transcripts were identical to the wild-type BBWV-1 isolate.
The biological activity of viral transcripts was not affected by the addition of extra non-viral nucleotides at the 5′-terminus.
The wide host range of this virus enables to studyhost-virus interactions and use it as viral vector for many plant species.
