Complete Genome Sequence of a New Circular DNA Virus from Grapevine

See on Scoop.itVirology and Bioinformatics from Virology.ca

“A novel circular DNA virus sequence is reported from grapevine. The corresponding genomic organization, coding potential, and conserved origin of replication are similar to those of members of the family Geminiviridae, but the genome of 3,206 nucleotides is 4% larger than the largest reported geminiviral genome and shares only 50% overall sequence identity.”

Interesting stuff!  These novel ssDNA viruses are popping up everywhere – probably because they ARE everywhere, well adapted to natural hosts, only rarely transmitted to crop species, and we only stumble upon them by deep sequencing.  Or blind luck.
