There's more than one question here, just as there are many plant viruses,l and families of viruses. tobamoviruses,. cucumber viruses, potato viruses, and lest you think so, be aware that just because the name sugggests that potatoes are affected by certain viruses, this does not mean that the virus has read the book (memorializing the discovery of the entity) and only attack, say, potatoes. There are iris viruses, peony viruses, etc., and they all keep evolving. I've not heard of anybody deliberately infecting a plant to make it variegated. Where did you hear about it? Very disturbing news, if true. ----- Original Message ----- From: "Josh Young" <joshy46013@yahoo.com> To: <pbs@lists.ibiblio.org> Sent: Tuesday, July 20, 2010 5:19 PM Subject: [pbs] Virus (was x Amarygia leaves) I've heard of people using Aphids to give plants variegation, is this sort of virus spreadable to other plants through other plants? What would be the reason for people would want that? It's obvious that the plant is sick which would make it undesirable, right? _______________________________________________ pbs mailing list pbs@lists.ibiblio.org http://pacificbulbsociety.org/list.php http://pacificbulbsociety.org/pbswiki/
