Why we should care about pathogenic viruses in our plants

Thanks, Lee.  You raise a question that I've not checked out:  Why not 
vaccines for plants? Maybe no antibodies?  The only thing I'm aware of in 
this area is acetylsalicylic acid as a trigger for what approximates an 
immune respnse in plants,and I followed that literature for a while and 
occasionally drench a n endangered plant of mine with an aspirin solution to 
help it get well. Haven't kept any records though except to note that it 
doesn't help arisaemas infected wtih Uromyces.  It appears at first to 
help-- but they're don't survive to the next year..

I enjoyed Jacob's essay and it caused me to think of a couple of points:

1. Not only are some microorganisms not bad, the "flora" in human
gastrointestinal system for example, which we've known about for years,
is considered to be essential. So much so, that scientists decided to
