Mrs Ciasulli did you know:

"Plants, like humans can run a fever if they are sick" ?

We have known this for a long time (like the 1950's) but the mechanism is not understood. Infected plants were compared to uninfected plants. The infected leaves had an increased rate of gas exchange which led to an increased temp. Is this evolution? 
Higher temperatures prevent RNA transcription of a virus. Since plants do not produce antibodies, maybe this is their only alternative?
