Tobacco Virus Jumps 1.6 Billion Years of Evolution to Honeybee

More research on colony collapse disorder:

“When HIV jumped from chimpanzees to humans sometime in the early 1900s, it crossed a gulf spanning several million years of evolution. But tobacco ringspot virus, scientists announced last week, has made a jump that defies credulity. It has crossed a yawning chasm ~1.6 billion years wide. And this is likely bad news for its new host, the honeybee, matchmaker of crops and bringer of honey.  …

As scientists were studying the possible role of pollen in spreading known bee viruses, a team of scientists from the United States and China began screening bees and pollen for viruses of all sorts. To their surprise, as they reported Jan. 21 in the journal mBio, they discovered a common plant virus — tobacco ringspot virus — had seemingly infested honeybees. Was it merely a transient visitor? Or had it made itself at home in a place inconceivably different from its usual digs?”
