Live @ AAAS - Ian Baldwin on 'Talking Trees' (Transcript)

On Monday, 21 February, at 1 p.m. EST Ian Baldwin, a molecular ecologist at the Max Planck Institute for Chemical Ecology in Jena, Germany, will discuss his studies of how plants use chemical signals to fend off hungry insects or attract helpful pollinators. He proposed the controversial "talking trees" hypothesis 25 years ago, and today agricultural researchers are keen to apply his findings toward improving pest resistance in crops.

Submit your questions to him live at noon or post them beforehand in the comments section below.
