New paper on sugar transport and plant defense

New article published in New Phytologist.  JA responses reconfigure the long-distance transport of carbon but not nitrogen in poplar.  Heidi Appel, Tom Arnold, and Jack Schultz

Phenolic substances – including those the deter herbivores and serve as pigments – accumulate in plant tissues because plants can actively boost carbon, but not nitrogen import after wounding.  Phenolics are constructed mostly from carbon atoms and one way to predict their occurrence is to track carbon, in the form of carbohydrates, throughout trees.
