Special Online Collection: Plant Volatiles -- From Chemistry to Communication

Jump to features in special collection:

Plant VolatilesThis week on the Science Web sites, a special collection of articles explores the complex and fascinating cloud of volatile compounds with which plant communicate with the outside world. Reviews and Perspectives in Science delve into the evolution, function, and biochemistry of plant volatiles, and the complex volatile signaling implicit in everything from a glass of wine to a ripe tomato. (An audio interview with one of the Review authors is featured on the 10 February Science Podcast.) A set of features and a Teaching Resource on the Signal Transduction Knowledge Environment examine additional aspects of plant signaling on the molecular level. The Science of Aging Knowledge Environment looks into the nature of age-related olfactory loss. And ScienceCareers.org offers a special set of articles on careers in plant science.
