Episode 5 – Microbes can switch sides in the plant-pathogen battle!

Episode 5 Listen to episode [http://traffic.libsyn.com/bacteriofiles/BF182.mp3] This is a special, joint episode between The Plant Pathology Podcast and Bacteriofiles. [http://www.bacteriofiles.com] We talk about how the same microbes that associate with plants can sometimes help prevent disease, and sometimes assist the pathogen. It depends on which microbe gets there first!
