A new paper authored by BioBE Center Director Jessica Green and former Center members Ann (Womack) Klein and Brendan Bohannan was recently published in the open-access journal Biogeosciences. The paper examined fungal communities in the atmosphere over the Amazon rainforest canopy using DNA- and RNA- based sequencing to examine the total and metabolically active communities, respectively. To our knowledge, this is the first study to sequence RNA from outdoor air samples. Collecting and isolating RNA from air samples required the development of novel methods which open the door for future studies of metabolically active microorganisms in the built environment.
