Detection of Large Numbers of Novel Sequences in the Metatranscriptomes of Complex Marine Microbial Communities

This study provides further evidence that metatranscriptomic studies of natural microbial communities are not only feasible, but when paired with metagenomic data sets, offer an unprecedented opportunity to explore both structure and function of microbial communities--if we can overcome the challenges of elucidating the functions of so many never-seen-before gene families.
