Using assemblies of polyA-selected eukaryotic metatranscriptomes, Ryan Groussman led an exploration of how 48 marine eukaryotic genera regulate their gene expression over the diel cycle in the North Pacific Subtropical Gyre. Groussman finds that each taxonomic group has a relatively distinct transcriptional fingerprint. Yet, the diel cycle is a critical driver of the coordinated activities found across these various taxa. This study comes from the Simons Foundation SCOPE-Aloha Program. Check it out here.
