Diel Protein Regulation of Marine Picoplanktonic Communities Assessed by Metaproteomics.

ABSTRACT: The diel cycle is of enormous biological importance in that it imposes temporal structure on ecosystem productivity. In the world's oceans, microorganisms form complex communities that carry out about half of photosynthesis and the bulk of life-sustaining nutrient cycling. How the functioning of microbial communities is impacted by day and night periods in surface seawater remains to be elucidated. In this study, we compared the day and night metaproteomes of the free-living and the particle-attached bacterial fractions from picoplanktonic communities sampled from the northwest Mediterranean Sea surface. Our results showed similar taxonomic distribution of free-living and particle-attached bacterial populations, with Alphaproteobacteria, Gammaproteobacteria and Cyanobacter
