Synechococcus, one of the most abundant cyanobacteria in marine ecosystems, displays a broad pigment diversity. However, the in situ distribution of pigment types remains largely unknown. In this study, we combined flow cytometry cell sorting, whole-genome amplification, and fosmid library construction to target a genomic region involved in light-harvesting complex (phycobilisome) biosynthesis and regulation. Synechococcus community composition and relative contamination by heterotrophic bacteria were assessed at each step of the pipeline using terminal restriction fragment length polymorphism targeting the petB and 16S rRNA genes, respectively. This approach allowed us to control biases inherent to each method and select reliable WGA products to construct...

Predicting responses of plankton to variations in essential nutrients is hampered by limited in situ measurements, a poor understanding of community composition, and the lack of reference gene catalogs for key taxa. Iron is a key driver of plankton dynamics and, therefore, of global biogeochemical cycles and climate. To assess the impact of iron availability on plankton communities we explored the comprehensive bio‐oceanographic and ‐omics datasets from Tara Oceans in the context of the iron products from two state‐of‐the‐art global scale biogeochemical models. We obtained novel information about adaptation and acclimation towards iron in a range of phytoplankton, including picocyanobacteria and diatoms, and identified whole sub‐communities co‐varying with...
