This paper identifies PafA, a phosphate-insensitive phosphatase in Bacteroidetes, which plays a major role in phosphate remineralization in the environment and is important for phosphorus cycling in nature.

The paper shows that type IV pili in picocyanobacteria help them avoid sinking and evade predation by increasing drag and maintaining suspension in the water column.

This study identifies a novel Ca2+-dependent signaling pathway in diatoms that links phosphorus sensing to nitrogen metabolism, enhancing nutrient uptake and bloom formation.
