摘要: Diatoms are among the most successful primary producers in ocean and freshwater environments. Deriving from a secondary endosymbiotic event, diatoms have mixed genome containing bacterial, animal plant genes encoding for metabolic pathways that may account their evolutionary success. Studying transcriptomes of two strains diatom Skeletonema marinoi, we report, first time microalgae, an active animal-like prostaglandin pathway is differentially expressed strains. Prostaglandins hormone-like mediators many physiological pathological processes mammals, playing pivotal role inflammatory responses. They also present macroalgae invertebrates, where they act as defense communication mediators. The occurrence prostaglandins unicellular photosynthetic eukaryotes opens up new intriguing perspectives on evolution these molecules marine environment possible cell-to-cell signaling, eventually influencing population dynamics plankton.
