Oceanic phytoplankton species are generally composed of many strains, with intra-species diversity consisting of genetic and phenotypic variability. Despite its importance in ecological and biotechnological contexts, this intra-species diversity and variation among strains has been little studied. We investigated the intra-species diversity of the microalga Tisochrysis lutea , a haptophyte of the Isochrysidales order. Inter-strain diversity of T. lutea was studied because of the economic importance of the species as a feed in aquaculture and for antioxidant metabolite production, particularly fucoxanthin and other carotenoids, which have health benefits. We analysed Tara Ocean datasets which revealed that T. lutea was present in the Pacific, Atlantic and Indian Oceans but not in the Arctic or Austral Oceans. We next made phenotypic and genotypic comparisons of 11 strains of T. lutea from worldwide algal collections. All strains were cultivated in the same controlled conditions for one week, and several ...
