Diat.barcode was initially named RSyst::diatom Significant diversity exists within the main freshwater algal classes: Diatoms (10 000 to 100 000 taxa), Chrysophyceae (over 1000 taxa), Chlorophyceae (over 4000 taxa), Zygophyceae (over 3000 taxa), Dinophyceae (over 500 taxa), Euglenophyceae (over 1000 taxa), Cryptophyceae (over 120 taxa). Their huge diversity and their ubiquity make them excellent ecological indicators for rivers, lakes and marine (eg water framework directive) waters. Metabarcoding enables the automation of identifications which have until now been done under the microscope. Diat.barcode database is a library of barcodes which is curated and which guarantees good taxonomical homogeneity and good quality of sequences. Data have different sources: The culture collection of Thonon, INRAE, TCC The barcoding project of diatoms in UK Public data (NCBI) Several European labs participate in this curation: INRAE – UMR Carrtel, FR–74200 Thonon–les–Bains, France Botanischer Garten und Botanisches Museum Berlin–Dahlem, Freie Universität Berlin, Germany Swedish University of Agricultural Sciences, Department of Aquatic Sciences and Assessment, Uppsala, Sweden Bowburn Consultancy, Durham, UK Royal Botanic Garden Edinburgh, Edinburgh, Scotland, UK Marine and Continental Waters, Institute for Food and Agricultural Research and Technology (IRTA), Catalonia, Spain Institute of Plant Physiology, Russian Academy of Sciences, Russia Laboratory for Evolutionary Ecology, center for Marine Research, Ruder Boskovic Institute, Rovinj, Croatia Luxembourg Institute of Science and Technology (LIST) Environmental Research and Innovation (ERIN) Department, Belvaux, Luxembourg Gilles Gassiole, France (MicPhyc) R-Syst is a french network a research teams which objective is to develop a dictionary of genetic and phenotypic variability, thus enabling a better characterisation of these organisms.
