The current dataset includes 516 accessions (clones) from the CNR-IBBA duckweed collection. This collection primarily consists of clones from the historical Landolt Duckweed Collection, which was previously housed in Zurich (https://www.duckweed.ch/?lang=en). The identity of some Lemna species has been validated or revised using molecular methods, specifically Tubulin-based Polymorphism (TBP). The entire plants are maintained in axenic culture following subcloning and sterilization with sodium hypochlorite (NaClO).

The expected outcome of the activity is the implementation of a national network of biological research collections, including all the existing in vivo and ex-situ collections of biological organisms (animals, plants, fungi, algae, archaea, bacteria, viruses, etc.) which have been created and maintained through past and current research projects.\n\nBioMemory is the network of biological collections of the Department of Biology, Agriculture and Food Sciences (DiSBA) of the National Research Council of Italy (CNR) for bio-monitoring, biodiversity conservation, agri-food and environmental sustainability, and human well-being. The project is aimed to create a network of biobanks (i.e., scientific research collections) where data and metadata associated to biological samples of different nature are collected and stored in a systematic and well-organized way.
