The duckweed collection at the Matthias
Schleiden Institute at Friedrich Schiller University of Jena, Germany, headed by one of the
co-authors, KJA, has more than 500 clones of
duckweeds. Initially, a large portion of the collection came from the Landolt Duckweed Collection from ETH, Zurich. Many clones were
also investigated by molecular markers (Bog
et al. 2010, 2013, 2015, 2018; Borisjuk et al.
2015). This clonal collection of the 36 species of
duckweeds, over the years, is constantly being
used for several comparative physiological
studies, investigations on biodiversity of duckweed species, laboratory and field-testing of
several practical applications of duckweeds by
researchers and entrepreneurs and, also for the
development of molecular markers for determining species identity.
