Sažetak
Diatoms are important primary producers that play a crucial role in global marine ecosystems. The aim of the ASSEMBLE project “Biodiversity of marine diatoms: morphological and molecular characterization (BIOMARDI)“ was to investigate the planktonic species from the Adriatic Sea belonging to the genera Pseudo-nitzschia, Chaetoceros and Bacteriastrum. The general morphology and ultrastructure of these diatoms were studied with light and electron microscopy and compared with the information from databases, field samples and culture collection available in the host institution (SZN). The results revealed the existence of 9 Pseudo-nitzschia species of which 6 are considered to be potential producers of toxin domoic acid. In addition to the morphological analyses the Bacteriastrum taxa were also analysed in terms of molecular phylogeny. In one of the investigated species, B. jadranum, we discovered and described a novel strategy of colony formation apparently unique among marine planktonic diatoms.
