Description

The chain-forming marine centric diatom Skeletonema marinoi Sarno & Zingone was described in 2005, as one of four new species identified in the Skeletonema costatum complex (Sarno et al., 2005). In the Baltic Sea, S. marinoi is the dominant species from this genus (Sjöqvist et al., 2015) and several studies have focused on its ecology and evolution (e.g. Godhe & Härnström, 2010; Härnström et al., 2011; Sefbom et al., 2018). The genomes of ten bacteria from the S. marinoi microbiome have also been sequenced, to inform on the interactions within the diatom-bacteria holobiont (Johansson et al., 2019a). Several molecular techniques have been developed for this species, including a method for genetic transformation, involving mutagenesis (Johansson et al., 2019b) and Secondary ion mass spectrometry (Stenow et. al 2024) making it a useful tool for studies of evolution, functional genomics and ecology. The sequenced strain R05AC is available from the algal bank at University of Gothenburg (GUMACC).
