Previous studies on the diatom Phaeodactylum tricornutum indicate that the formation of a high light acclimated phenotype is mediated by the absorption of BL and that aureochromes might play an important role in this process. P. tricornutum possesses four genes encoding aureochromes. In this study we confirm the nuclear localisation of the PtAUREO1a, 1b and 2 proteins. Furthermore we studied the physiology of light quality acclimation in genetically transformed P. tricornutum cell lines with reduced expression of the aureochrome 1a gene. The results demonstrate that the AUREO1a protein has a distinct function in light acclimation. However, rather unexpectedly AUREO1a seems to repress high light acclimation which resulted in a state of "hyper" high light acclimation in aureo1a silenced strains. This was indicated by characteristic changes of several photosynthetic parameters, including increased maximum photosynthesis rates, decreased chlorophyll a contents per cell and increased values of non-photochemical quenching in AUREO1a silenced strains compared to wild type cultures. Strikingly, AUREO1a silenced strains exhibited phenotypic differences compared to wild type cells during cultivation under BL as well as under red light (RL) conditions. Therefore, AUREO1a might influence the RL signalling process, suggesting an interaction of AUREO1a with RL perception pathways.</dcterms:abstract> <dc:creator>Wilhelm, Christian</dc:creator> <dc:rights>deposit-license</dc:rights> <dc:contributor>Jungandreas, Anne</dc:contributor> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2014-01-13T13:24:14Z</dcterms:available> <dc:creator>Schellenberger Costa, Benjamin</dc:creator> <dc:creator>Gruber, Ansgar</dc:creator> <dc:creator>Jungandreas, Anne</dc:creator> <dcterms:issued>2013</dcterms:issued> <dc:contributor>Wilhelm, Christian</dc:contributor> <dcterms:bibliographicCitation>PLoS ONE ; 8 (2013), 9. - e74451</dcterms:bibliographicCitation> <dcterms:title>Aureochrome 1a is involved in the photoacclimation of the diatom Phaeodactylum tricornutum</dcterms:title> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2014-01-13T13:24:14Z</dc:date> <dc:creator>Sachse, Matthias</dc:creator> <dc:creator>Jakob, Torsten</dc:creator> <dc:contributor>Rio Bartulos, Carolina</dc:contributor> </rdf:Description> </rdf:RDF>
