Experiments with the green alga Scenedesmus quadricauda confirmed previous findings that according to the irradiance level two different phenomena occur, which were further characterised by specific changes in several photosynthetic parameters. The reaction occurring under low irradiance (shade reaction) is characterised by heavy metal substitution of Mg2+ in chlorophyll molecules bound predominantly in the LHC II. Under high irradiance (sun reaction) the LHC II chlorophylls are inaccessible to substitution and the damage occurs in the PS II reaction centre instead. Algae with antenna proteins other than the LHC II did not show the two types of heavy metal attack at different irradiances. In red algae (Antithamnion plumula), low Cu2+ concentrations induced the sun reaction even at very low irradiance. In brown algae (Ectocarpus siliculosus) the shade reaction occurred even in saturating irradiance. These results also indicate that despite some similarity in their features, the primary step of the sun reaction and photoinhibition is different.</dcterms:abstract> <dcterms:rights rdf:resource="https://rightsstatements.org/page/InC/1.0/"/> <dcterms:isPartOf rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/28"/> <dcterms:title>Heavy metal-induced inhibition of photosynthesis : targets of in vivo heavy metal chlorophyll formation</dcterms:title> <dc:creator>Küpper, Frithjof C.</dc:creator> <dspace:isPartOfCollection rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/28"/> <dcterms:bibliographicCitation>Publ. in: Journal of Phycology ; 38 (2002), 3. - S. 429-441</dcterms:bibliographicCitation> <dc:contributor>Spiller, Martin</dc:contributor> <dc:contributor>Setlik, Ivan</dc:contributor> <dc:date rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-12-07T13:36:42Z</dc:date> <dc:contributor>Küpper, Hendrik</dc:contributor> <dc:creator>Prasil, Ondrej</dc:creator> <dc:creator>Setlik, Ivan</dc:creator> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-12-07T13:36:42Z</dcterms:available> </rdf:Description> </rdf:RDF>
