Often diapause induction and resurrection is light-dependent and therefore dependent on the photoperiod length and on the number of consecutive short-days. In many organisms, including the microcrustacean Daphnia magna, one functional entity with the capacity to measure seasonal changes in day-length is the circadian clock. There is a long-standing discussion that the circadian clock also controls photoperiod-induced diapause. We tested this hypothesis in D. magna, an organism which goes into a state of suspended animation with the shortening of the photoperiod. We measured gene expression of clock genes in diapause-destined embryos of D. magna in the initiation, resting and resurrection phases and checked it against gene expression levels of continuously developing embryos. We demonstrate that some genes of the clock are differentially expressed during diapause induction but not during its maintenance. Furthermore, the photoreceptor gene cry2 and the clock-associated gene brp are highly expressed during induction and early diapause, probably in order to produce excess mRNA to prepare for immediate resurrection. After resurrection, both types of embryos show a similar pattern of gene expression during development. Our study contributes significantly to the understanding of the molecular basis of diapause induction, maintenance and termination.</dcterms:abstract> <dc:creator>Chen, Luxi</dc:creator> <dcterms:available rdf:datatype="">2021-01-14T10:31:57Z</dcterms:available> <dcterms:issued>2020</dcterms:issued> <dcterms:hasPart rdf:resource=""/> <dc:creator>Weiss, Linda C.</dc:creator> <dc:contributor>Weiss, Linda C.</dc:contributor> <bibo:uri rdf:resource=""/> <dspace:isPartOfCollection rdf:resource=""/> <void:sparqlEndpoint rdf:resource="http://localhost/fuseki/dspace/sparql"/> <dc:date rdf:datatype="">2021-01-14T10:31:57Z</dc:date> <dcterms:isPartOf rdf:resource=""/> <dc:creator>Schwarzenberger, Anke</dc:creator> <dc:contributor>Schwarzenberger, Anke</dc:contributor> <dspace:hasBitstream rdf:resource=""/> <dc:contributor>Chen, Luxi</dc:contributor> </rdf:Description> </rdf:RDF>
