Gene expression profiling of Antarctic krill in DD condition

This work represents the first characterization of the krill circadian transcriptome under laboratory conditions and provides a first insight into the genetic regulation of physiological changes, which occur around the clock in light-dark (LD) and in constant darkness (DD) condition. Gene expression profiling was performed with the ‘‘Krill 2.0’’ custom platform (Agilent) in specimens collected at regular intervals throughout the 24 hours cycle (external times: 06:00, 09:00, 12:00, 15:00, 18:00, 21:00, 24:00, 03:00 and 06:00) in constant darkness (DD) condition.
