Variation of expression levels of clock genes.

Abstract

<p>Relative transcription levels (RQ, mean ± SEM, n = 9 oysters) of <i>Cg6-4photolyase</i>, <i>CgCry1</i>, <i>CgpCry</i>, <i>CgCry2</i>, <i>CgClock</i>, <i>CgBmal</i>, <i>CgPeriod</i>, <i>CgTim</i>, <i>CgRev-Erb</i> and <i>CgROR</i> RNA in gill tissues of oysters exposed for 26 h to L:D 10:14 (□) and for 26 h to constant darkness (■). Gray areas referred to scotophase during L:D cycles. Significant differences at <i>p</i> < 0.05 between light regimes are indicated and asterisks denote significant time-specific differences between light regime treatments.</p
