Molecular circadian rhythms are robust in marine annelids lacking rhythmic behavior

The circadian clock controls behavior and metabolism in various organisms. However, the exact timing and strength of rhythmic phenotypes can vary significantly between individuals of the same species. This is highly relevant for rhythmically complex marine environments where organismal rhythmic diversity likely permits the occupation of different microenvironments. When investigating circadian locomotor behavior of Platynereis dumerilii, a model system for marine molecular chronobiology, we found strain-specific, high variability between individual worms. The individual patterns were maintained for several weeks. A diel head transcriptome comparison of behaviorally rhythmic versus arrhythmic wildtype worms showed that 24h cycling of core circadian clock transcripts is identical between both behavioral phenotypes. While behaviorally arrhythmic worms showed a similar total number of cycling transcripts compared to their behaviorally rhythmic counterparts, the annotation categories of thei..., Here we described the data provided in addition to the publication 'Molecular circadian rhythms are robust in marine annelids lacking rhythmic behavior' (doi: 10.1371/journal.pbio.3002572).

Reference transcriptome description:The reference transcriptome used for read mapping was created from samples of regenerated Platynereis dumerilii tail pieces (newly grown blastema + adjacent old segment) collected at different stages of regeneration (0, 1, 2, 3 and 5) staged according to Planques et al. 2019 [1]. Per regeneration stage, 3 replicates were collected (n=15 samples total). After library preparation with poly-A enrichment, samples were sequenced on an Illumina NovaSeq System (S1 flow cell, 100bp paired-end reads). The sequencing produced ~141 million reads (after standard quality control) that were assembled into a de novo transcriptome of 364,574 transcripts incl. isoforms (GC content: 39.65%, m..., , # Data from: Molecular circadian rhythms are robust in marine annelids lacking rhythmic behavior
