TLDR
An overview of the current knowledge on both circadian and circalunar clocks of the worms, as well as their interactions on molecular and behavioral levels is provided.Abstract:
The marine annelid Platynereis dumerilii coordinates its life in accordance to the daily sun cycle but also with the monthly changes of the moon. These rhythms are driven by internal molecular oscillators, both entrained by light. Here we provide an overview of our current knowledge on both circadian and circalunar clocks of the worms, as well as their interactions on molecular and behavioral levels.read more

Journal ArticleDOI
An Overview of Monthly Rhythms and Clocks.
TL;DR: In this article, the authors focus on adaptations of animals to the lunar cycle, specifically, on the occurrence of biological rhythms with monthly (circalunar) or semi-monthly (circasemilunar), period lengths.
Journal ArticleDOI
Rhythms of behavior: are the times changin'?
TL;DR: An overview of various rhythmic behaviors, connected environmental factors and endogenous mechanisms of terrestrial species, and how anthropogenic effects can affect behavioral rhythmicity and how this might affect ecosystems in the future is provided.

Nest initiation and flooding in response to season and semi-lunar spring tides in a ground-nesting shorebird
Silvia Plaschke,Martin Bulla,Martin Bulla,Martin Bulla,Medardo Cruz-López,Salvador Gómez del Ángel,Clemens Küpper,Clemens Küpper +7 more
TL;DR: Snowy Plovers appear generally well adapted to the risk of nest flooding by spring tides, in line with other studies showing that intertidal organisms have evolved adaptive responses to predictable rhythmic tidal changes but these adaptations do not prevent occasional catastrophic losses caused by stochastic events.

Differential Impacts of the Head on Platynereis dumerilii Peripheral Circadian Rhythms
Enrique Arboleda,Martin Zurl,Martin Zurl,Monika Waldherr,Monika Waldherr,Kristin Tessmar-Raible,Kristin Tessmar-Raible +6 more
TL;DR: These data show that peripheral circadian rhythms and clocks should also be considered in “non-conventional” molecular model systems, i.e., outside Drosophila melanogaster, Danio rerio, and Mus musculus, and build a basic foundation for future investigations of interactions of clocks with different period lengths in marine organisms.

Metazoan evolution: Some animais are more equal than others
Florian Raible,Detlev Arendt +1 more
TL;DR: Comparison of newly available sequence data facilitates reconstruction of the gene inventory of the Urbilateria, the last common ancestor of flies, nematodes and humans, and finds that human genes seem to be closer to the bilaterian roots than previously assumed.

Improving CRISPR-Cas nuclease specificity using truncated guide RNAs
TL;DR: It is reported that truncated gRNAs, with shorter regions of target complementarity <20 nucleotides in length, can decrease undesired mutagenesis at some off-target sites by 5,000-fold or more without sacrificing on-target genome editing efficiencies.
Journal ArticleDOI
double-time Is a Novel Drosophila Clock Gene that Regulates PERIOD Protein Accumulation
TL;DR: It is proposed that the normal function of DOUBLETIME protein is to reduce the stability and thus the level of accumulation of monomeric PER proteins, which would promote a delay between per/tim transcription and PER/TIM complex function, which is essential for molecular rhythmicity.

Post-translational modifications regulate the ticking of the circadian clock
Monica Gallego,David M. Virshup +1 more
TL;DR: Mutations in kinases and phosphatases in hamsters, flies, fungi and humans highlight how their timepieces are regulated and provide clues as to how the authors might be able to manipulate them.

Peroxiredoxins are conserved markers of circadian rhythms

Baliga,Martha Merrow,Andrew J. Millar,Carl Hirschie Johnson,Charalambos P. Kyriacou,John S. O’Neill,Akhilesh B. Reddy +18 more
TL;DR: It is shown that oxidation–reduction cycles of peroxiredoxin proteins constitute a universal marker for circadian rhythms in all domains of life, by characterizing their oscillations in a variety of model organisms and exploring the interconnectivity between these metabolic cycles and transcription–translation feedback loops of the clockwork in each system.

The Drosophila Clock Gene double-time Encodes a Protein Closely Related to Human Casein Kinase Iε
Brian Kloss,Jeffrey L. Price,Lino Saez,Justin Blau,Adrian Rothenfluh,Cedric S. Wesley,Michael W. Young +6 more
TL;DR: DBT is capable of binding to PER in vitro and in Drosophila cells, suggesting that a physical association of PER and DBT regulates PER phosphorylation and accumulation in vivo.
