Interplay between circadian and other transcription factors—Implications for cycling transcriptome reprogramming

FEBS Letters, EarlyView.
This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

EFFECTS OF COVER BOARD AGE, SEASON, AND HABITAT ON THE OBSERVED ABUNDANCE OF EASTERN RED-BACKED SALAMANDERS (PLETHODON CINEREUS) [PDF]

, 2014
Plethodontid salamanders are potentially good ecological indicator species in woodland habitats due to their abundance and sensitivity to changes in the environment.

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing

FEBS Letters, EarlyView.
Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

Seedling establishment early on an abandoned field

Plant Protection Science, 2001
The effect of sporadic cultivation on seedling establishment on a field abandoned for 1-4 years was investigated in small-plot trials at Prague-Ruzyně in the spring periods 1993-1995. Cultivation included autumn ploughing, spring harrowing and rolling on

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Barium abundance in red giants of NGC 6752. Non-local thermodynamic equilibrium and three-dimensional effects

, 2012
(Abridged) Aims: We study the effects related to departures from non-local thermodynamic equilibrium (NLTE) and homogeneity in the atmospheres of red giant stars in Galactic globular cluster NGC 6752, to assess their influence on the formation of Ba II ...

The oxygen abundance calibrations and N/O abundance ratios of ~40,000 SDSS star-forming galaxies [PDF]

, 2006
Using a large sample of 38,478 star-forming galaxies selected from the Second Data Release of the Sloan Digital Sky Survey database (SDSS-DR2), we derive analytical calibrations for oxygen abundances from several metallicity-sensitive emission-line ...

Krill of the Ross Sea: distribution, abundance and demography of Euphausia superba and Euphausia crystallorophias during the Italian Antarctic Expedition (January-February 2000)

Scientia Marina, 2002
Net samples data from the 15th Italian Antarctic Oceanographic Cruise (Jan-Feb 2000) were analysed to obtain a general picture of the summer distribution pattern, abundance and demography of krill in the western Ross Sea (Antarctica).
