The role and implications of mammalian cellular circadian entrainment

FEBS Letters, EarlyView.
At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

Cattle manure and humic substances stimulate morphophysiological and nutritional processes in pepper plants

Revista Brasileira de Engenharia Agrícola e Ambiental
Species of the genus Capsicum, especially peppers, are economically important and widely consumed worldwide. The application of animal waste as organic fertilizer is a simple and cost-effective technique for applying nutrients to the soil.

Bread Wheat Landraces Adaptability to Low-Input Agriculture

Plants, 2023
Bread wheat landraces were an important source of biodiversity used in agriculture before the widespread adoption of high-yielding commercial cultivars adapted to high inputs. Could future agriculture exploit these landraces in different cropping systems

Molecular bases of circadian magnesium rhythms across eukaryotes

FEBS Letters, EarlyView.
Circadian rhythms in intracellular [Mg2+] exist across eukaryotic kingdoms. Central roles for Mg2+ in metabolism suggest that Mg2+ rhythms could regulate daily cellular energy and metabolism. In this Perspective paper, we propose that ancestral prokaryotic transport proteins could be responsible for mediating Mg2+ rhythms and posit a feedback model ...

Alternative systems aim to reduce inputs, maintain profits

California Agriculture, 1994
The economic component of the Sustainable Agriculture Farming Systems (SAFS) project at UC Davis compared the financial performance of low-input and organic farming systems to conventional systems. All of the systems have been profitable over the first 4

The coupling of Phanerozoic continental weathering and marine phosphorus cycle

Scientific Reports, 2020
Organic matter production and decomposition primarily modulate the atmospheric O2 and CO2 levels. The long term marine primary productivity is controlled by the terrestrial input of phosphorus (P), while the marine P cycle would also affect organic ...

The high organic carbon accumulation in estuarine wetlands necessarily does not represent a high CO2 sequestration capacity

Environment International, 2023
Estuarine wetlands with high organic carbon (OC) accumulation rates due to their high plant biomass and interception of tide-derived OC are generally considered as large CO2 sinks.
