Genomic and proteomic evidences unravel the UV-resistome of the poly-extremophile Acinetobacter sp. Ver3 [PDF]

, 2015
Ultraviolet radiation can damage biomolecules, with detrimental or even lethal effects for life. Even though lower wavelengths are filtered by the ozone layer, a significant amount of harmful UV-B and UV-A radiation reach Earth?s surface, particularly in

The ZmCOP1s–ZmCOL3 Module Enhances Late Flowering, Grain Yield and Grain Quality in Maize

Plant Biotechnology Journal, EarlyView.
ABSTRACT Flowering time is a key determinant of yield and regional adaptation in crops and is largely controlled by light signalling. In this study, we identified two maize orthologs of Arabidopsis CONSTITUTIVE PHOTOMORPHOGENIC 1 (COP1), designated ZmCOP1a and ZmCOP1b, which activate light signalling and reduce plant height. Loss‐of‐function mutants of

Impact of additional green light and deficit in cryptochrome 1 on photosynthetic activity and pro-/antioxidant balance in Arabidopsis thaliana

Photosynthetica, 2023
The light spectral composition acting through a set of photoreceptors, such as cryptochromes and phytochromes, plays an important role in maintaining sustainable photosynthesis.

Striking circadian neuron diversity and cycling of Drosophila alternative splicing. [PDF]

, 2018
Although alternative pre-mRNA splicing (AS) significantly diversifies the neuronal proteome, the extent of AS is still unknown due in part to the large number of diverse cell types in the brain.

Engineered Production of Hydroxycinnamoyl Tyramine Conjugates Limits the Growth of the Pathogen Pseudomonas syringae in Arabidopsis

Plant, Cell &Environment, EarlyView.
ABSTRACT Hydroxycinnamoyl tyramine conjugates are phenolamides produced by plants in response to pathogen attack and biotic stresses. Their proposed mechanisms of action include cytotoxicity towards pathogens, cell wall reinforcement to restrict pathogen proliferation, and signaling activity to trigger general stress responses.

Structure and Function of Animal Cryptochromes [PDF]

Cold Spring Harbor Symposia on Quantitative Biology, 2007
Cryptochrome (CRY) is a photolyase-like flavoprotein with no DNA-repair activity but with known or presumed blue-light receptor function. Animal CRYs have DNA-binding and autokinase activities, and their flavin cofactor is reduced by photoinduced electron transfer.

A photo-responsive F-box protein FOF2 regulates floral initiation by promoting FLC expression in Arabidopsis. [PDF]

, 2017
Floral initiation is regulated by various genetic pathways in response to light, temperature, hormones and developmental status; however, the molecular mechanisms underlying the interactions between different genetic pathways are not fully understood ...

Prolonged exposure to artificial light and carcinogenesis: A systematic review of oncostatic mechanisms associated with melatonin pathways

Photochemistry and Photobiology, EarlyView.
Exposure to artificial light at night (ALAN), particularly at blue wavelengths, disrupts circadian rhythms by suppressing melatonin, thereby increasing cancer susceptibility. This systematic review consolidates evidence linking prolonged ALAN exposure to an elevated risk of breast and prostate tumors.

Solving the mystery of human sleep schedules one mutation at a time. [PDF]

, 2013
Sleep behavior remains one of the most enigmatic areas of life. The unanswered questions range from "why do we sleep?" to "how we can improve sleep in today's society?" Identification of mutations responsible for altered circadian regulation of human ...

Impacts of exercise, renin–angiotensin system modulation or both on skeletal muscle circadian gene expression

Experimental Physiology, EarlyView.
Abstract Ageing negatively affects quality of life and healthspan, and interventions are needed to slow this progressive decline. Previously, we have demonstrated the potential functional benefits of combining a genetically modified probiotic (GMP) targeting the non‐canonical arm of the renin–angiotensin system (RAS) with exercise training.
