A birch ELONGATED HYPOCOTYL 5 gene enhances UV-B and drought tolerance

Forestry Research
UV-B radiation and drought majorly restrict plant growth, particularly in summer. ELONGATED HYPOCOTYL 5 (HY5), a bZIP transcription factor (TF), has a beneficial impact on photomorphogenesis.

Mechanisms and therapeutic opportunities of the ribotoxic stress response in cancer

Molecular Oncology, EarlyView.
Cancer cells' high translational demand creates opportunities to therapeutically target ribosome function. Ribosome stalling and collisions activate ZAKα and the ribotoxic stress response (RSR), which can trigger rapid, p53‐independent apoptosis in cancer.

Assessing precipitation, evapotranspiration, and NDVI as controls of U.S. Great Plains plant production

Ecosphere, 2019
Productivity throughout the North American Great Plains grasslands is generally considered to be water limited, with the strength of this limitation increasing as precipitation decreases.

Sensitivity of yellow passion fruit to ultraviolet-B radiation

Pesquisa Agropecuária Brasileira, 2012
The objective of this work was to evaluate the effects of UV-B radiation on the vegetative growth and on the gas exchange characteristics of passion fruit plants (Passiflora edulis) grown in greenhouse. The average unweighted UV-B radiation near the apex

Direct and indirect effects of UV-B exposure on litter decomposition: a meta-analysis. [PDF]

PLoS ONE, 2013
Ultraviolet-B (UV-B) exposure in the course of litter decomposition may have a direct effect on decomposition rates via changing states of photodegradation or decomposer constitution in litter while UV-B exposure during growth periods may alter chemical ...

Revisiting the role of phenylpropanoids in plant defense against UV-B stress

Plant Stress, 2023
Ultraviolet-B (UV-B) radiation from the past few decades has been widely studied due to the substantial depletion of the stratospheric ozone (O3) layer, causing morphological, physiological, cytological, and biochemical alterations in plants. As a potent

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

FEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Cell compartmentation of UV-absorbing compounds in two aquatic mosses under enhanced UV-B [PDF]

, 2012
The effects of enhanced UV-B radiation on UV-absorbing compounds (UVAC), the maximum quantum yield of photosystem II (Fv/Fm), DNA integrity, and the sclerophylly index, were analyzed in the mosses Bryum pseudotriquetrum and Fontinalis antipyretica.

Topical Ajwa date (Phoenix dactylifera L.) extract cream modulates fibroblast proliferation in UV-B-Exposed Wistar rats: Effects on TNF-alpha and SOD levels

Jurnal Teknologi Laboratorium
Humans always want to look attractive and youthful, in order to increase self-confidence, so they make efforts to avoid the appearance of signs of aging by slowing down and preventing the aging process.

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

FEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.
