Chemoproteomic Identification of Blue-Light-Damaged Proteins

, 2022
Visible light, particularly in the blue region of the spectrum, can cause cell dysfunction through the generation of singlet oxygen, contributing to cellular aging and age-related pathologies.

Blue-Light-Switchable Bacterial Cell–Cell Adhesions Enable the Control of Multicellular Bacterial Communities

, 2020
Although the fundamental importance and biotechnological potential of multibacterial communities, also called biofilms, are well-known, our ability to control them is limited. We present a new way of dynamically controlling bacteria–bacteria adhesions by

The Interaction Between Nitrogen Supply and Light Quality Modulates Plant Growth and Resource Allocation

Frontiers in Plant Science, 2022
Nitrogen availability and light quality affect plant resource allocation, but their interaction is poorly understood. Herein, we analyzed the growth and allocation of dry matter and nitrogen using lettuce (Lactuca sativa L.) as a plant model in a ...

Red light represses the photophysiology of the scleractinian coral Stylophora pistillata. [PDF]

PLoS ONE, 2014
Light spectrum plays a key role in the biology of symbiotic corals, with blue light resulting in higher coral growth, zooxanthellae density, chlorophyll a content and photosynthesis rates as compared to red light.

Green Light Improves Photosystem Stoichiometry in Cucumber Seedlings (Cucumis sativus) Compared to Monochromatic Red Light

Plants, 2021
It has been shown that monochromatic red and blue light influence photosynthesis and morphology in cucumber. It is less clear how green light impacts photosynthetic performance or morphology, either alone or in concert with other wavelengths.

Adding Blue to Red Supplemental Light Increases Biomass and Yield of Greenhouse-Grown Tomatoes, but Only to an Optimum

Frontiers in Plant Science, 2019
Greenhouse crop production in northern countries often relies heavily on supplemental lighting for year-round yield and product quality. Among the different spectra used in supplemental lighting, red is often considered the most efficient, but plants do ...

Inactivation of Campylobacter jejuni by exposure to high-intensity 405-nm visible light [PDF]

, 2010
Although considerable research has been carried out on a range of environmental factors that impact on the survival of Campylobacter jejuni, there is limited information on the effects of violet/blue light on this pathogen. This investigation was carried
