From apex to base: Uncovering spatial metabolic adaptation in Antarctic mosses

Bulletin of the Korean Chemical Society, EarlyView.
Antarctic mosses survive extreme cold, desiccation, UV exposure, and oxidative stress. We analyzed three species by separating apical, middle, and basal zones. Each zone showed distinct metabolite patterns and biological roles, revealing spatial metabolic specialization. The results suggest that whole‐plant survival depends on coordinated contributions

Variable photosynthetic sensitivity of maize (Zea mays L.) to sunlight and temperature during drought development process

Plant, Soil and Environment, 2017
The complex interaction process of the abiotic factors (sunlight, air temperature and soil water) in regulating maize (Zea mays L.) photosynthesis has not been fully understood.

The relationship between cellular protein content and selenium accumulation in freshwater microalgae

Integrated Environmental Assessment and Management, EarlyView.
Abstract Variability in the bioconcentration of selenium (Se) by primary producers at the base of the food web results in uncertainty in predictions of bioaccumulation and ecological risk to higher trophic level organisms. Water chemistry, speciation of Se, and periphyton community composition have all been suggested as factors that contribute to ...

Upregulation of the mitochondrial alternative oxidase pathway improves PSII function and photosynthetic electron transport in tomato seedlings under chilling stress

Photosynthetica, 2022
The aim of this study was to explore how the mitochondrial alternative oxidase (AOX) pathway alleviates photoinhibition in chilled tomato (Solanum lycopersicum) seedlings.

Leaf heat tolerance in a native Californian shrub responds in expected and unexpected ways to differences in range, season, and sunlight exposure

PLANTS, PEOPLE, PLANET, EarlyView.
Earth's ecosystems are experiencing wide‐ranging impacts from global climate change, including increased average and extreme temperatures. These temperature shifts can drastically affect plant physiology, threatening the future of even common plant species. Here, we focus on photosynthetic function in a native Southern California shrub species.

When and how does photoinhibition matter for plant fitness?

, 2022
The many biophysical factors that shape how plant species sort across environmental gradients may include photoinhibition, which I define broadly as oxidative damage that plants and other phototrophs risk incurring when they absorb excess light energy ...

Efficient water‐soluble blue/red‐emissive carbon dots matching plant absorption spectra: Synthesis, tunable control, and their applications in promoting plant growth

Responsive Materials, EarlyView.
Guided by the spectral demand of plant photosystems, this review summarizes the synthesis, emission regulation, dual‐emission design, and gram‐scale production of CDs for agricultural applications. Spectrally matched blue‐ and red‐emissive CDs enhance plant light utilization by converting underutilized light into photosynthetically active radiation and

Agrivoltaic Lettuce Production Under Future Climates: A Sustainable Strategy for Optimizing Food and Energy Yields

Sustainable Development, EarlyView.
ABSTRACT Food system resilience is increasingly challenged by climate change and global trade volatility, even in high‐income nations like Canada. Agrivoltaics—co‐locating crops and photovoltaics (PV)–offers a sustainable production strategy to optimize land use and address both food and energy security.

Quality control of Photosystem II: reversible and irreversible protein aggregation decides the fate of Photosystem II under excessive illumination

Frontiers in Plant Science, 2013
In response to excessive light, the thylakoid membranes of higher plant chloroplasts show dynamic changes including the degradation and reassembly of proteins, a change in the distribution of proteins, and large-scale structural changes such as ...

Improved primary production and gross respiration measurements using the H218O technique with membrane inlet mass spectrometry and introduction of a small volume–uniform irradiance incubation chamber

Journal of Phycology, EarlyView.
Abstract An improvement in the H218O technique for phytoplankton gross primary productivity (GPP), net primary productivity (NPP), and gross respiration (GR) is described that reduces cost, labor, and time over the traditional isotope ratio mass spectrometer (IRMS) method.
