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

open access: yesResponsive 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

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

open access: yesFrontiers 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 ...

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

open access: yesSustainable 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.

Light stress-induced chloroplast movement and midday depression of photosynthesis in sorghum leaves

open access: yesPlant Production Science, 2020
Plants are exposed to high light intensity, high leaf temperatures and high air-to-leaf water vapor pressure deficit (ALVPD) during the day. These environmental stresses cause stomatal closure and photoinhibitory damage, leading to midday depression of ...

Genome‐scale insights into metabolic streamlining and photosynthetic energy balance in the extremophile green alga Picocystis salinarum (Picocystophyceae, Chlorophyta)

open access: yesJournal of Phycology, EarlyView.
Abstract Picocystis salinarum is an early‐diverging chlorophyte and the sole described member of the Picocystophyceae, frequently dominating hypersaline and alkaline lakes despite extreme physicochemical constraints. To elucidate the genomic foundations of its ecological success, we generated a fully annotated, chromosome‐scale nuclear genome assembly ...

Potential impact of photoinhibition on microphytobenthic primary production on a large intertidal mudflat

open access: yes, 2021
Microphytobenthos (MPB) are a key primary producer of intertidal mudflats. MPB face strong variability in incident irradiance during low tides. Despite photoprotection and photoacclimation, such variations can translate into photoinhibition of MPB cells.

Extending the limits of algal growth and stress resilience – the desert alga Chlorella ohadii as an emerging model

open access: yesNew Phytologist, EarlyView.
Multiple facets of Chlorella ohadii biological properties and potential as a research model and biotechnology platform. Summary Since its isolation from the sand dunes of the Negev Desert over a decade ago, the unicellular green alga Chlorella ohadii has turned into a reference organism for studying photosynthesis, metabolism, and abiotic stress ...

Phosphatidylcholine acyl turnover facilitates thylakoid lipid remodeling and promotes plant survival under heat stress

open access: yesNew Phytologist, EarlyView.
Coordinated galactolipid–TAG conversion during heat stress–induced thylakoid lipid remodeling. Summary Heat stress destabilizes chloroplast membranes, requiring rapid lipid remodeling to maintain photosynthetic function. Although thylakoid lipid remodeling and triacylglycerol (TAG) accumulation are established heat responses, the role of ...

Hidden Strategies Beneath a Single Nucleotide: Contrasting Physiology in Lichen Photobiont Strains

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Lichen photobionts exhibit significant physiological variability with important ecological implications. While this variability is relatively well studied at the interspecific level, it has rarely been examined at the intraspecific level. Here, we investigated the physiological responses to temperature and irradiance of two Trebouxia lynniae ...

Photoinhibition of photosystem II in tobacco plants overexpressing glutathione reductase and poplars overexpressing superoxide dismutase

open access: yes, 1999
We studied photoinhibition in two cultivars of tobacco (Nicotiana tabacum L,) expressing the bacterial gor gene In the cytosol and in four lines of poplar (Populus tremula x P, alba) expressing the FeSOD gene of Arabidopsis thaliana in the chloroplast ...
