Photosystem II-Carbon Nitride Photoanodes for Scalable Biophotoelectrochemistry. [PDF]

Adv Mater
A spray‐freeze method is developed to fabricate large‐area (up to 33 cm2) macroporous carbon nitride photoanodes integrated with photosystem II enzymes for biophotoelectrochemical systems. The photoanodes reach a Faradaic efficiency of 93.5% for O2 evolution.

Effect of saline irrigation on Tetragonia tetragonioides (Pall.) Kuntze grown on different soil types under greenhouse conditions

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Climate change and population growth are major challenges for sustainable food production, particularly in regions affected by water scarcity and soil salinization. In this context, halophytes represent promising candidates as alternative and sustainable food crops for salt‐affected areas.

The functional role of protein dynamics in photosynthetic reaction centers investigated by elastic and quasielastic neutron scattering

EPJ Web of Conferences, 2015
This short review summarizes our current knowledge about the functional relevance of protein dynamics in photosynthetic reaction centers. In the case of Photosystem II membrane fragments, elastic and quasielastic neutron scattering experiments reveal a ...

Optimization of light spectrum and intensity to enhance growth and metabolite profiles in green and purple radish microgreens cultivated in a vertical farming system

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Microgreens have emerged as a promising crop in vertical farming due to their high nutritional value and short growth cycles. Light spectrum and intensity are critical factors influencing biomass production and metabolic activity in plants, particularly in controlled environments such as vertical farming systems. This study aimed to

Multiple impacts of loss of plastidic phosphatidylglycerol biosynthesis on photosynthesis during seedling growth of Arabidopsis

Frontiers in Plant Science, 2016
Phosphatidylglycerol (PG) is the only major phospholipid in the thylakoid membrane in cyanobacteria and plant chloroplasts. Although PG accounts only for ~10% of total thylakoid lipids, it plays indispensable roles in oxygenic photosynthesis. In contrast

pamfit: A new R package for spatially resolved analysis of Imaging PAM photosynthesis–irradiance light curve parameters

Limnology and Oceanography: Methods, EarlyView.
Abstract Imaging Pulse Amplitude Modulation (PAM) fluorometry allows spatially resolved measurements of Photosystem II (PSII) fluorescence kinetics through time without disturbing study organisms or their environments. In particular, the use of photosynthesis–irradiance curves (P–I curves) provides detailed information on PSII quantum efficiency ...

Strain specific differences in rates of Photosystem II repair in picocyanobacteria correlate to differences in FtsH protein levels and isoform expression patterns.

PLoS ONE, 2018
Picocyanobacteria are the numerically dominant photoautotrophs of the oligotrophic regions of Earth's oceans. These organisms are characterized by their small size and highly reduced genomes.

Selenium induced lower respiratory potential in Glycine max (L.) Merr.

Acta Agriculturae Slovenica, 2010
Effect of selenium (Se) was studied in soybean (Glycine max (L.) Merr.) cv. Olna in Ljubljana, Slovenia. Se was added to plants as foliary spraying. Quantum yield of photosystem II (PSII) and respiratory potential measured as ETS activity of mitochondria

Wheat breeding approaches for designing wheat to thrive in a warmer world

PLANTS, PEOPLE, PLANET, EarlyView.
Wheat is a vital food crop, accounting for approximately 20% of daily calories and protein consumed worldwide. However, modern‐day wheat is under pressure from global change. The improvement rate of wheat yields is not keeping up with the demand of our growing population. Furthermore, abiotic and biotic stressors are becoming more prevalent. This paper

Carotenoids assist in cyanobacterial Photosystem II assembly and function

Frontiers in Plant Science, 2016
Carotenoids (carotenes and xanthophylls) are ubiquitous constituents of living organisms. They are protective agents against oxidative stresses and serve as modulators of membrane microviscosity.
