Summary: The study investigated the effects of light intensities and harvesting times on the photosynthesis of green and purple basil plants. The results showed that purple basil had the highest photosynthetic and protective pigment levels when harvested at noon, while the highest levels of soluble and storage carbohydrates were detected in purple basil grown under full sunlight and harvested during the early morning. Light treatments also affected the maximum quantum yield of photosystem II (FV/FM) and the non-photochemical quenching (NPQ) in both basil varieties.

Summary: In this study, a genome-wide association study (GWAS) was conducted using a diversity panel of 518 Brassica napus inbred lines grown in four different soil and light environments. 281 single-nucleotide polymorphisms (SNPs) significantly associated with photosynthetic pigment content-related traits were identified. Additionally, 46 candidate genes involved in chlorophyll and carotenoid metabolism were identified. The identified SNPs and candidate genes could contribute to the study of natural variation in photosynthetic pigment accumulation and provide valuable resources for future high photosynthetic efficiency breeding.

Summary: Full-spectrum light-emitting diodes (LEDs) with specific amber and blue light wavelengths and bandwidths were studied for their effects on tomato growth and production efficiency. Narrow amber light combined with narrow blue light led to the highest fresh mass yield, followed by white LED and a high-pressure sodium lamp. Chlorophyll content increased with the addition of blue light. The findings suggest that precise selection of amber and blue wavelengths can greatly impact tomato growth and development, making narrow-wavelength combination a more energy-efficient option.

Summary: This study found that different day-length regimes significantly influenced the plant response to fungal infection. Under long-day and continuous light conditions, approximately 30% of Brassica juncea plants showed a 'green island' phenotype, with a green ring surrounding a necrotic area on the leaf. This phenomenon also affected chlorophyll and carotenoid contents, as well as photosynthesis efficiency.

Summary: Chlorophyll fluorescence can be used as a proxy for photosynthesis in boreal forests. This study measured the spectral chlorophyll fluorescence in leaves of three dominant evergreen species in the boreal ecosystem and analyzed the correlations with other traits to understand the spatial and temporal variation in chlorophyll fluorescence. The findings suggest that the diversity of species and light environments within an ecosystem generate baseline variation in leaf spectral chlorophyll fluorescence and contrasting seasonal photosynthetic acclimation patterns.

Summary: This study investigated the effects of anticipated future elevated CO2 on growth, physiology, and nutrient uptake in two widely cultivated mulberry varieties in southwest China. The results showed that elevated CO2 significantly increased plant growth but decreased chlorophyll concentrations and photosynthetic rates, while also leading to lower leaf N and P concentrations. Nutrient dilution and changes in plant demand were identified as key factors driving the reduction of leaf N and P under elevated CO2 conditions.

Summary: SC and NT are two different modern orchard management systems in Taiwan for sustainable citrus orchard development. SC showed higher physiological parameters like Rd, Qy, LCP, Amax, and Fv/Fm compared to NT, especially in fall and winter. Pn, Gs, ETR, NPQ, and Fv/Fm values were higher in spring and summer compared to fall and winter, with positive correlations between Pn and Gs under both NT and SC in all seasons, and significant negative relationships between ETR and NPQ under NT in fall and winter.

Summary: This study aimed to improve the production of valuable substances in Rhodopseudomonas faecalis PA2 by using different light regimes. Single-phase cultivation maximized biomass, carotenoid, and bacteriochlorophyll contents, while two-phase cultivation significantly increased protein, lipid, and carbohydrate productivities compared to single-phase cultivation. This novel light strategy was effective in manipulating the production of valuable substances in this strain.

Summary: The ambitious project in the North Sea aims to build an offshore wind-powered electrolyser for green hydrogen production. However, uncertainties and component capacity dependencies have affected the economic success of PtH2 plants and the competitiveness of hydrogen production technology. Through a techno-economic analysis, this paper determines the lowest selling price by optimizing the components and investigates the impact of variables such as wind and hydrogen demand on system layouts. The results show that the hydrogen price can reach 2.2 euro/kg for certain combinations of maximum demand and electrolyser capacity.

Summary: The industrial cold stores can store thermal energy as passive thermal energy. They can contribute with flexible consumption by cooling further in periods of low-cost electricity. To fulfill the potential, data measurement is necessary to control the cold stores and ensure food safety. A case study showed that cooling further in periods of low-cost electricity could result in 30% savings, which could reach up to 40% with proper price forecasting. The full capacity of cold stores in Denmark can potentially use 2% of the average wind electricity production for thermal energy storage.
