Summary: The research examines the effects of sub-optimal illumination on three plant species by studying chlorophyll fluorescence. The findings show that low light treatment increases pigment content and maintains fluorescence ratios, suggesting conservation of photosystems stoichiometry. Different plant species respond differently to low light, with L. sativa adapting, A. hybridus not significantly stressed, and S. dendroideum decreasing antenna size but increasing quantum yield of primary photochemistry.

Summary: Research evaluated the photosynthetic efficiency of wheat during different stages of Fusarium head blight (FHB) infection, revealing that FHB infection leads to adjustments in photosynthetic efficiency. Variability in photosynthetic adjustments was observed in flag leaves and ears, showing some variety-specific responses, with location playing a more significant role in modulating wheat's response to FHB infection.

Summary: This study found that low P availability negatively affects the growth and photosynthesis of cotton, leading to a decrease in leaf area, dry weight, and gas exchange parameters. Furthermore, low P availability also reduces the activity of antioxidant enzymes and increases the content of malondialdehyde in cotton. These findings provide a theoretical basis for understanding the growth and tolerance of cotton under low-P conditions.

Summary: This study demonstrated the spatiotemporal heterogeneity of chlorophyll content and fluorescence response within rice leaves and canopies. The research revealed that nitrogen supply affects the occurrence time of the reverse vertical pattern and highlights the potential use of end acceptors at photosystem I electron acceptor side per cross section as a sensitive predictor for leaf chlorophyll content heterogeneity.

Summary: This study investigated the influence of TiO2 foliar spray on the yield and photophysiological responses of cherry tomato under low ambient light intensity. Results showed that TiO2 treatment increased electron transport and CO2 fixation in plants under low light conditions, while reducing the fruit size and delaying ripening time. Additionally, TiO2 treatment significantly increased fruit hardness and yield in cherry tomatoes.

Summary: CAM plants have the ability to fix carbon at night and release malic acid during the day, saving water. However, there is limited research on the effects of chilling temperatures on CAM plants. This study emphasizes the importance of understanding the physiological responses to chilling in order to promote sustainability in the horticultural sector.

Summary: This study investigated the functional role of anthocyanins in the photosynthetic apparatus of leaves from Syringa oblata, Syringa oblata var. affinis Lingelsh, and Syringa chinensis under different light conditions. The results showed that anthocyanins could reduce light absorption in Syringa leaves, and the photosynthetic efficiency of Syringa oblata was higher than that of the other two varieties under low light conditions.

Summary: Low temperatures have a significant impact on the geographic distribution of warm-season crops such as cucumber. This study investigates the effects of light intensity on photosynthesis and biochemical traits under low temperature stress. The results show that high photon flux densities exacerbate the negative effects of low temperature on cucumber seedlings.

Summary: This study investigated the effects of drought stress on physiological parameters and photosystem II (PSII) stability in Hedysarum coronarium and Hedysarum carnosum. The results showed that drought stress significantly decreased relative water content, chlorophyll content, and gas exchange. However, H. coronarium plants exhibited better protection in these physiological parameters compared to H. carnosum.

Summary: The study found that increasing concentrations of methyl viologen can lead to decreased growth, pigment content, and metabolic activity of Chlorella vulgaris. Inhibition of electron transport between quinone A and quinone B of photosystem II by MV directly impacts photosynthetic electron transport.

Summary: Leaf coloration changes can trigger different photosynthetic responses among different poplar cultivars. The study found that the red leaf cultivar 'ZHP' had a significantly lower photosynthetic efficiency compared to the green leaf cultivar 'L2025', mainly due to stomatal regulation and different photosynthetic efficiencies. Additionally, the higher anthocyanin content in 'ZHP' was considered to be closely related to the decreased photosynthetic efficiency.
