Summary: Expression of VPZ genes in potato plants accelerates the induction and relaxation of photoprotection under various light conditions but does not improve photosynthetic rate or plant growth. Instead, tuber yield decreases under fluctuating light conditions. The negative effect may be due to reduced radiation use efficiency caused by strong NPQ induction under high light conditions.

Summary: The study reveals that elevated atmospheric CO2 can mitigate PSI photoinhibition under fluctuating light by facilitating rapid oxidation of PSI and activating more electron acceptors.

Summary: The study showed that pre-illumination under high light conditions accelerates the activation rate of cyclic electron flow (CEF) and reduces the over-reduction of Photosystem I (PSI) under fluctuating light, by facilitating the electron sink downstream of PSI.

Summary: The absence of ndh genes in many species of eukaryotic algae and certain vascular plants provides insights into the natural selection of photosynthesis-related genes in evolution. Plants without ndh genes are on the verge of extinction due to variable evolutionary environments, and most extant species may have recently lost these genes. Additional DNA sequencing and investigations into molecular mechanisms in Gymnosperms lacking ndh genes will help develop a unified model of the evolutionary and functional consequences of their absence.

Summary: This study demonstrates that overexpressing K+ exchange antiporter 3 (KEA3) and introducing Flv proteins can alleviate photodamage of photosystem I and enhance the rate of CO2 fixation under fluctuating light conditions.

Summary: Photorespiration plays an important role in maintaining photosynthetic carbon assimilation and energy balancing under dynamic light conditions. It is closely linked to the C-3 cycle and can help balance fluxes. Regulation of photorespiration is crucial for maintaining appropriate metabolic fluxes related to nitrogen and one-carbon metabolism under dynamic conditions.

Summary: This study investigated the photosynthetic dynamics of the CAM orchid Vanilla planifolia under fluctuating light. The results showed that the light use efficiency was higher in the morning compared to the afternoon. During photosynthetic induction, electron flow through photosystem I reached its maximum value rapidly. A rapid re-oxidation of P700 was observed upon transition from dark to actinic light, indicating the effective utilization of the water-water cycle. In the afternoon, cyclic electron flow was stimulated to optimize photosynthesis.

Summary: In this study, the global proteome of Synechocystis sp. PCC 6803 under fluctuating light conditions was compared with constant light conditions. It was found that cell metabolism was clearly reprogrammed, and there were correlations between mRNA and protein levels to some extent. The data suggest that higher nitrogen assimilation is maintained for long-term acclimation to fluctuating light upon CO2 step-down in Synechocystis sp. PCC 6803.

Summary: This study revealed that low-light phases significantly affect the extent of PSI photoinhibition in fluctuating light conditions, with a higher light intensity inducing a higher proton gradient across thylakoid membranes. The activation of cyclic electron flow (CEF) is finely regulated to optimize the balance between photoprotection and light use efficiency in fluctuating light environments. Additionally, CEF activation in high-light phases is highly dependent on the PSI reduction state.

Summary: Plants adjust their photosynthetic processes to adapt to fluctuating light in the environment. The interconnection of short-term and long-term photosynthetic responses presents a challenge in studying plant acclimation to light fluctuations. Mathematical modeling can help differentiate short-term regulatory responses from long-term acclimation responses, integrating physiological processes across different timescales.

Summary: Photosynthesis is mainly studied under steady-state conditions, but this assumption is inadequate for assessing biochemical responses to rapid variations in natural environments. This study presents a leaf-level System Dynamics photosynthesis model validated on two soybean varieties, and provides relevant conclusions on their different dynamic responses.

Summary: This study reveals that the decrease in leaf N content delays the induction speeds of net CO2 assimilation, stomatal conductance, and mesophyll conductance upon transition from low to high light in tomato seedlings. The photosynthetic induction kinetics are mainly affected by the induction response of mesophyll conductance rather than stomatal conductance.

Summary: Mosses can grow under fluctuating light conditions due to the roles of FLVs and CEF in regulating photosynthesis, especially when exposed to temperature stress. The coordination between FLV activity and CEF under fluctuating light and temperature stress is crucial for the photosynthetic acclimation of different moss species. The mosses with different light requirements show distinct FLV activity and CEF levels, indicating a species-specific response to fluctuating light and temperature stress.

Summary: The experiment showed that under fluctuating light conditions, C-4 bioenergy grass species assimilated more carbon than C-3 species, with both types assimilating approximately 16% less carbon than expected based on steady state measurements. There was little diversity in the response to fluctuating light among C-3 species, while differences among the four NADP-ME species in C-4 species were evident. The diversity observed among C-4 species in response to fluctuating light suggests that targeting photosynthetic efficiency could increase C-4 bioenergy grass productivity.

Summary: This study revises attempts to find and quantify the low entropy of organisms, highlighting the absolute entropy of non-living biomass as the reference point for entropy decreases in living beings. It points out that compartmentation of metabolites and departure from metabolic equilibrium contribute to distinctive reductions in entropy, while DNA and proteins have low informational entropy that is relevant for life and evolution. Additionally, it emphasizes the critical role of photosynthetic conversion of energy in maintaining low entropy in living systems.
