Summary: Background electrolytes can affect the precipitation and dissolution rates of calcite, potentially impacting the kinetic isotope fractionation between calcite and dissolved inorganic carbon (DIC). In this study, inorganic calcite was grown from NaCl-CaCl2 solutions to examine the effects of ionic strength on the oxygen isotope fractionation. The results showed no significant ionic strength effect on the fractionation. However, at NaCl concentrations above 0.35M, the isotopic equilibrium between DIC and water could not be maintained due to the inhibitory effect of NaCl on the enzyme carbonic anhydrase. The efficacy of the enzyme decreased exponentially with increasing NaCl concentration. The findings provide insights into oxygen isotope vital effects in marine organisms.

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: The ZjNOL gene in the warm-season turfgrass Zoysia japonica was found to be highly expressed in senescent leaves. ZjNOL accelerates leaf senescence by promoting the accumulation of abscisic acid and carbohydrates, as well as causing excessive accumulation of reactive oxygen species and oxidative stress. Additionally, ZjNOL inhibits photosynthetic efficiency by damaging the oxygen-evolving complex. These findings highlight the important role of ZjNOL in chlorophyll degradation and senescence, making it a valuable candidate gene for genome editing to enhance the green period and photosynthesis efficiency of Z. japonica germplasm.

Summary: This study systematically investigated the interactions between ultrasmall graphene quantum dots (GQDs) and biomacromolecules using carbonic anhydrase (CA) as a model protein. The results showed that GQDs could quench the intrinsic fluorescence of CA in a static binding mode driven by van der Waal interactions and hydrogen bonding. Additionally, the binding of GQDs induced slight conformational changes of CA and resulted in the reduction of its biological functions.

Summary: LCIA is a chloroplast envelope protein associated with the CO2-concentrating mechanism in Chlamydomonas reinhardtii. In this study, LCIA was found to actively transport bicarbonate in both bacteria and plants, providing direct evidence of its role as an HCO3- transporter. The study also introduces a new plant bioassay for testing HCO3- transport activity, which will be valuable for future research on improving crop photosynthetic efficiency using algal CO2-concentrating mechanisms.

Summary: Karst habitats have negative effects on the growth and biodiversity of plants. This study compared the joint effects of carbon and nitrogen metabolism in karst-adaptable Orychophragmus violaceus and non-karst-adaptable Brassica napus under simulated karst habitats. The results showed that factors such as bicarbonate and nitrate had a significant impact on the carbon and nitrogen metabolism and growth of Orychophragmus violaceus, while their effects on Brassica napus were insignificant. The carbon and nitrogen metabolism in Orychophragmus violaceus played a vital role in its adaptation to karst habitats.

Summary: The proportions of assimilated nitrate and ammonium in Brassica napus plantlets grown at different ammonium/nitrate ratios were quantified using stable nitrogen isotope tracer technique. The utilization proportions of sucrose and CO2 were quantified by a two end-member isotope mixing model. Increasing the nitrate concentration promoted the ammonium assimilation and enhanced the ammonium utilization coefficient. The amount of nitrogen derived from nitrate assimilation increased with increasing nitrate concentration, while the nitrate utilization coefficient showed no significant change.

Summary: Enhanced silicate dissolution by green microalgae, such as Chlamydomonas reinhardtii and Chlorella pyrenoedosa, has been found to effectively remove CO2 from the atmosphere. The presence of these microalgae significantly enhances the dissolution rate of peridotite, with a higher effect observed in the early stage of interaction. It is estimated that one milligram of chlorophyll-a biomass from these microalgae can remove 0.44 and 0.24 mg CO2 per day, respectively, through accelerated dissolution. However, the issue of decelerated dissolution rate over time needs to be addressed to improve CO2 sequestration efficiency.

Summary: Carbon neutrality is a widely concerned and highly valued issue for many countries. The biosphere provides a good example for human beings to achieve carbon neutrality by balancing oxygen and CO2. Photosystem II acts as a carbonic anhydrase in the process of photosynthetic oxygen evolution, initiating the carbon and water neutrality. The study also found that bicarbonate can promote photosynthetic oxygen evolution, and that photosynthetic oxygen evolution can come from both bicarbonate and water. This research sheds light on the understanding of photosynthesis and its role in achieving carbon neutrality in nature.

Summary: Insufficient inorganic nitrogen in karst soils often leads to poor growth in artificial young forests. However, little is known about the assimilatory demand of nitrate for the whole plant and the partitioning of nitrate assimilation in roots and leaves of woody plants in karst habitats. This study used the isotope mass balance approach to quantify the δ^15N values of N assimilates in different plant organs and in whole plants of Broussonetia papyrifera seedlings grown under different nitrate concentrations. The δ^15N values of N assimilates in the whole seedlings showed an increasing trend with higher nitrate concentration. Increasing the nitrate supply decreased the leaf-root difference in δ^15N values of N assimilates. Quantifying the δ^15N values of N assimilates in B. papyrifera seedlings grown under different nitrate concentrations contributes to estimating their assimilatory demand for nitrate, while the leaf-root difference in δ^15N values can be used to estimate the partitioning of nitrate assimilation between roots and leaves.

Summary: This study investigated the effects of varying concentrations of sodium bicarbonate on the growth, electrophysiological properties, intracellular water metabolism, nutrient transport, photosynthesis, and chlorophyll fluorescence of Coix lacryma-jobi L. It was found that a concentration of 2.0 mmol L-1 sodium bicarbonate effectively improved the biomass formation and various physiological parameters of Coix lacryma-jobi L., while concentrations of 7.0 and 12.0 mmol L-1 had inhibitory effects on photosynthesis and plant growth. The study highlights the importance of appropriate bicarbonate levels in enhancing plant physiological functions and suggests that electrophysiological measurement is superior to photosynthesis measurement for monitoring these responses.
