Summary: The study found that elevated CO2 significantly increased the net photosynthetic rate of rice, especially during the jointing stage. This stimulation was acclimated with the advance of the growing season and was not affected by stomatal limitations or Rubisco activity.

Summary: Photosynthetic efficiency varies among different rose genotypes, with stomatal conductance playing a crucial role in determining the efficiency under fluctuating light conditions. This study compared the photosynthetic performance of two modern rose cultivars and one old Chinese rose plant, revealing the importance of mesophyll conductance in dynamic photosynthesis and its potential for improving photosynthetic efficiency in rose cultivars.

Summary: This study analyzed the morpho-physiological responses of 30 cowpea genotypes to waterlogging, revealing that under waterlogging conditions, cowpea plant height, leaf area, and weight decreased while water use efficiency and adventitious roots increased. Chlorophyll fluorescence parameters were also affected. The study identified waterlogging-tolerant and sensitive cowpea genotypes, which could be useful for genetic engineering and breeding programs aimed at improving cowpea waterlogging tolerance.

Summary: This study investigated the diurnal variations in leaf electrophysiology, water potential, gas exchange, and chlorophyll fluorescence parameters of three plant species in karst areas. The results showed that different plant species have different strategies for regulating photosynthetic performance.

Summary: Ecological research has mainly focused on identifying how different environmental factors restrict photosynthesis, but there is less attention on accurately modeling the transition between limitations as drivers change. Whether these changes are modeled as a single switch or involve an intermediate period of co-limitation can significantly impact estimated levels of photosynthesis.

Summary: The efficiency-safety tradeoff in plant water transport and stomatal regulation has been studied. Recent research revealed that plants with higher maximum stomatal conductance (g(max)) are more sensitive to stomatal closure during soil drying, resulting in less negative leaf water potential at 50% g(max) (psi(gs50)). This tradeoff can be explained by the effects of soil-plant hydraulics on water movement and plant hydraulic properties, such as conductance and embolism resistance.

Summary: The study evaluated the effect of SS on the growth of Alibertia edulis seedlings, finding that concentrations below 50% contributed to growth improvement, while concentrations above 50% had a negative impact on seedling quality, including decreased biomass and abnormal leaf morphology.

Summary: This study investigated the response of mangrove plants to salinity and submergence in different tidal conditions. The photosynthetic capacity and chlorophyll fluorescence parameters were measured, revealing that immersed Kandelia obovata plants were tolerant to submergence, while Rhizophora stylosa plants were salt-tolerant. Treatment with 30 ppt salinity resulted in lower photosynthetic rates and increased non-photochemical quenching and heat quenching.

Summary: Research shows that sun-induced chlorophyll fluorescence (SIF) can be used to estimate plant transpiration (T), providing theoretical support and potential basis for ecosystem T derivation. The water-use efficiency (WUE) method and conductance method for estimating T via SIF demonstrated good performance when compared with measured evapotranspiration.

Summary: Leaf stomata play a crucial role in the exchange of water vapor and carbon dioxide. Optimization models for stomatal regulation have been successful but differ in their mathematical details, indicating the need for further investigation. This study proposed a new stomatal optimization model based on water-carbon balance, and compared it with existing models. The results showed differences in stomatal sensitivity to soil moisture, and the new model captured the response patterns well.

Summary: Abyssal polymetallic nodule fields are unique deep-sea habitats. The presence of hard substratum, such as nodules and rocks, promotes the occurrence of diverse abyssal assemblages. The contribution of rocks to habitat heterogeneity has been largely overlooked, but our study shows that they play an important role in enhancing biodiversity and habitat complexity within nodule fields.

Summary: Experimental systems simulating future elevated CO2 conditions often have fluctuating CO2, which can reduce photosynthesis by decreasing stomatal conductance and the photochemical efficiency of photosystem II. However, the impact of CO2 fluctuations varies among different species, with some showing no change in photosynthesis and stomatal conductance.

Summary: Blue and red light are important light signals for regulating stomatal development and leaf structure. This study investigated the response of stomatal and leaf traits in soybeans to blue and red light at two light intensities. The results showed that stomatal size remained unchanged under blue light, while stomatal density, specific leaf weight, and maximum stomatal conductance were unaffected by the decrease in light intensity under red light. These findings suggest that stomatal density and specific leaf weight are regulated by blue light, while stomatal size is highly sensitive to red light. Furthermore, specific leaf weight and stomatal density had the highest contribution rates to maximum stomatal conductance. Overall, these results indicate that long-term exposure to blue light enhances maximum stomatal conductance through the synergistic promotion of specific leaf weight and stomatal density.
