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: 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: In response to flooding, low-chill stone fruit rootstocks showed reduced net CO2 assimilation and nutrient contents, while antioxidant activities and osmolyte concentrations increased. Rootstocks MP-29 and R5064-5 exhibited higher tolerance and antioxidant activities, making them better suited for subtropical areas prone to flooding. Antioxidant activities and osmolyte concentrations may play a key role in mitigating oxidative damage caused by flooding stress in Prunus rootstocks.

Summary: The seed yield in lentils has increased by 1.1% per year in Australia over the past 27 years. Changes in plant traits, such as increased height and leaf size with reduced number of branches, have occurred through breeding. Increased light interception and physiological changes, such as higher CO2 assimilation rate and lower canopy temperature at high temperature, are associated with improved yield in recently released varieties.

Summary: This study aimed to evaluate the effects of different doses of Si on the photosynthetic traits of cotton plants cultivated under rainfed and irrigated conditions. The results showed that there was no significant interaction between Si doses and cultivation conditions, and Si did not influence the photosynthetic parameters of cotton plants. However, irrigation was found to be a beneficial strategy for increasing the CO2 assimilation rate, stomatal conductance, and transpiration of cotton plants.

Summary: The performance of avocado orchards growing in clayey soil irrigated with treated wastewater for a long period of time has declined. Mitigation measures such as freshwater or blended irrigation have been found to improve orchard performance, with freshwater being the most effective option.

Summary: This study investigated the drought resistance of two maize cultivars released in different years under different environmental factors (CO2 concentration and irrigation). The results showed that higher CO2 concentrations improved water use efficiency (WUE) and drought conditions significantly enhanced WUE. Jingke 968 exhibited higher WUE under higher CO2 concentration and light intensity.

Summary: Drought stress significantly reduced the maximum CO2 assimilation rate in soybean but not in rice. Under drought conditions, both crops showed an increase in A after a step increase in light, followed by a gradual decrease in A, resulting in the significant reduction of steady-state A in both rice and soybean. Additionally, drought stress delayed photosynthetic induction in both crops, despite having a relatively small impact on maximum A.

Summary: This study investigates the effects of water deficit and flooding stress on rice's intrinsic water-use efficiency (iWUE) and the relationship between iWUE variations and stress-induced physiological changes. The results show that water deficit and flooding stress decrease rice's photosynthetic and water transport capacities, leading to an increase in iWUE. However, improved iWUE cannot prevent yield reduction. Interestingly, the decrease in photosynthetic capacity is significantly correlated with the decline in water transport capacity. This study has important implications for understanding crop physiological responses to environmental stresses.

Summary: Grazing has a positive impact on the performance and resilience of the endemic Moroccan species Argania spinosa, as it increases photosynthetic rate, photochemical efficiency, and drought tolerance, although the compensation mechanism is limited during summer drought.

Summary: Abiotic stress, especially drought, poses a significant challenge to sustainable agriculture. The use of zinc oxide nanoparticles (ZnO NPs) has been shown to enhance plant growth and improve crop production during drought stress. This study investigated the role of ZnO NPs in managing drought stress in Coriandrum sativum plants. The results demonstrated that foliar application of 100 ppm ZnO NPs improved the photosynthetic activity, chlorophyll content, and abscisic acid levels in drought-stressed plants.

Summary: Flg22 affects the guard cells of tomato plants by causing stomatal closure and a decrease in CO2 assimilation. It also leads to a decrease in sugar content and an increase in hexokinase activity. These are all defense responses of tomato plants.

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: Photosynthesis is a crucial process supporting life on Earth, but unfavorable environmental conditions and toxic metals may limit its efficiency in plants, with genotypes showing varying responses. This study evaluated the photosynthetic parameters of different chili pepper varieties exposed to cadmium (Cd), thallium (Tl), and vanadium (V), and found that these metals could either inhibit or stimulate photosynthetic parameters depending on the genotype and dosage.

Summary: Shoot branching is highly influenced by environmental factors. The rosebush, which requires strict light for branching, is an excellent model for studying light's impact on branching. This study reviews the current understanding of how light affects the regulatory network of hormones, nutrients, and ROS to control branching. It also explores the role of miRNAs in branching regulation and discusses how light may modulate miRNA-dependent regulation of branching.

Summary: Rosebush plants are an excellent model for studying light control of bud outgrowth. High levels of H2O2 in quiescent axillary buds strongly repress the outgrowth process, but clearing H2O2 through the AsA-GSH pathway in light promotes bud outgrowth. Cytokinin application can evoke bud outgrowth in both light and darkness, with the initial target of light being CKs in the photocontrol process.
