Summary: Metabolite profiling and (13)CO(2)labelling studies of Flaveria species reveal the progressive re-wiring of various metabolic processes in the evolution from C(3)to C(4)photosynthesis. This includes the relocation of enzymes, establishment of shuttles, and changes in the concentration of organic acids. The findings support current models and provide further insights into the evolutionary path of C(4)photosynthesis in the genus Flaveria.

Summary: Plants rely on Rubisco for CO2 fixation, but the toxic byproduct 2-phosphoglycolate from Rubisco causes reduced photosynthetic yield in C3 plants, leading to energy-consuming photorespiration. By introducing the BHAC pathway to convert photorespiration metabolites into oxaloacetate, plants can bypass photorespiration in a highly efficient and resource-conserving manner to potentially enhance growth and yield.

Summary: To increase rice yields, it is crucial to identify germplasm with improved efficiency of primary metabolism. This can be achieved by screening genetically diverse populations under altered environmental conditions, such as low CO2 concentrations. In this study, a pipeline was developed to screen mutant populations of rice seedlings under low CO2 conditions, and putative candidates with altered chlorophyll depletion were identified.

Summary: The study showed that a yellow-green leaf mutant ygl53 in rice had increased net assimilation rate, higher photorespiration rate, and lower nitrogen uptake efficiency, but maintained normal development and yield. The mutant demonstrated higher activities of GOGAT and GS to maintain carbon and nitrogen metabolism homeostasis, with energy and substances derived from carbon metabolism supplementing nitrogen metabolism through photorespiration.

Summary: This study presents a carbon-13 washout model for leaf metabolism and identifies three processes that contribute to the labeling of Calvin-Benson cycle (CBC) metabolites. The model integrates CBC, cytosolic sugar pools, the glucose-6-phosphate shunt, and vacuolar sugars into a single system, providing a more complete understanding of carbon movement in photosynthetic metabolism.

Summary: Saussurea involucrata is a cold-resistant plant species that grows in extreme arctic conditions. The key enzyme Fructose-1, 6-bisphosphate aldolase (FBA) plays a crucial role in the photosynthesis process. A cold-responsive gene, SiFBA5, has been identified and shown to positively regulate plant response to cold stress, offering potential for improving crop yield under cold stress conditions.

Summary: Photorespiration is a crucial carbon recovery process in plants, and catalase in peroxisomes plays a protective role by preventing nonenzymatic decarboxylations between hydrogen peroxide and photorespiratory intermediates. Mutants lacking peroxisomal catalase show increased CO2 release from photorespiration, supporting the hypothesis of excess nonenzymatic decarboxylations, particularly the decarboxylation of hydroxypyruvate.

Summary: The study aimed to investigate the growth patterns and photosynthetic responses of rice and tomato plants inoculated with halotolerant PGPB under salt stress conditions. Inoculated plants showed increased growth rate, stimulated root growth, and higher transpiration rates, stomatal conductance, and intracellular CO2 accumulation. Moreover, the restoration of cellular ATP levels in leaves of inoculated plants along with decreased ROS accumulation suggests the protective role of PGPB in alleviating salinity stress responses.

Summary: The increasing human population and environmental deterioration create a need for higher food production per unit area. One approach to enhance crop yields is to harness the lost allelic variation in domestication. This study investigates why wild rice species have decreased grain production despite enhanced photosynthesis rates. Results show that wild rice species exhibit higher photosynthesis, CO2 recovery, production of photosynthates, and efficient N-use compared to domesticated rice, providing directions for future breeding improvements.

Summary: Photosynthesis is the foundation of almost all life on Earth, providing energy and secondary substances that are useful in treating a variety of illnesses. Through the use of photosystems and accessory pigments, photosynthesis converts solar energy into ATP and NADPH+H+. These products are then utilized in the Calvin cycle to fix CO2 and produce fructose.

Summary: This study investigated the role of thylakoid protein phosphorylation in regulating energy-dependent quenching of chlorophyll fluorescence in rice plants. The results showed that phosphorylated proteins were enhanced in the PsbS-KO mutant after illumination, indicating a light-induced process. It was suggested that this enhancement might be due to increased reactive-oxygen-species production in this mutant.

Summary: Nutritional immunity is a host strategy to combat invading pathogens by controlling micronutrient bioavailability to hinder microbial growth. While the role of manganese is well understood in bacterial pathogens, limited data is available for fungi. Fungi have evolved complex regulatory systems for manganese acquisition, distribution, and utilization. Disruption of manganese homeostasis in pathogenic fungi may impact virulence and phenotypes. Further research is needed to determine the importance of manganese in host-pathogen interactions in fungal infections.

Summary: Antifungal resistance is increasing, with Candida auris being highly resistant to antifungal drugs. This study found that treatment with caspofungin led to increased production of extracellular vesicles (EVs) in C. auris and altered the content of RNA and proteins enclosed in the EVs. The ability of C. auris to change the composition of EVs may contribute to its ability to evade antifungal treatment.

Summary: In this study, the authors functionally characterized DGATs in castor beans and found that RcDGAT3 is localized in vesicles outside the ER in leaf epidermal cells and provides higher tolerance over FFA. RcDAcTA is associated with the ER membranes but fails to rescue long-chain TAG biosynthesis. These findings suggest alternative functions and roles of RcDGAT3 in lipid metabolism.

Summary: This study investigated the impact of water availability and nitrogen fertilization on plant growth, nutrient dynamics, and soybean crop yield. The results showed that water deficiency and absence of nitrogen fertilization decreased the accumulation and partitioning of various nutrients in plants. Although nitrogen fertilization led to increased nitrogen accumulation in tissues, it did not enhance yield significantly, while the highest seed yields were observed in plants under full irrigation regardless of nitrogen supplementation. However, deficient irrigation reduced the seed oil content in nitrogen-fertilized plants. In conclusion, nitrogen fertilization is crucial for nutrient homeostasis, and water availability affects biomass and nutrient accumulation, thus limiting soybean yield performance.
