Summary: Starch and sucrose showed opposing trends during dormancy release in P. kingianum rhizome bud, while galactose and raffinose increased. Glucose, cellulose, mannose, arabinose, rhamnose, and stachyose exhibited various changes. The metabolism of carbohydrates may shift from anaerobic oxidation to the tricarboxylic acid cycle and pentose phosphate pathway during dormancy release. Gene co-expression analysis indicated interactions between sugar and hormone signaling pathways in the regulatory network of dormancy release in P. kingianum rhizome buds.

Summary: This study determined the cellular polyglucan content in 27 cyanobacterial strains and found that the polyglucan contents were significantly enhanced under nitrogen and phosphate deprivation. The highest polyglucan accumulation was observed in Synechocystis under nitrogen deprivation, and it was likely mediated by the increased supply of glycogen synthesis substrates and metabolic inhibitions.

Summary: Energy metabolism is crucial in insect metamorphosis, particularly in the larval-pupal stage of holometabolous insects. In this study, metabolome and transcriptome analyses were conducted to elucidate the metabolic changes and regulatory mechanisms during larval-pupal metamorphosis of the cotton bollworm, Helicoverpa armigera. The findings revealed that aerobic glycolysis supported cell proliferation and lipid synthesis during the feeding stage, while triglyceride degradation and acylcarnitine accumulation were activated during non-feeding stages. This study provides valuable insights into the metabolic regulation mechanism of lepidopteran larvae during their final stage of development.

Summary: Flooding is a severe stress for plant growth and development. The mechanism of cotton tolerance to submergence stress is revealed through transcriptome analysis. Submergence stress regulates various stress-related genes and pathways, such as hormone signal transduction, starch and sucrose metabolism, and respiratory metabolism. The regulation of terpene biosynthesis by respiratory metabolism may enhance cotton's tolerance to submergence.

Summary: The study used event-related potentials (ERPs) to investigate the effects of carbohydrate (CHO) mouth rinsing on electrophysiological correlates of visuospatial attention. The results showed that CHO rinsing decreased the bottom-up controlled visuospatial attention (N1(pc)-ERP component) and increased the top-down controlled visuospatial attention (N2(pc)-ERP component) compared to non-nutritive sweetener (NNS) rinsing. However, behavioral performance was not affected. These findings suggest that orosensory signals can influence neurocognitive processes of visuospatial attention in a fasted state.

Summary: Alpha-synuclein is a protein associated with neural tissue and Parkinson's disease pathogenesis. The identification of similar transcript variants in pigs, with high expression in brain tissues and low expression outside the central nervous system, suggests potential for modeling the disease in pigs and studying genetic modifiers. The biophysical characteristics of porcine alpha-synuclein differ from its human counterpart, with reduced ability to bind to lipid vesicles and no observed fibrillation.

Summary: This study evaluated the simultaneous interferences of Cu and Zn in swine wastewater on the growth of microalgae in high rate algal ponds. It was found that specific concentrations of these metals promoted the growth of Chlorella sp. but higher concentrations inhibited it. Copper affected the removal rates of N-NH4+ while Zn interfered with Ps removal rates.

Summary: Heavy metals and their engineered nanoparticles are emerging contaminants that are known to impact plant growth and development. This critical review focuses on the effects of copper, iron, zinc, and manganese nanoparticles on food crops. Copper and manganese nanoparticles show similar impacts, while iron and zinc nanoparticles appear to be less toxic. Further research is needed to fully understand the physiological, metabolic, and molecular effects of nanoparticles and their ion counterparts on crop plants.

Summary: The plant kingdom contains a wide variety of bioactive compounds, some of which have health-supporting and industrial uses. The pepper plant, in particular, synthesizes many valuable compounds, and the leftover biomass from pepper production provides an opportunity to extract and utilize these metabolites. In addition, the synthesis of these compounds is induced as a defense mechanism against abiotic stresses.

Summary: This study aimed to identify ryegrass cultivars with contrasting phosphorus (P) use efficiency and assess their associated biochemical and molecular responses. Nine ryegrass cultivars were evaluated under optimal and P-deficient conditions, and the activity and gene expression of acid phosphatases (APases) and P transporters were analyzed. The results showed that cultivars with high P acquisition efficiency were influenced by root-related responses, while cultivars with high P utilization efficiency were influenced by P transporters and APase activity in shoots.

Summary: Plants in acidic soils are negatively affected by aluminum, leading to impaired root growth and reduced plant yield. Organic acids can improve metal tolerance but at a metabolic cost. In this study, different ecotypes of Arabidopsis thaliana showed varying reductions in root growth and reproductive yield in response to aluminum stress. The expression of the ALMT1 gene, associated with aluminum resistance, was high in all ecotypes. Further analysis revealed accumulation of diverse amino acids, carbohydrates, and organic acids in shoots and roots of some ecotypes under aluminum stress. Our findings suggest that the capacity for using and translocating reduced carbon molecules is crucial for overcoming aluminum stress.

Summary: The development of fleshy fruits involves changes in size, mass, cell differentiation, anatomical and histological changes, and metabolic alterations. The regulation of metabolism and its association with anatomical changes in non-climacteric fruit development are poorly understood. In this study, three developmental phases of chili pepper were defined, each marked by distinct metabolic profiles. Mitochondrial activity was high in the early stages of development and declined over time, with a respiratory-like burst at the beginning of the ripening stage.

Summary: The rupture of the Funda similar to o dam in Mariana-MG, Brazil resulted in iron ore tailings that impacted the Doce River basin, affecting the flora and fauna in the region. Plants in contaminated soil showed changes in metabolism, reduced growth and biomass, and phytotoxicity symptoms. However, some species were able to exclude or accumulate metals through adaptive strategies. In this study, we investigated the physiological and metabolic responses in Restinga shrub species affected by the mining plume from the contaminated sea. We found that the rainy season led to the accumulation of metals and higher levels of these metals at the sampling stations. Increased stomatal conductance and intercellular CO2 concentration were observed during the rainy season, which was characterized by high temperatures. The results showed correlations between metals and metabolic responses, indicating acclimation responses such as maintenance of photosynthesis, and accumulation of free amino acids, carbohydrates, and antioxidants. The differential physiological responses between the two species analyzed suggest a genetic load capable of partially responding to stressful conditions associated with the iron ore tailing plume.
