Summary: This study evaluated the protein quality traits of a pea population and identified several QTLs associated with protein concentration and digestibility. The results showed co-localization of certain QTLs with known QTLs for seed protein concentration. These findings are important for improving the nutritional quality of peas and enhancing their competitiveness in the plant-based protein market.

Summary: The mechanism of how glycine combined with urea affects the development of peach trees through nitrogen absorption and metabolism was investigated in this study. The results showed that the total dry weight of T5 and T2 significantly increased, while it was lower at T3. The root activity of T5 was significantly higher than CK. The residual NH4+ in the soil was consistent with the application ratio of urea, while the conversion of NO3- was promoted at T5. Additionally, T5 had higher soil amoA and nifH abundance, while T1 and T3 had higher nirK abundance. Nitrogen use efficiency had a very significant direct positive effect on the biomass of peach trees.

Summary: In this study, the multiconfigurational restricted active space self-consistent field RASSCF/RASPT2 method is coupled with the displaced harmonic oscillator (DHO) model to simulate soft X-ray spectroscopy. The method is applied to various second-row elements and small organic molecules, showing sub-eV accuracy in simulating X-ray absorption near-edge structure (XANES) and X-ray photoelectron spectroscopy (XPS). The method is sensitive to spectral shifts in fluorinated ethylene systems, distinguishes stable conformers of the glycine molecule, and accurately captures the vibrationally resolved carbon K-edge spectrum of formaldehyde. Comparisons with other theoretical methods highlight the advantages of using a multireference/multiconfigurational approach.

Summary: This study investigated the effects of the coapplication of organic and inorganic nitrogen on maize plant growth, nitrogen metabolism, and soil nitrogen content. The results showed that the coapplication of glycine and inorganic nitrogen increased shoot nitrogen uptake and root growth in maize. Additionally, the coapplication of glycine and inorganic nitrogen promoted nitrogen metabolism levels and the accumulation of amino acids and soluble protein in leaves.

Summary: The restriction of calories, branched-chain amino acids, and methionine have been shown to extend lifespan in model organisms. Recently, glycine was found to boost longevity in genetically heterogenous mice. This simple amino acid similarly extends lifespan in rats and improves health in mammalian models of age-related disease. Existing evidence suggests that glycine prolongs life by mimicking methionine restriction and activating autophagy.

Summary: This retrospective study evaluated the energy and nutrient intake of dogs in a weight loss program. The study divided 94 obese dogs into three groups based on the percentage of body weight loss they achieved. The study analyzed five brands of kibble diets designed for weight loss and compared their nutrient content. The study found that despite the high nutrient concentrations in the diets, the actual intake of several nutrients was lower than recommended due to the reduced energy allowance.

Summary: The aim of this study was to increase the yield and quality of purple lettuce while lowering its nitrate level. The results showed that adding 20 mu mol m(-2) s(-1) UV-A and a NO3--N/NH4+-N ratio of 3/1 significantly reduced the nitrate level and increased the growth and quality of purple lettuce. The purple leaf lettuce also exhibited improved nitrogen absorption and metabolism, leading to increased biomass synthesis.

Summary: Previous work has shown that dietary supplementation with key functional amino acids (FAA) improves growth performance and immune status of disease-challenged normal birth weight (NBW) pigs. This study aimed to investigate the effects of birth weight and FAA supplementation on Salmonella-challenged pigs. The results showed that FAA supplementation can attenuate the effects of Salmonella infection in NBW pigs, but not in low birth weight (LBW) pigs.

Summary: Short-range non-covalent interactions between amino acid residues play a crucial role in determining protein structures and functions. The interactions between the thioether of methionine and the aromatic rings of tyrosine, tryptophan, and/or phenylalanine are highly favorable. A new bioinformatics survey of protein structures reveals the presence of clusters formed by the localization of these aromatic residues around the methionine thioether. These clusters, known as 3-bridge clusters, show a network of interactions involving the methionine sulfur, methylene, methyl groups, and nearby aromatic residues. The findings suggest potential functional roles of 3-bridge clusters in proteins.

Summary: The study found that low nitrogen supply significantly affects carbon metabolism, amino acid metabolism, and phenolic biosynthesis metabolism in lettuce, leading to a significant increase in phenolic content. This suggests that low nitrogen treatment may effectively redirect carbon and nitrogen resources to the phenolic biosynthesis pathway, thereby increasing the phenolic accumulation in lettuce.

Summary: This study tested the effect of various temperatures on four species of the Spodoptera complex, finding that Spodoptera eridania prefers moderate temperatures while Spodoptera albula may thrive in warmer regions. Spodoptera frugiperda and S. cosmioides showed a wider temperature range for development, with S. frugiperda displaying higher biological potential across all evaluated temperatures. The data produced can assist in predicting outbreaks of these pests and understanding their spatial distribution.

Summary: On-farm soybean yield has significantly increased in southern Brazil over the past 50 years. This study evaluated the changes in yield improvement and associated agronomic attributes of soybean cultivars released in the region. The results showed that increased seed number per area and harvest index were the main factors contributing to yield increase. Meanwhile, cultivars became less susceptible to lodging and plant mortality reduced. Seed oil concentration increased, while seed protein concentration decreased. These findings have important implications for soybean utilization and future breeding efforts.

Summary: The antimicrobial and biochemical activity of Aloysia citriodora essential oil in controlling Alternaria linariae was evaluated. In vitro tests showed that a dose of 2.4 μL mL(-1) inhibited A. linariae growth, while a dose of 2.5 μL mL(-1) reduced disease severity in vivo. Essential oil application induced resistance against tomato black spot fungus through β-1,3 glucanase enzyme activity. The use of A. citriodora essential oil shows promise for controlling black spot fungus and promoting sustainable agriculture.

Summary: This study aimed to determine novel options for selective, post-emergence chemical weed control in black oat fields. Through field and greenhouse trials, it was found that mesotrione could be an effective selective herbicide for black oat fields. Some herbicide treatments caused light crop phytotoxicity symptoms, but plants quickly recovered.

Summary: The study evaluated the performance of maize genotypes with different canopy architecture in Southeast Brazil under different spatial arrangements. Increasing plant density led to higher plant height and ear insertion height, as well as increased absorption of photosynthetically active radiation and leaf area index. The upright leaf hybrid DKB 230 showed greater yield potential compared to the semi-upright leaf hybrid DKB 390.
