Summary: The study evaluated the impact of two herbicides on symbiotic nitrogen-fixing bacteria and found that at high doses, the herbicides decreased nodule number, size, weight, nitrogen content, and symbiotic efficiency. The research demonstrates that the reduced growth of herbicide-treated plants was directly caused by the effects on rhizobia, rather than indirect effects on the plants themselves.

Summary: The use of food-processing wastewaters to produce microbial biomass-derived single cell protein (SCP) is a sustainable way to meet the global food demand. Microbial community-based approaches to SCP production have the potential benefits of lower costs and greater resource recovery compared to pure cultures, yet they have received scarce attention. In this study, SCP production from soybean-processing wastewaters using their existent microbial communities was evaluated, and the results showed that reactors produced more SCP when fed with wastewaters of higher soluble total Kjeldahl nitrogen (sTKN) content.

Summary: In this study, theoretical investigations were conducted to obtain collision data between nitrogen (N) and nitrogen ion (N+), including scattering cross sections and collision integrals. The potential energy curves of N2+ were obtained using the ab initio method and used to calculate resonant charge exchange and elastic cross sections. The collision integrals for N(S-4)-N+(P-3) and N(S-4)-N+(D-1) interactions were computed, revealing the importance of elastic collision process at low temperatures. This is the first calculation of cross sections and collision integrals for the N(S-4)-N+(D-1) interaction using ab initio potential energy points, and the obtained results are crucial for modeling the transport properties of related plasmas.

Summary: Metabolomics plays a crucial role in cancer mechanism and early diagnosis, with enantioanalysis of amino acids in biological samples potentially improving screening tests for early cancer detection. Novel stochastic biosensors utilizing alpha-hemolysin and hemin immobilized in graphene modified with nitrogen and sulfur show promise for enantioanalysis of aspartic acid in biological samples, demonstrating high sensitivity and stability.

Summary: This study investigates the presence and role of OsAAP1 transporter in various organs and tissues of rice plants. The loss of OsAAP1 function in mutant lines led to reduced growth and grain yield, as well as decreased absorption, use, and remobilization of nitrogen. The distribution of amino acids was affected in the mutant lines, resulting in accumulation in vegetative organs. Additionally, the fertility of spikelets was severely reduced. These findings highlight the critical role of OsAAP1 in amino acid translocation, spikelet fertility, and grain yield maintenance in rice.

Summary: In this study, an innovative method for artificially synthesizing alpha-amino acids from nitric oxide (NO) was demonstrated. The process involved electrocatalytic reactions with alpha-keto acids using an atomically dispersed Fe supported on N-doped carbon matrix (AD-Fe/NC) catalyst. The conversion of nitrogen oxides into high-value products was achieved through a series of reactions, including the conversion of NO into hydroxylamine and subsequent nucleophilic attack on the alpha-keto acid. This research not only contributes to the artificial synthesis of amino acids but also promotes the development of near-zero-emission technologies for global environmental and economic advancement.

Summary: This study investigated the effects of maize-soybean intercropping on nitrogen uptake, yield, utilization efficiency, and nitrogen assimilatory enzymes of maize crops under different nitrogen fertilization conditions. The results showed that intercropping at the optimal nitrogen rate significantly increased maize grain yield, residue yield, and 100-grain weight in both years. Intercropping also improved nitrogen content and uptake, as well as the activities of nitrogen assimilatory enzymes. These findings highlight the potential of intercropping for enhancing nitrogen status and use efficiency in maize crops, supporting sustainable agricultural production.

Summary: The aim of this study was to investigate if changes in plasma essential AA concentration or profile can serve as an indicator of EAA status in cows. Different plasma EAA profiles were found to be associated with lactating cow performance, feed efficiency, and N utilization, indicating potential differences in EAA utilization by cows with different milk output and efficiency levels.

Summary: Long-term non-fertilization leads to minimal availability of nitrogen in the soil, which affects the yield and quality of tea. Lower nitrogen application promotes the biosynthesis of specific amino acids, including theanine and glutamate, while higher nitrogen application enhances flavonoid synthesis.

Summary: Increasing nitrogen use efficiency (NUE) is crucial for enhancing cereal yields, improving grain quality, and reducing agrochemical inputs. However, achieving enhanced NUE faces challenges such as poor synchronization between N supply and demand, low grain yields per unit of N input, and trade-offs between grain yield and quality. To address these challenges, this study focuses on the temporal perspective of NUE related processes at different growth stages and proposes the utilization of beneficial microbes, particularly arbuscular mycorrhizal fungi (AMF), for their roles in affecting NUE at the later development stages. It suggests exploring AMF and their potential roles in promoting NUE related processes after anthesis and proposes approaches for plant breeding and crop management to fully exploit the opportunities for beneficial root-fungal symbiosis.

Summary: The study examined the effects of growth media made of peat and different domestic materials on tomato nutrition, growth, and yield as an alternative to cocopeat in Turkiye. It was found that using vermicompost and its mixtures with peat as growth media resulted in the highest leaf and fruit nutrient concentrations. The highest fruit yields and biomass weights were obtained with solely peat and 1:1 peat + vermicompost medium. Peat-containing growth media, especially peat + vermicompost mixtures, can be used as alternatives to cocopeat in soilless tomato cultivation.
