Recent findings suggest that the mitochondrial thioredoxin (mTRX) system can coordinate metabolic fluxes from the tricarboxylic acid (TCA) cycle toward glutamate and glutamine in a mechanism apparently independent of the redox status of GS. It remains unclear whether this mechanism involves GOGAT and glutamate dehydrogenase (GDH), other enzymes involved in glutamate metabolism. Here, we carried out bioinformatics and biochemical analyses to investigate how the absence of TRXs affects the enzyme activity of GOGAT and GDH in leaves harvested at the end of the day (ED), end of the night (EN), and after a short high-light (HL) period. We used plants lacking TRX <em>o1</em> (<em>trxo1</em>), TRX h2 (<em>trxh2</em>), or both NADPH-dependent TRX reductase A and B (<em>ntrab</em>), alongside wild-type (WT) plants. Molecular docking revealed multiple stable interaction modes between TRX <em>o1</em> and GOGAT, GDH1, and GDH2. The lowest-energy clusters indicate high-affinity binding, with distinct hotspots identified for each enzyme. These results suggest that TRX <em>o1</em> may engage in several energetically favorable conformations relevant to functional or regulatory interactions. The activity of GOGAT and GDH was lower in both <em>trxo1</em> and <em>ntrab</em> mutant lines at ED. In addition, <em>trxo1</em> mutants exhibited a reduction in the potential quantum yield of PSII under HL stress, accompanied by higher activities of GOGAT and GDH compared with WT plants under HL conditions.

Biopesticides play a key role in agroecological transitions, offering environmentally sound and residue-free solutions for postharvest disease management. Despite significant research advances, the global innovation landscape for postharvest biopesticides remains poorly understood (i.e., the geographic distribution, technological maturity, and institutional drivers of this innovation have not been systematically mapped), limiting large-scale adoption and policy integration. Understanding patent activity provides valuable insight into technological trends, innovation drivers, and regulatory barriers shaping the development of these green technologies. Here, we review the global patent landscape for postharvest biopesticides, based on 251 patent families retrieved from Espacenet and INPI databases without time restriction. The main points are as follows: (1) the innovation field is rapidly evolving and strongly driven by research institutions, with universities responsible for 59% of all filings; (2) China leads patenting activity (45%), followed by the United States, reflecting regional asymmetries in technological capacity; (3) microbial biopesticides dominate the landscape, particularly <em>Bacillus spp</em>., which account for 26% of all identified biocontrol agents; (4) the main target pathogens (<em>Botrytis cinerea</em>, <em>Penicillium expansum</em>, and <em>P. digitatum</em>) are responsible for major postharvest losses in apples, tomatoes, and pears; and (5) integrated formulations combining microbial, biochemical, and chemical components represent 26% of filings, highlighting efforts to enhance product efficacy and stability through synergistic strategies. However, large-scale adoption remains limited by regulatory complexity, short shelf life, inconsistent field performance, and weak technology transfer from academia to industry.

Its pyrogenic nature has prompted comparisons to biochar for agricultural soil amendment, which motivates proactive assessment of its potential impacts on microbial ecosystem services such as nitrogen (N) cycling. Past research with pure bacterial cultures suggested that ZVC could inhibit nitrification, which would enhance soil retention and plant utilization of applied N fertilizers. Here, we conducted soil microcosm studies to verify this effect in a more realistic system and determine whether it may translate to climate benefits by decreasing soil nitrous oxide (N<sub>2</sub>O) emissions. ZVC-amended microcosms were prepared with clay or sandy soils to assess response variability, and biochar-amended microcosms were included for benchmarking. ZVC hindered nitrification in both soils, resulting in lower N<sub>2</sub>O cumulative fluxes by up to 15 ± 2% compared to unamended controls.
