Ammonium transporters (AMTs) are vital plasma membrane proteins facilitating NH4+ uptake and transport, crucial for plant growth. The identification of favorable AMT genes is the main goal improving ammonium-tolerant algas. However, there have been no reports on systematic expression analysis Chlamydomonas reinhardtii (C. reinhardtii) genes. This study comprehensively identified eight CrAMT genes, distributed across chromosomes, all containing more than 10 transmembrane structures. Phylogenetic revealed that CrAMTs belonged to AMT1 subfamily. conserved motifs domains were similar those members OsAMTs AtAMTs. Notably, gene fragments longer contain introns compared AtAMTs OsAMTs. And promoter regions enriched with cis-elements associated hormones light response. Under treatment, CrAMT1;1 CrAMT1;3 significantly upregulated, while CrAMT1;2, CrAMT1;4, CrAMT1;6 saw a notable decrease. CrAMT1;7 CrAMT1;8 also experienced decline, albeit less pronounced. Transgenic algas overexpressed did not show significant difference in growth CC-125, transgenic knockdown exhibited inhibition. or knocked-down displayed reduced which resulted suppression other None showed better CC-125 at high ammonium levels. In summary, our has unveiled potential role high-ammonium environments can serve as foundational research platform investigating algal species.

Unlocking the potential of sustainable agriculture relies on innovative approaches such as recycling crop waste and exploiting wastewater. Herewith, human urine derivatives were integrated into fertigation soilless-grown lettuce. The effects remarkable: not only did they impact primary metabolites amino acids, proteins, sugars, but also influenced secondary polyphenols anthocyanins, along with antioxidant enzyme activity. K-struvite, a precipitate CaO NaOH, elicited responses comparable to those control NPK correlated high biometric values. Interestingly, precipitate–CaO electrodialysis (ED) concentrate stimulated accumulation leaf while induced ABTS capacity, highlighting their enhance activity nutritive quality. Moreover, hydrolyzed aurin significant boost essential acid content, underlining role in increasing value However, higher levels MDA, marker lipid peroxidation, reduced APX activity, indicating need for further optimization. These findings underscore promising an organic component soilless lettuce fertilization, paving way more resource-efficient agricultural practices.

Biochar is frequently utilized as a helpful amendment to sustain agricultural productivity. However, it remains uncertain whether biochar can effectively replace chemical fertilizers, especially in karst regions. To investigate the effects of co-applying and fertilizer on biological characteristics uptake pod peppers, well determine optimal ratio two-year field experiment was conducted southwest China. The results showed that, compared locally typical treatment (CF), combined application significantly increased yield both fresh dry pepper. Chemical reduction also ameliorated fruit quality, nutrient accumulation, improved utilization efficiency. What more, although employment made production costs higher, fertilizers increase economic efficiency, CF70B (70%CF + biochar). In conclusion, moderate amounts instead may be valid management strategy for pepper mountain areas, which beneficial maintaining stability, improving increasing net income.

The use of slow-release fertilizers and seed-fertilizers cause localized high-ammonium (NH 4 + ) environments in agricultural fields, adversely affecting wheat growth development delaying its yield. Thus, it is important to investigate the physiological responses tolerance NH stress improve adaptation high environments. In this study, mechanisms ammonium ( Triticum aestivum were investigated depth by comparative analysis two cultivars: -tolerant Xumai25 -sensitive Yangmai20. Cultivation under hydroponic conditions with (5 mM , AN) nitrate NO 3 - NN), as control, provided insights into nuanced both cultivars. Compared Yangmai20, displayed a comparatively lesser sensitivity stress, evident less pronounced reduction dry plant biomass milder adverse impact on root morphology. Despite similarities efflux expression levels TaAMT1.1 TaAMT1.2 between cultivars, exhibited higher influx, while maintaining lower free concentration roots. Furthermore, showed more increase amino acids, including asparagine, glutamine, aspartate, suggesting superior assimilation capacity compared Additionally, enhanced transcriptional regulation vacuolar glucose transporter metabolism contributed an carbon skeleton supply, particularly 2-oxoglutarate pyruvate. Taken together, our results demonstrate that intricately linked optimized transport, which contributes robust capacity.

Soil properties can affect plant population dynamics and the coexistence of native invasive plants, thus potentially affecting community structure invasion trends. However, different impacts soil physicochemical on species diversity in invaded communities remain unclear. In this study, we established a total 30 Alternanthera philoxeroides-invaded plots control an area at geographical boundary between North South China. We compared differences composition communities, then used methods regression analysis, redundancy analysis (RDA), canonical correspondence (CCA) to examine four α-diversity indices distribution these two types communities. found that A. philoxeroides increased difference importance values dominant species, coverage had negative relationship with soil-available potassium (R2 = 0.135; p 0.046) Patrick richness index 0.322; < 0.001). was determined chemical properties, index, Simpson dominance Shannon–Wiener which all decreased increase pH value, available potassium, organic matter, ammonium nitrogen. by physical properties; Pielou evenness increasing non-capillary porosity but capillary porosity.

Nitrogen fertilizers in agriculture often suffer losses. Ammonia-assimilating bacteria can immobilize ammonia and reduce these losses, but they have not been used agriculture. This study identified an ammonia-assimilating strain, Enterobacter sp. B12, which assimilated via the glutamate dehydrogenase (GDH) pathway at low levels (5 mM) glutamine synthetase (GS)-glutamine-2-oxoglutarate aminotransferase (GOGAT) high (10 mM). Inoculating wheat with B12 increased seedling dry weight, nitrogen accumulation, rhizosphere soil content, root enzyme activities, including GDH, superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), under both conditions. However, GS, GOGAT assimilation-related gene expressions were lower than controls. The results suggest that bacterium promotes growth, immobilization by establishing amino acid exchange roots enhancing antioxidant capacity, making it a potential plant growth-promoting rhizobacteria (PGPR).
