The appropriate application of nitrogen fertilizers and biochar to the soil is beneficial for soybean growth, a combination can improve low-nitrogen fertilizer utilization efficiency. However, effect on roots still unclear. Therefore, in this study, we investigate changes endophytic bacterial communities metabolites under different combinations treatments by setting fertilization levels using high-throughput sequencing non-targeted metabolomics techniques. results showed that applying 20 t/ha 180 kg/ha (C2N1) resulted highest yield. By studying community roots, it was observed dominant phyla were Proteobacteria, Bacteroidota, Actinobacteriota, genera Bradyrhizobium, Streptomyces, Rhizobacter. Moreover, metabolic pathway analysis revealed glycosylphosphatidylinositol (GPI)-anchor biosynthesis most significant C0N1 vs. C0N0 comparison group, glycerophospholipid metabolism C2N1 C1N1 group; they both associated with regulatory mechanisms such as plant growth promotion nutrient cycling. Structural equation modeling indicates bacteria have positive impact Bradyrhizobium Rhizobium are observable variables effects bacteria, while Phe-Thr 7-allyloxycoumarin metabolites. Endophytic not only direct crop yield, but also indirectly affect yield through their This study has important scientific value guiding significance improving yields.

Auxin has emerged as a crucial regulator of plant nitrogen (N)-use efficiency (NUE) through indirect effects on growth and development direct regulation N metabolism-related genes. We previously reported DULL NITROGEN RESPONSE1 (DNR1) an amino transferase that inhibits auxin accumulation negatively regulates rice (Oryza sativa) NUE grain yield. However, the identities molecular regulators acting upstream DNR1 await exploration. Our current work identifies SUPPRESSOR OF ON CHROMOSOME 5 (SOD5) from suppressor mutant. SOD5 encodes v-myb avian myeloblastosis viral oncogene homolog (MYB) transcription factor directly binds to promoter, activating its expression further repressing accumulation. Knocking out significantly increases yield, especially under low conditions. Therefore, targeting offers promising strategy for enhancing crop performance, supporting crops better suited sustainable agriculture.

Shaping the canopy architecture and delaying leaf senescence in maize are pivotal strategies for extending crop’s photosynthetic period improving yield. The application of plant growth regulators (PGRs) is a critical cultivation measure, with timing being paramount importance. To explore effects PGR time on structure, characteristics yield, comparative two-year field study was undertaken during 2019–2020 growing seasons at Gongzhuling Experimental Station Jilin Academy Agricultural Sciences, utilizing containing ethephon as active ingredient. experiment structured two densities 60,000 90,000 plants ha−1, three distinct protocols: T10 (application 10th stage), T15 15th CK (control group sprayed water). result indicated that yield increased by 5.62% following treatment compared to under high density (90,000 ha−1). Furthermore, kernel per ear 1000-kernel weight 3.93% respectively, while abortion rate decreased. Correlation analysis showed components were correlated morphology, physiology, aging ha−1.

Improving poplar productivity across a wide spectrum of nitrogen conditions is primary objective in breeding. In this research, we engineered transgenic poplars to overexpress the aspartate aminotransferase 10 (AspAT10) gene. The results showed that these plantlets significantly outperformed wild-type control terms growth under both nitrogen-poor and nitrogen-rich conditions, exhibiting increased biomass, height, root development. This improvement was linked changes internal pools (including NO3-, NH4+, total free amino acids) sugar content. line with metabolic results, notable alterations genes related carbon metabolism as well hormone signaling pathways were identified. Our findings highlight versatile role AspAT10 regulating poplar's adaptation variable availability, attributed reversible nature its catalytic reaction, which allows for flexible reprogramming align supply plant demand.

Nitrogen (N) is a key nutrient which affects plant development and quality formation for tea plants. Notable genetic variation in nitrogen use efficiency (NUE) has been reported among different genotypes of Camellia sinensis. However, the molecular mechanisms underlying these differences have not illuminated. In this study, 15N tracing method was used to compare six genotypes. The results show that there were significant NUEs Among them, TC12 had highest NUE, while LJCY lowest NUE. Transcriptome analysis between two cultivars showed differentially expressed genes (DEGs) significantly enriched photosynthesis—antenna proteins zeatin biosynthesis mature leaves new shoots, respectively. higher expression levels AMT1.2, NRT2.4, NRT3.2 roots, AAP6 AAP7 stems LHC than LJCY.
