Phylogenetic reconstruction reveals five conserved clades, while synteny analysis demonstrates that segmental duplications, followed by strong purifying selection, drove the family expansion, implying functional constraints.

Maize-legume intercropping is an established practice that can effectively improve resource use efficiency and land productivity. However, current research remains limited regarding the combined effects of row orientation and balanced NPK fertilization on intercropping systems. This study was carried out to investigate the impacts of row orientation and NPK application rate on the agronomic performance, productivity and economic return of a maize-soybean intercropping system under the agroecological conditions of Bangladesh. A field experiment was conducted using a split-plot design, with two row orientations [North-South (N-S) and East-West (E-W)] arranged as main plots, and four NPK application rates [0% (F₀), 75% (F₁), 100% (F₂), and 125% (F₃) of the locally recommended NPK rate] arranged as subplots. We measured a range of indicator parameters including plant growth traits, yield components, grain yield, land equivalent ratio (LER), maize equivalent yield (MEY) and economic returns. The results showed that row orientation had negligible effects on maize growth and grain yield, but exerted a significant influence on soybean performance. Compared with the E-W orientation, the N-S orientation produced higher soybean grain yield (1.11 t ha⁻¹), higher harvest index, and higher maize-equivalent yield (12.25 t ha⁻¹). Increasing NPK application rate significantly promoted the growth, yield components, grain yield and stover yield of both maize and soybean. The highest grain yields of maize (12.68 t ha⁻¹) and soybean (1.47 t ha⁻¹) were recorded in the F₃ treatment. The highest LER (2.25) was observed in the N-S × F₃ combination. Economic analysis further demonstrated that the F₃ treatment achieved the optimal economic performance, with the highest gross return (BDT 480,537 ha⁻¹), net return (BDT 233,124 ha⁻¹) and benefit-cost ratio (1.94). This study concludes that the highest agronomic performance, land use efficiency and economic return of maize-soybean intercropping in the study region can be achieved when adopting North-South row orientation and applying 125% of the recommended NPK fertilizer rate.</div></div>","PeriodicalId":34095,"journal":{"name":"Oil Crop Science","volume":"11 3","pages":"Pages 265-276"},"PeriodicalIF":4.4,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149006628","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We critically analyze the key structural features and assembly pathways, highlighting noncovalent interactions (hydrogen bonding, hydrophobic forces, electrostatic attraction, π-π stacking) and covalent oxidative coupling.

Emerging fabrication strategies and integrated characterization approaches are summarized. Furthermore, we discuss how the strategic combination of binary interactions leads to emergent properties in ternary systems, such as enhanced interfacial stabilization and controlled release, enabling innovative applications in food emulsions, nutraceuticals, drug delivery, and biomaterials.

Recent advances in oil crop breeding have improved oil content, yet how climate variability undermines the realization of these gains remains insufficiently understood. Here, we compiled 16,424 production-scale observations of winter rapeseed oil content from the Yangtze River Basin during 2008 to 2022 and used a stage-resolved analytical framework to quantify climate-associated constraints on realized oil content gains. Rapeseed oil content showed a significant long-term upward trend, with an ordinary least squares slope of 0.24% per year. However, climate effects increasingly reduced the realized gains over time: the mean signed climate contribution exacerbated from -0.01% (2008- 2012) to -1.06% (2013 - 2017) and further to -1.75% (2018- 2022). Extreme heat exposure was negatively associated with oil content, and the strongest effect was observed in the middle reaches of the Yangtze River, where the coefficient for extreme degree days reached -0.06. Stage-specific and SHapley Additive exPlanations (SHAP) based analyses showed that the declines in oil content were mainly associated with heat and moisture related signals during key developmental periods. Flowering exhibited the greatest climate sensitivity, with the largest median permutation-induced R² decline of 0.469.
