Tung tree can accumulate oil even during late-stage seed maturation under cold waves. Understanding unsaturated fatty acid formation in tung tree under low temperatures is crucial. Previous research identified three types of fatty acid desaturases in plants, but their roles in tung tree remain unclear. Our study shows that <em>VfSCD</em>, a stearoyl-CoA desaturase in tung tree, increases oil content and enhances cold tolerance by promoting unsaturated fatty acid accumulation. <em>VfSCD</em> is highly expressed in leaves and developing seeds, correlating with increased oil and unsaturated fatty acids. Localization studies reveal VfSCD in the endoplasmic reticulum. Heterologous overexpression of <em>VfSCD</em> in <em>E. coli</em>, yeast, and tobacco increases oil content by raising unsaturated fatty acids while reducing saturated ones. Knockdown of <em>VfSCD</em> decreases oil content due to reduced unsaturated fatty acids. Overexpression of <em>VfSCD</em> also improves tobacco's cold tolerance, similar to wild-type plants under low temperatures. In summary, we propose that, in addition to the stearoyl-ACP desaturase (SAD) pathway in plastids, a distinct pathway regulated by VfSCD in endoplasmic reticulum of tung tree enhances cold tolerance by increasing unsaturated fatty acid contents.</div></div>","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"232 ","pages":"Article 121306"},"PeriodicalIF":5.6,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144202320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As dozens of silk fibre type exist, comprehensive understanding and comparison of their characteristics are crucial for fibre selection, and the hybrid of different silk fibres may provide better overall characteristics and open up new opportunities for their applications. This paper focused on the properties of <em>Bombyx</em> (BM) and <em>Antheraea Pernyi</em> (AP) silk fibre hybrid composites. Their mechanical and thermal properties, as well as the temperature influence from −50–60 °C were investigated. From experimental results, more BM silk fibres provided higher modulus and strength, while higher AP silk content could improve the impact toughness for silk fibre composites (SFCs) in general. Additionally, all mechanical properties of SFCs showed greater sensitivity to temperature change as the increase of AP silks within the composites on the whole. Damage mechanism studies demonstrated the hierarchical micro-fibre slippage and dissociation of AP silk fibres during their fracture process, which could promote the energy absorption during composite mechanical testing, and these mechanisms were more notable as temperature rose. In summary, the hybrid 8AP+ 4BM SFCs exhibited more favourable performance than both pure AP and BM SFCs, with tensile strength, modulus and impact strength reaching 96 MPa, 5.4 GPa and 64 kJ/m² respectively (at 23 °C), plus the glass transition temperature of 95 °C.

Hook.), a key subtropical plantation species in China, suffers severe soil degradation under monoculture systems, evidenced by productivity decline and nutrient depletion. Mixed forests enhance nutrient availability and microbial function. However, systematic optimization of species configurations of mixed forests remains unexplored. In this study, based on a 30-year-old Chinese fir plantation (retained density: 225 trees/ha), four treatments were established with a tree ratio of 3:7 (Chinese fir to planted species): mixed planting a <em>Phoebe bournei</em> (M1) understory; planting a <em>Phoebe bournei</em> and <em>Taxus wallichiana var. chinensis</em> understory (M2); planting a <em>Phoebe bournei</em>, <em>Taxus wallichiana</em> var. <em>chinensis</em>; planting a <em>Schima superba</em> understory (M3); and a pure plantation of Chinese fir (M0). This study analyzed biotic factors (enzyme activity, microbial metabolic limitations, and community structure), abiotic factors (chemical properties and stoichiometric ratios), and soil quality to select the optimal tree species mixture configuration. Mixed planting significantly enhanced soil nutrient levels, balances stoichiometric constraints, optimizes enzyme activities and microbial diversity, and improved soil quality. Mixed planting showed 29.9–72.6 % higher TN, TP, AN, AK, and SOC in the 0–20 cm layer versus monoculture. Hydrolytic enzymes (sucrase, urease and β-1,4-glucosidases) activity peaked in mixed forests, while monoculture (catalase activity) exhibited elevated oxidative enzymes. M2 had the highest soil quality index (SQI). M2 reduced phosphorus limitation by 12.1 % and alleviated subsoil carbon constraints and increased nitrogen hydrolyses activity. Microbial diversity and keystone taxa were enriched in mixed forests, driven by tree configuration effects on total phosphorus (path=0.68), N/P ratio (0.71), SOC (0.33), pH (0.34), and microbial diversity (0.60). Among the treatments, M2 optimally restores degraded monoculture by balancing SOC accumulation, microbial diversity, and phosphorus availability.
