Increasing research on SW has focused on the SQUAMOSA promoter binding protein-like (<em>SPL</em>) family, making the <em>SPL</em> genes a primary target in our study. We conducted a whole-genome analysis of eight rapeseed varieties, identifying 72 <em>BnaSPL</em> genes, which include 53 core genes, 14 dispensable genes, and five specific genes. Based on evolutionary relationships, these <em>BnaSPL</em> genes were classified into six subgroups. An evaluation of Ka/Ks values revealed that seven <em>BnaSPL</em> genes are under positive selection, while 44 are subject to purifying selection. Expression profiling across different tissues and qRT-PCR analysis confirmed that 26 <em>BnaSPL</em> genes are highly expressed during seed development. Further analysis indicated that eight genes exhibit variations in structure and motifs across at least two rapeseed varieties, although all retain conserved SBP domains. The diversity in cis-acting elements suggests potential functional variability among these genes. Haplotype analysis of 2311 germplasm resources identified four key genes—<em>BnaSPL2–3</em>, <em>BnaSPL3–3</em>, <em>BnaSPL7–4</em>, and <em>BnaSPL16–4</em>—whose haplotypes were associated with differences in thousand-seed weight (TSW) and yield across rapeseed varieties. Notably, these yield increases were stable and unaffected by external environmental factors, such as low or high salinity stress. Our findings underscore the potential of <em>BnaSPL2–3</em>, <em>BnaSPL3–3</em>, <em>BnaSPL7–4</em>, and <em>BnaSPL16–4</em> in breeding rapeseed varieties with higher TSW and yield.</div></div>","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"232 ","pages":"Article 121237"},"PeriodicalIF":5.6,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144212651","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}

Results demonstrated significantly higher ¹⁵N uptake rates (6.26 %-120.79 %) in roots, trunks, branches, and leaves under urea treatment compared to compound fertilizer.

Molecular analysis revealed divergent microbial mediation-both fertilizers enhanced soil N mineralization but through distinct biochemical pathways: urea primarily stimulated assimilatory nitrate reduction (upregulating <em>nasB</em>, <em>nasA</em>, <em>nasD</em> and <em>nirA</em> genes), whereas compound fertilizer activated dissimilatory pathways (<em>nirB</em> gene upregulation). These findings elucidate the physiological basis of N utilization preferences in poplar, demonstrating root system modularity where lower-order roots specialize in nutrient acquisition while higher orders focus on transport.

The objective of this study was to determine seed germination and vigor of spring camelina (C046) and winter camelina (Joelle) under salinity and sodicity. A set of 50 seeds and a subset of 15 seeds were germinated in Petri dishes saturated with of NaCl, CaCl₂, and Na₂SO₄ solutions at concentrations of 0, 40, 80, 120, and 160 mM L⁻¹, in an incubator set to a constant temperature of 20°C. The experimental design was a randomized complete block with three replicates. Germinated seeds were counted daily for 7 days. With the exception of seedling dry weight and hypocotyl length, the winter biotype of camelina produced significantly lower values for measured parameters than the spring biotype. Averaged across varieties and salt concentrations, Na₂SO₄ reduced germination, vigor, and seedling dry weight more than NaCl and CaCl₂. In addition, Na₂SO₄ almost completely inhibited radicle and hypocotyl growth at concentrations &gt; 80 mM L⁻¹. This is of significance, because Na₂SO₄ is commonly present in sodic soils in the northern Great Plains and sodium is known to disrupt soil structure and reduce water infiltration, which can inhibit root growth.

This study aimed to evaluate the effect of ACP on 5-Fluorouracil (5-Fu)–induced intestinal mucositis (IM) and investigate its mechanisms of action. The anti-IM effect of ACP was investigated in C57BL/6 mice. Transcriptomics, western blot and enzyme-linked immunosorbent assay were used to detect its anti-inflammatory mechanism. 16sRNA sequencing, short-chain fatty acid analysis, fecal microbiota transplantation, and non-targeted metabolome detection were used to determine the impact of ACP on the metabolism of gut microbiota. The average molecular weight of ACP was 5.25 × 10³ Da, and ACP mainly comprised Arabinose, Galactose, Glucose, Galacturonic acid, and Mannuronic acid. ACP (25 and 50 mg/kg) significantly mitigated weight loss, colon shortening, and pathological injuries caused by 5-Fu treatment in mice. Moreover, ACP administration reduced the levels of inflammatory cytokines of IL-1β, TNF-α, and IL-6, within the colon, potentially through the inhibition of the NLRP3/NF-κB signaling pathway. Furthermore, changes in the abundance of several genera were closely associated with the efficacy of ACP in mitigating intestinal inflammatory responses. Meanwhile, ACP (50 mg/kg) significantly reversed the changes of acetic acid, hexanoic acid, and butyric acid levels in feces. Glycerophospholipid, purine, choline and glycerolipid metabolism pathways may contribute to the anti-IM effect of ACP. ACP may possess a potential to alleviate 5-Fu-related IM by modulating gut microbiota, regulating multiple metabolic pathways, and exerting anti-inflammatory effects.</div></div>","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"232 ","pages":"Article 121312"},"PeriodicalIF":5.6,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144212539","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}
