Artificial induction of polyploidy is an effective strategy to improve crop yield, but it has been less applied in castor bean and underlying mechanisms remain unclear. Here, we developed a tetraploid castor bean by colchicine induction with the enhancement of seed traits, including seed size, weight and oil content. Histological analysis showed that the increased seed size in tetraploid castor may cause by the increased cell size. Combined with transcriptome analysis, we identified many key genes involving into the hormonal signaling network, especially brassinosteroid and cytokinin, which may have the potential function in regulating seed size and weight in tetraploid castor. Meanwhile, we noted that many genes encoding key enzymes participating in glycolysis, fatty acids synthesis and triacylglycerol assembly were significantly up-regulated in tetraploid castor seeds as compared with diploid ones. Importantly, DAP-seq (DNA affinity purification sequencing) analysis showed that transcription factor WRINKLED1 might serve as a crucial regulator driving seed oil synthesis in tetraploid castor beans. Tetraploid castor bean lines we created provide new resources for castor bean breeding system. And importantly, these findings enhance our comprehension of the molecular mechanisms underlying seed yield traits, thereby aiding the genetic enhancement of desirable seed traits in castor beans.</div></div>","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"228 ","pages":"Article 120937"},"PeriodicalIF":5.6,"publicationDate":"2025-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143726060","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we analyzed the differences in climatic conditions and soil physicochemical properties among six <em>T. grandis</em> planting sites across different regions. High-throughput sequencing was employed to analyze fungal community composition and co-occurrence network characteristics in healthy and diseased soils. Results indicated that root rot incidence was not significantly correlated with temperature, precipitation, or elevation. Compared to healthy soils, diseased soils exhibited lower organic matter, total nitrogen, and total potassium contents.

No significant difference was observed in the relative abundance of <em>Fusarium</em> between healthy and diseased soils. In diseased soils, the abundance of <em>Exophiala</em> and <em>Gibellulopsis</em> was positively correlated with <em>Fusarium</em> abundance.

The purpose of this study was to clarify the important effects of AMF on the medicinal components and cultivation yield of <em>C. pilosula</em> by investigating the AMF diversity in wild <em>C. pilosula</em> and carry out inoculation tests using AMF and plant growth-promoting rhizobacteria (PGPR) in the laboratory.

Fifteen genera were detected using high-throughput sequencing, confirming that <em>Glomus</em> was the dominant genus. The <em>Glomus</em> species represented the biotic factors, while available phosphorus and urease were the abiotic factors that most affected the medicinal effectiveness of “Pingshun ludangshen”.

Adsorbents were characterized by analytical (ASTM standards), instrumental (microscopy, spectroscopy, BET, X-ray diffraction), and computational methods.

The discarded CF residues (CFR) cause environmental pollution and wastage of resources. Converting CFR into functional carbon dots (CDs) is an important strategy to achieve its “waste-to-wealth” goal. Here, a CFR-derived CDs (CFR-CDs) based fluorescent sensor was successfully developed for the rapid and selective detection of mercury (Ⅱ) ions in aqueous environments, and its sensing mechanism for detecting Hg²⁺ was elucidated. First, the CFR was used as a precursor to extract fluorescent CDs via a simple and green hydrothermal method. The prepared CFR-CDs possessed a typical graphite-like structure with an average size of 2.23 nm, and exhibited good hydrophilicity, excellent photostability, and excitation-dependence fluorescence behavior, while emitting blue fluorescence. Interestingly, the CFR-CDs were highly selective towards Hg²⁺, and their fluorescence was rapidly quenched by Hg²⁺ (within 1 min). The prepared CFR-CDs were then used as a fluorescent sensor for efficient detection of Hg²⁺ in the range of 0.3–10 μmol/L with a low limit of detection (LOD) of 0.129 μmol/L. The recovery of the Hg²⁺ in actual water environments ranged between 98.60 % and 104.00 % with a relative standard deviation &lt; 5.0 %, demonstrating the reliability of the developed sensor. Additionally, the detection mechanism was revealed to be the synergistic action of the static quenching effect (SQE), inner filter effect (IFE) and photo-induced electron transfer (PET), generating CFR-CDs/Hg²⁺ complexes through the formation of surface chemical bonds and promoting the rapid shutdown of the sensor signal. This study demonstrates, for the first time, the application of CFR towards producing green and low-cost CDs as promising fluorescent sensor for the detection of Hg²⁺ in actual environmental samples, and is therefore helpful for improving the utilization efficiency of CFR and promoting the realization of carbon peak and carbon neutrality goals.</div></div>","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"228 ","pages":"Article 120914"},"PeriodicalIF":5.6,"publicationDate":"2025-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143726324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
