While chemical pesticides remain the primary control measure, their use poses significant risks to human health and the environment. Consequently, there is a growing demand to explore eco-friendly and sustainable alternatives to chemical control methods. In this study, <em>Bacillus velezensis</em> HC-10 was isolated from honeysuckle leaves and exhibited a notable inhibition rate of 66.74 % against <em>A. alternata</em> in plate assays. The volatile organic compounds (VOCs) produced by HC-10 demonstrated significant inhibitory effects on mycelial growth and spore germination of <em>A. alternata</em>. A greenhouse pot experiment validated the effectiveness of VOCs in disease control, with efficacy reaching 74.84 % after 21 days. Using HS-SPME-GC-MS, twenty VOCs were identified, of which six were evaluated for their antifungal activity against <em>A. alternata</em>. Isovaleric acid showed the most potent antifungal activity, with the lowest EC₅₀ value of 2.22 μL. The antifungal mechanism of isovaleric acid was investigated through morphological and physiological analyses. Isovaleric acid compromised the integrity of the cell wall and membrane of <em>A. alternata</em>, disrupted mitochondrial function, hindered energy metabolism, and diminished antioxidant capacity. Additionally, <em>in vivo</em> experiments revealed that isovaleric acid effectively controlled leaf spot disease, achieving a maximum control efficacy of 77.27 % at an 800-fold dilution. Overall, this study highlights the potential of <em>B. velezensis</em> HC-10 and its VOCs as promising biocontrol agents for managing honeysuckle leaf spot disease.</div></div>","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"231 ","pages":"Article 121190"},"PeriodicalIF":5.6,"publicationDate":"2025-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143946946","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}

However, the underlying regulatory mechanisms of how different Lei bamboo cultivars adapt to the environment is currently unclear. This study explores the differences in growth phenotypes, physiological traits, transcriptomic profiles, and rhizosphere microbial communities of four Lei bamboo cultivars. Significant physiological differences were observed in leaf soluble sugar, total nitrogen content, bamboo shoot soluble protein, and free amino acid levels among the cultivars. Transcriptomic analysis identified differentially expressed genes (DEGs) involved in key metabolic pathways, such as glycolysis, gluconeogenesis, and starch/sucrose metabolism, which regulate carbohydrate metabolism in Lei bamboo. Rhizosphere microbial communities showed distinct bacterial and fungal structures and functional differences, with Anhui Lei bamboo exhibiting higher fungal richness and diversity. The interaction between Trichoderma and plant glycolysis and energy metabolism genes <em>FBA</em> and <em>PDCA</em> may enhance nitrogen absorption and assimilation in the plant leaves. Additionally, the accumulation of free amino acids in bamboo shoots could be regulated by gene expression driven by the <em>WRKY70</em> transcription factor, as well as by the influence of Chaetomium. This study not only provides deeper insights into plant-microbe interaction mechanisms but also establishes a comprehensive regulatory framework that integrates genetics, physiology, and microbiology for Lei bamboo.

Silicon (Si) can mitigate heavy metal toxicity in plants. <em>Juglans sigillata</em> (<em>J. sigillata</em>) is highly nutritious and economically valuable for its wood; however, Cd strongly inhibits its growth. To investigate the beneficial effects of Si in alleviating Cd stress, four treatment groups were established: CK (H₂O only), Si (Si only), Cd (Cd only), and CdSi (Cd and Si). The results showed that Cd accumulation in the roots, stems, and leaves decreased by 9 %, 46.1 %, and 41.6 %, respectively, in the CdSi treatment group compared to the Cd-only group, thereby reducing plant damage. Compared to Cd treatment alone, the CdSi group exhibited significant increases in the activities of superoxide dismutase, peroxidase, and catalase by 50.64 %, 118.35 %, and 9.83 %, respectively, along with an increase in proline content.

A split-root pot experiments were done in 2020 and 2021, and both direct (2020) and residual (2021) effects of biochar were investigated. The experimental design included three factors: biochar addition (without biochar (NBC), wheat stover biochar (WSB), and softwood biochar (WB)), and irrigation mode (adequate irrigation (AI), traditional deficit irrigation (TDI), and APRI), and salinity level (0 and 200 mM sodium chloride). The results indicated that salinity and reduced irrigation reduced gas exchange rates, stomatal size, leaf water potential and seed cotton yield, but increased leaf ABA concentration and intrinsic water use efficiency (WUE_n). In both years, biochar application attenuated the adverse effects of salinity stress and improved the physiological characteristics of cotton plants, though in 2021 biochar reduced stomatal size, stomatal density, leaf ABA concentration, maximum stomatal conductance, seed cotton yield, WUE_n, and yield-level water use efficiency (WUE_s) compared to 2020. APRI coupled with WSB resulted in the highest WUE_s in both years. Structural equation model analysis indicated that leaf water potential and ABA indirectly affected WUE_n and WUE_s by altering stomatal traits. Stomatal conductance had a negative direct effect on WUE_n, whereas stomatal density had a positive direct effect on WUE_s. Considering the direct and residual effects of biochar, the APRI coupled with WSB is a promising strategy for increasing WUE and alleviating salinity stress in cotton plants.</div></div>","PeriodicalId":13581,"journal":{"name":"Industrial Crops and Products","volume":"231 ","pages":"Article 121206"},"PeriodicalIF":5.6,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143947156","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}

In this study, native-like lignins were isolated and thoroughly analyzed using a variety of analytical techniques, including gel permeation chromatography (GPC), analytical pyrolysis coupled to gas chromatography/mass spectrometry (Py-GC/MS), two-dimensional Nuclear Magnetic Resonance (2D NMR), and ³¹P NMR. The data revealed significant differences in the lignin composition of the two species.

In contrast, tagasaste lignin exhibited a slight predominance of S units (H:G:S ratio of 2:46:52; S/G 1.13). These compositional variations significantly influenced the distribution of the different lignin interunit linkages. Hence, leucaena lignin was characterized by fewer of β–<em>O</em>–4′ alkyl-aryl ether linkages (66 % of all linkages) and a higher proportion of condensed linkages, making it more resistant to delignification. In contrast, tagasaste lignin presented higher levels of β–<em>O</em>–4′ alkyl-aryl ether linkages (74 %) and fewer condensed linkages, rendering it more susceptible to delignification.

Two genotypes were firstly subjected to CS (8/4°C) for 25 days and FS (2/-3°C) for 3 days and then recovered from cold stress (30/25°C) for 15 days.

Dr5 not only maintained higher these antioxidant enzyme activities and contents of AsA and GSH, but also had higher the AsA/DHA and GSH/GSSG ratios compared with Dr17 under CS and FS, indicating better cellular redox state in Dr5. In addition, Dr5 improved the accumulation of sucrose for osmotic adjustment and osmoprotectant, whereas Dr17 enhanced fructose and glucose metabolisms for energy supply and reactive oxygen species scavenging under CS and FS.
