Endolichenic fungi represent an important ecological group of microorganisms that form associations with photobionts in the lichen thallus. These endofungi live and coevolve lichens are known for synthesizing secondary metabolites novel structures diverse chemical skeletons making them unexplored microbial community great interest. As part our search new phytoprotectants, this work, we studied endolichenic fungus Xylaria sp. isolated from Hypogymnia tubulosa, which grows as epiphyte on bark endemic Canarian tree Pinus canariensis. From extract liquid fermentation, two unreported piliformic derivatives, (+)-9-hydroxypiliformic acid (1) (+)-8-hydroxypiliformic (2), along four previously reported compounds, (+)-piliformic (3), hexylaconitic A anhydride (4), 2-hydroxyphenylacetic (5), 4-hydroxyphenylacetic (6). Their were elucidated based NMR HRESIMS data. The compounds tested their insect antifeedant (Myzus persicae, Rhopalosiphum padi, Spodoptera littoralis), antifungal (Alternaria alternata, Botrytis cinerea, Fusarium oxysporum), nematicidal (Meloidogyne javanica), phytotoxic effects mono- dicotyledonous plant models (Lolium perenne Lactuca sativa). Compounds 4, 5, 6 effective antifeedants against M. persicae 4 was also active R. padi. Moreover, 3 showed activity B. cinerea only nematicidal. had a strong effect L. sativa growth, 3, 5 identified agents, while at low concentrations stimulated root growth.

Significant postharvest losses and food safety issues persist in many developing nations, primarily due to fungal activities, including mycotoxin production. In this study, green synthesised zinc oxide nanoparticles (ZnO-NPs) were prepared from leaf extracts of Syzygium cordatum (ZnO 1), Lippia javanica 2), Bidens pilosa 3), Ximenia caffra 4). Physicochemical characteristics the ZnO-NPs determined using X-ray diffraction (XRD), Fourier transmission Infrared spectroscopy ultraviolet–visible (UV–vis) spectroscopy, scanning electron microscopy (SEM), (TEM). The XRD analysis confirmed presence a wurtzite crystal structure hexagonal shape ZnO (NPs), with an average size ranging between 25 43 nm. microscopic examination morphology revealed spherical particles sizes 37 47 nm diameter. antifungal efficacy was assessed against pathogenic plant fungi, Botrytis sp.

A significant interaction type species observed, highest susceptibility Mucor 2, achieving over 50% inhibition. also showed high all ZnO-NPs. Molecular docking results strong H-bonding interactions receptors sp., P. exhibited least susceptibility. tests that 2 inhibitory effect on low minimum concentration (MIC) µg/mL, attributed its larger positive zeta potential. This study indicates NPs, particularly those mediated have promising potential as effective agents, which could play role reducing decay losses.

The growing concerns over food safety have intensified calls for alternatives to toxic pesticides in agriculture. Despite these concerns, the global agricultural industry remains heavily reliant on chemical maintain crop yields. However, overuse of chemicals has resulted significant biodiversity loss and environmental degradation, highlighting urgent need safer, non-toxic, sustainable alternatives. Trichloroisocyanuric acid (TCCA), a cost-effective relatively safe industrial oxidant commonly used disinfection, shown potential plant disease management. its application this context largely unexplored. In study, we evaluate efficacy TCCA controlling Pseudomonas syringae pv. actinidiae (Psa), causative agent bacterial canker kiwifruit, explore underlying mechanisms action. Our results demonstrate that effectively inhibits Psa growth vitro, even at low concentrations, with minimum inhibitory concentrations (MICs) 20 mg/L (TCCA added directly suspension) 100 (Psa cells mixed liquid LB medium before adding TCC). vivo, treatment concentration 500 substantially reduced colonization both kiwifruit leaves canes, outperforming conventional bactericides such as copper hydroxide, chlorothalonil, ethylicin, well alternative treatments like pyraclostrobin-dysonline Xinjunan acetate. Mechanistic investigations revealed inhibited biofilm formation, impaired motility, disrupted cell integrity, suppressed expression virulence-related genes, ultimately leading death. Additionally, healthy infected canes induced activity key defense-related enzymes, including catalase (CAT), peroxidase (POD), glutathione reductase (GR), phenylalanine ammonia-lyase (PAL), suggesting may activate systemic defense responses. These findings position promising, environmentally friendly traditional bactericides, offering effective solution management ecological risks.
