Advancements in polymer science and nanotechnology hold significant potential for addressing the increasing demands of food security, by enhancing shelf life, barrier properties, nutritional quality harvested fruits vegetables. In this context, biopolymer-based delivery systems present themselves as a promising strategy encapsulating bioactive compounds, improving their absorption, stability, functionality. This study provides an exploration synthesis, characterization, postharvest protection applications nanocarriers formed through complexation chitosan oligomers, carboxymethylcellulose, alginate 2:2:1 molar ratio. process was facilitated methacrylic anhydride sodium tripolyphosphate cross-linking agents. Characterization techniques employed include transmission electron microscopy, energy-dispersive X-ray spectroscopy, infrared thermal analysis, powder diffraction. The resulting hollow nanospheres, characterized monodisperse distribution mean diameter 114 nm, exhibited efficient encapsulation carvacrol, with loading capacity approximately 20%. Their suitability phytopathogen control assessed vitro against three phytopathogens—Botrytis cinerea, Penicillium expansum, Colletotrichum coccodes—revealing minimum inhibitory concentrations ranging from 23.3 to 31.3 μg·mL−1. indicates higher activity compared non-encapsulated conventional fungicides. ex situ tests tomato (cv. ‘Daniela’) protection, doses (50–100 μg·mL−1, depending on pathogen) were necessary achieve high protection. Nevertheless, these remained practical real-world applicability. advantages safety, coupled multi-target mode action, further enhance appeal nanocarriers.

Challenges and Opportunities Arising from Host–Botrytis cinerea Interactions to Outline Novel and Sustainable Control Strategies: The Key Role of RNA Interference

International Journal of Molecular Sciences, Journal Year: 2024, Volume and Issue: 25(12), P. 6798 - 6798

Published: June 20, 2024

The necrotrophic plant pathogenic fungus Botrytis cinerea (Pers., 1794), the causative agent of gray mold disease, causes significant losses in agricultural production. Control this fungal pathogen is quite difficult due to its wide host range and environmental persistence. Currently, management disease still mainly based on chemicals, which can have harmful effects not only environment human health but also because they favor development strains resistant fungicides. flexibility plasticity B. challenging defense mechanisms ability evolve strategies escape chemicals require new control for successful management. In review, some aspects host-pathogen interactions from novel sustainable could be developed (e.g., signaling pathways, molecules involved immune mechanisms, hormones, post-transcriptional gene silencing) were analyzed. New biotechnological tools use RNA interference (RNAi) are emerging crop protection scenario as versatile, sustainable, effective, environmentally friendly alternatives chemicals. RNAi-based fungicides expected approved soon, although will face several challenges before reaching market.
