Abstract：
Chitin is composed of N-acetylglucosamine units. Chitin a polysaccharide found in the cell walls of fungi and exoskeletons of insects and crustaceans, can elicit a potent defense response in plants. Through the activation of defense genes, stimulation of defensive compound production, and reinforcement of physical barriers, chitin enhances the plant\'s ability to defend against pathogens. Chitin-based treatments have shown efficacy against various plant diseases caused by fungal, bacterial, viral, and nematode pathogens, and have been integrated into sustainable agricultural practices. Furthermore, chitin treatments have demonstrated additional benefits, such as promoting plant growth and improving tolerance to abiotic stresses. Further research is necessary to optimize treatment parameters, explore chitin derivatives, and conduct long-term field studies. Continued efforts in these areas will contribute to the development of innovative and sustainable strategies for disease management in agriculture, ultimately leading to improved crop productivity and reduced reliance on chemical pesticides.
摘要：
几丁质由N-乙酰葡糖胺单元组成。几丁质是一种在真菌的细胞壁和昆虫和甲壳类动物的外骨骼中发现的多糖，可以在植物中引起有效的防御反应。通过激活防御基因,防御性化合物生产的刺激，加强物理障碍，几丁质增强植物抵御病原体的能力。基于几丁质的治疗已显示出对真菌引起的各种植物病害的功效，细菌,病毒，和线虫病原体，并已融入可持续农业实践。此外，几丁质治疗已经证明了额外的好处，例如促进植物生长和提高对非生物胁迫的耐受性。需要进一步的研究来优化处理参数，探索几丁质衍生物，并进行长期的实地研究。这些领域的持续努力将有助于制定创新和可持续的农业疾病管理战略,最终导致提高作物生产力和减少对化学农药的依赖。
