壳聚糖对植物病原体的作用机制及其影响因素
Chitosan: The Action Mechanism on Plant Pathogens and Its Influencing Factors
壳聚糖具有优良的抗菌活性以及天然无毒、生物相容性良好、可生物降解和可再生、来源广泛的特性。为充分理解壳聚糖对植物病原体的作用,本文归纳了壳聚糖对植物病原体的4种作用机制：电荷作用、沉积作用、螯合作用和诱导作用,分析了影响壳聚糖对植物病原体作用效果的主要因素：病原体、壳聚糖、使用条件及其他方面。同时,指出了目前壳聚糖对植物病原体作用研究领域的问题：研究方法多样、研究结果间存在差异甚至出现截然相反结论。建议通过采用先进的仪器设备、建立三维生物细胞模型以及采用统一研究方法或制定研究标准等措施来强化壳聚糖对植物病原体作用的研究,以期为开发以壳聚糖为活性成分的新型植物病害防治剂提供理论指导。
Chitosan has excellent antibacterial activity and natural non-toxicity, good biocompatibility, biodegradability and renewability, and extensive raw material sources. In order to fully understand the effect of chitosan on plant pathogens, this paper summarized four kinds of action modes of chitosan on plant pathogens, namely charge effect, sedimentation, chelation and induction, analyzed the main factors affecting the bacteriostatic effects of chitosan on plant pathogen, including pathogen, chitosan, using conditions and the others. Meanwhile, it pointed out some problems in the research field: various methods, different results, and even opposite conclusion of the research on chitosan acting on plant pathogen at present. Adopting advanced equipment, establishing three-dimensional biological cell model and adopting unified research method or developing research standard were suggested to improve the study of chitosan acting on plant pathogen, so as to provide a theoretical basis for the development of novel plant disease control agent with chitosan as the active ingredient.
