| 摘 要： | 壳聚糖是一种天然的高分子聚合物,在农业上控制植物病害方面具有重要作用。壳聚糖及其衍生物对细菌、真菌、病毒及其他病虫害具有高效的杀菌和抑菌作用,可以诱导植物细胞发生一系列的抗性反应,包括植保素、病原相关(pathogen-related)蛋白、蛋白酶抑制剂、木质素及胼胝质的合成和聚集,壳聚糖作为植物抗性反应的激发子,启动植物的防御系统,有效地增强植物的抗病性。通过对壳聚糖及其衍生物在植病互作中的作用机制进行研究,从而将壳聚糖更广泛地应用于农业的各个方面。

| Abstract: | Chitosan,an important natural biopolymer that have potential in agriculture with regard to controlling plant diseases.Chitosan and its derivates were reported to be active against bacterials,fungals,viruses and other pests.They can induce the host defense responses include phytoalexins,pathogen-related(PR) proteins and proteinase inhibitors,lignin synthesis,and callose formation.As a general elicitor,chitosan also trigger host resistance,systemic immuntity and help strengthen plant self-defense.To a further... |
