根结线虫与寄主植物互作机理的研究进展

根结属(Meloidogyne Gǒldi)线虫必须寄生于寄主植物根系并获取所需的全部营养，才能完成其完整的生活史。此种寄生行为会对植物造成一定的伤害，而寄主植物的反应也会对根结线虫产生显著的影响，从而引发线虫的种种高度专化性适应。寄生过程引起的根结线虫与寄主植物之间的一系列互作反应，包括根结线虫对寄主植物的致病现象，寄主植物的感病反应和抗病反应。根结线虫与寄主的关系是在长期进化过程中形成的。

Advancesin Studieson Interaction Mechanism Between Root-knot Nematodes and Host Plants

Root-knot nematodes (Meloidogynespp.) take in adequate nutrition and complete a life cycle by parasitizing the root system of host plants. The host plants will be damaged when infected by root-knot nematodes. The response of the host plants parasitized can also produce evident impact to the root-knot nematode, resulting in adaptation of the nematodes specific to different host plants. A series of interactions such as nematode pathogenicity, host susceptibility and host resistance could form due to parasitism. The relationship between the hosts and the root-knot nematodes is formed in the course of long-term evolution.
