摘　要：摘　要：松材线虫病(pine wilt disease， PWD) 是一种重大的森林病害，对我国乃至世界生态环境和森林资源造成了严重破坏和威胁。由于该病发生发展的复杂性，病原的致病机理一直不清楚。面对松材线虫的侵染，寄主松树势必要启动防御机制予以抵抗。现对寄主松树受松材线虫侵染后组织病理学、生理生化及分子病理学的变化进行综述，并对今后从寄主角度研究松材线虫病提出思考和展望，这将有助于进一步了解松树与松材线虫的互作过程，并揭示寄主从防御到最后死亡的内在原因，从而找到防治松材线虫病的有效策略。

Abstract: Abstract: The pine wood nematode (PWN) Bursaphelenchus xylophilus is notorious for causing the pine wilt disease (PWD)， which is one of the most serious coniferous forests diseases and has made a threat to ecological environment and forest resources worldwide. The mechanism of pathogenesis has remained unclear due to the complexity of the disease. To resist the infection of B. xylophilus， the host would launch a defense. In this paper， the changes of histopathology， physiology and biochemistry and molecular pathology in pine were summarized， when it was infected by B. xylophilus， and we put forward some thoughts and prospects about the PWD from the point of host， which will provide an insights to help us more deeply understand the interaction process and reveal the reason of defense and death in the host to search the control strategy.
