抗植保素基因Bx-cathepsin W提高松材线虫在马尾松内存活率

通过鉴定松材线虫抗植保素基因Bx-cathepsin W功能，发现该基因提高松材线虫在马尾松内存活率。马尾松分泌植保素杀松材线虫，阻止松材线虫入侵。松材线虫通过抗植保素基因Bx-cathepsin W等基因抵抗寄主植保素的杀伤。表明抗植保素基因Bx-cathepsin W有保护松材线虫的作用，若将该基因沉默可达到防治松材线虫的目的。

Through functional characterization of the phytoalexin resistance gene Bx-cathepsin W in Bursaphelenchus xylophilus (pine wood nematode, PWN), we determined that this gene increases the survival rate of the nematode within Pinus massoniana (Masson pine). Pinus massoniana secretes phytoalexins to kill B. xylophilus and prevent its invasion of the host. Bursaphelenchus xylophilus counteracts the lethal effects of host phytoalexins via multiple genes including Bx-cathepsin W. These findings demonstrate that the phytoalexin resistance gene Bx-cathepsin W plays a protective role for pine wood nematodes, and silencing this gene can provide a viable strategy for controlling pine wilt disease caused by B. xylophilus.
