线虫表被层在寄主-寄生者互作中起着多种关键作用。几种凝集素在不同虫龄的表被层中的结合能力测定证明,麦胚凝集素(WGA)仅结合到3龄繁殖幼虫及卵壳表面,但这种结合经常发生在毒性松材线虫分离物中,而不是低毒松材线虫分离物的表被层。卵壳表面WGA的结合最强。WGA经常结合到线虫表被层上。表被层蛋白提取物的分析显示其碳氢化合物及蛋白质谱随线虫发育和对松树寄主的入侵而变化。研究结果表明,松材线虫的表被层蛋白在松树寄主和线虫间的互作中起着重要作用。
The nematode watchtowers play a number of key roles in host-parasitoid interactions. The binding ability of several lectins in the epidermis of different age of insects proved that wheat germ agglutinin (WGA) only binds to the 3rd instar larvae and the surface of eggshell, but this combination often occurs in the separation of virulent Rather than the low-toxic pine nematode isolates. The combination of egg shell surface WGA the strongest. WGA is often incorporated into the nematode table layer. Analysis of epidermal protein extracts revealed that their hydrocarbon and protein profiles varied with nematode development and invasion of the pine host. The results show that the epidermal layer protein of pine wood nematode plays an important role in the interaction between the host and the nematode pine tree.
