1·Phytotoxin, one of the most important factors of fungal disease which is the major plant disease, is paid much attention to.
植物真菌病害是植物的主要病害，毒素作为引发病害的重要因子之一而受到广泛的注意。
2·Those above results indicated that pine wood nematode promoted the production of phytotoxin by bacterium in the host tissue.
该结果说明松材线虫在寄主组织中能促进细菌的产毒。
3·Results also showed that pine wood nematode itself neither produced phytotoxin nor affected the toxicity of extracts from the culture of bacterium after the addition of it.
实验结果表明松材线虫本身不产生毒素，在荧光假单胞菌培养液的无细胞滤液中加入无菌松材线虫未能显著改变其毒性。
