水稻稻瘟病菌(Pyricularia oryzae)的菌丝悬浮液和孢子萌发液等无菌处理制备的粗毒素对水稻均有毒性已被国内外研究所证实,并利用粗毒素从感病的稻株中筛选出抗病突变体。明确了以粗毒素代替病原菌作为抗性选择压力的可能。但是,稻瘟病菌是由一系列致病力强弱不同的菌系组成的群
The mycotoxin of Pyricularia oryzae mycelial suspension and spore germination liquid and other sterile treatment of crude toxins have toxicity to rice has been confirmed by the domestic and foreign research, and the use of crude toxins from susceptible rice plants screening Outbreak-resistant mutants. Clear the possibility of using crude toxin instead of pathogenic bacteria as a stress-selective pressure. However, Magnaporthe grisea is a group of bacterial strains that differ in their virulence
