在小麦条锈菌黄色和白色夏孢子菌系混合繁殖的群体中,筛选出一新的白化菌系。新菌系在鉴别寄主上的反应型明显不同于两原始菌系,其夏孢子芽管的多核率较原始菌系高,这些结果表明该新菌系是经异核作用产生的。本研究还发现,新苗系的多核率随继代转接而下降,但其毒性不变。 A new albino bacterial strain was screened from a mixed population of wheat stripe rust yellow and white. The new type of bacteria in the identification of the host response was significantly different from the two original bacteria, the spores of the summer spores germ tube than the original high nuclear strains, these results show that the new strain is produced by heterokaryon effect. The study also found that the new plantlet nuclear rate of nuclear transfer with the decline, but its toxicity remains unchanged.
