本研究在亚致死浓度的选择压力下,分别用玉米大、小斑菌毒素筛选玉米单倍体胚性细胞无性系,获得了抗性细胞团。然后用毒素及病菌孢子处理,初步阐明了抗病性与过氧化物酶活性的关系,为玉米单倍体愈伤组织抗病性鉴定提供了生化依据。 In this study, under the selective sublethal concentration, the maize haploid toxin was used to screen maize haploid embryogenic cell clones, and the resistant cell mass was obtained. Then with the toxin and bacteria spores treatment, initially clarified the relationship between disease resistance and peroxidase activity, providing a biochemical basis for the identification of the disease resistance of maize haploid callus.
