| 摘 要： | 以玉米抗、感大斑病菌近等基因系为材料,研究了玉米抗病系和感病系在接种玉米大斑病菌后SOD活性和SOD同工酶谱的动态变化。结果发现,在病原菌侵染初期携带显性抗病单基因的抗病系SOD活性一般呈下降趋势,明显地低于不携带任何已知抗病基因的感病近等基因系;在病原菌侵染中、后期却较大幅度上升,反而逐渐明显地高于感病近等基因系。在HZ1遗传背景中Rf值为0.25的SOD同工酶酶带,与Ht2和HtN等抗病基因的作用有关。本文认为SOD及有关活性氧代谢在玉米对大斑病菌抗性中可能具有重要的作用。

| Abstract: | Dynamic changes in activities and electrophoretograms of superoxide dismutases (SOD) during infection by Exserohilum turcicum were analysed in two sets of maize near-isogenic lines, each com posed of a susceptible recurrent parent (HZ1 or B37) and three resistant backcross-derived lines with one of Ht1、Ht2 and HtN genes for resistance to the pathogen. |
