【摘要】 在高粱同核异质雌性不育系（3197A、T×398A）和异核异质雌性不育系（FA）、保持系的花药及雌蕊不同发育时期,共检测出13种正、负极向过氧化物酶同工酶。两种同核异质雄性不育系的过氧化物酶谱型非常接近,因此,这种酶可能是该基因编码的。 在3197A、T×398A中检测出2条专一性酶带（A₈、A₉）,这两条输带可能是同核异质雄性不育系的标志酶带。所有三套雄性不育系花粉粒中的过氧化物酶同工酶匀多于保持系,这可能是雄性不育细胞质基因对核基因表达的调控作用所造成。细胞质基因与细胞核基因存在着一定的相互关系,雄性不育特性可能是这两种基因共同作用的结果。更多还原

【Abstract】 The peroxidase isozymes have been analyzed with stamen and pistil from isonuclearalloplasmic （3197A, T×398A） and allonuclear alloplasmic（FA） male-sterile line, main-tainer line in Sorghum vulgare.The results showed that 13 kinds of Anode and Cathodeperoxidase isozyme have been examined at the different developmental stages of stamenand pistil.The isozymes patterns of peroxidase are very close in two isonuclear alloplasmic male-sterile line. The authors suggested that peroxidase isozyme might be coded by nucleargenes. 2 special bands, A₈, A₉, have been found in 3197A, T×398A. They may be a markbands of isonuclear alloplasmic male-sterile line. In the all three male-sterile line, theperoxidase isozyme of the stamen of male-sterile line are more than that of maintainerline at various stages of pollen grain development.This may be the result that male-ste-rile cytoplasmic gene regulated nuclear gene expressed. From these results, it is proposed that the cytoplasm acts as a element to regulatethe function of nuclear genes in the stamen developing process. There is a relationshipbetween the nuclear genes and cytoplasmic genes. The reason which the male-sterilecharacter to be caused is the action of the nuclear genes and cytoplasmic genes.更多还原
