| 摘 要： | 在玉米黄早4雄性不育系、保持系的10个组织(叶、根、茎、芽鞘、胚轴、苞叶、穗轴、花丝、雌蕊、花药)中共检测出18种正、负极向过氧化物酶,其中有7个组织不育系与保持系间过氧化物酶没有差异,只有在3个组织中(叶、茎、花药)不育系与保持系间的过氧化物酶存在差异,说明玉米黄早4雄性不育系及保持系的过氧化物酶可能由细胞核基因编码。不育系与保持系个别组织内过氧化物酶存在差异,可能是由于核内编码过氧化物酶的基因表达异常所引起,而这种表达异常,可能是与不育系中不育细胞质基因调控核基因的表达有关。

| Abstract: | 18 anode and cathode peroxidase isozy-mes have been examined in Huang Zao No.4 male-sterile line and maintainer (Zeamays).There are difference in the peroxidaseisozymes of leaf,stem,anther between male-sterile line and maintainer,but no differencehave been examined on peroxidase of radicle,coleoptile,mesocotyl,filament,floral leaf,ovary,panicle axis in male-sterile line andmaintanier. According to the results,the authorssuppose that the peroxidase may be codedby nuclear gene,and the difference in theperoxidase isozymes might be caused by theeffect of cytoplasmic male-sterile gene on nu-clear genome. |
