粳稻３４１Ａ、３４１Ｂ的不同器官和花药及雌蕊的不同发育时期共检测出９种ＰＯＤ同工酶谱带，其中ＰＯＤ＿５、ＰＯＤ＿６在所有１０个器官中存在，因此可以认为是粳稻３４１Ａ、３４１Ｂ的基本谱带。ＰＯＤ＿８、ＰＯＤ＿９谱带仅在少数器官中存在，具有一定的器官专一性。花粉粒发育的两个关键时刻，ＰＯＤ同工酶均多于保持系，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致，细胞质基因与细胞核基因存在着一定的相互关系，雄性不育可能是这两种基因共同作用的结果。
Nine POD isoenzyme bands were detected in different organs, anthers and pistil of japonica rice 341A and 341B. POD_5 and POD_6 were found in all 10 organs and could be considered as the basic spectrum of japonica rice 341A and 341B band. POD_8, POD_9 bands exist only in a few organs, with a certain organ specificity. The pollen grains developed at two critical juncture with more POD isoenzymes than the maintainer lines, which may be due to the regulatory effect of male sterility cytoplasm on nuclear gene expression. The cytoplasmic and nucleus genes are related to each other. Male Sterility may be the result of both genes acting together.
