榨菜胞质雄性不育系及其保持系的个体发育过程中过氧化物酶 (POD)和酯酶 (EST)同工酶的表达均具有特异性。榨菜不育系的POD在营养生长期的酶谱与保持系相同 ,但在生殖生长期花蕾中的酶活性显著高于保持系 ,其酶谱中出现两条在保持系中不表达、迁移率分别为 0 .12和0 19的特异带。榨菜的EST同工酶表达丰富 ,特异性强 ,不育系的EST同工酶在营养生长期与保持系有所不同 ,在生殖生长期差异显著 ,活性显著低于保持系 ,且花蕾的酶谱中缺少在保持系中表达的迁移率分别为 0 .38和 0 .4 0的两条特异谱带。
The expression of peroxidase (POD) and esterase (EST) isoenzymes in tuberous cytoplasmic male sterile lines and their maintainer lines during the developmental process is specific. The POD of tuber mustard was the same as the maintainer of POD in vegetative growth stage, but the enzyme activity in flower buds of reproductive growth stage was significantly higher than that of maintainer line, and two of the enzyme lines showed no expression in the maintainer line. The migration rate Specific bands of 0,12 and 0 19, respectively. The expression of EST isoenzyme in tuber mustard is rich and specific. EST isoenzyme of CMS is different in vegetative stage and maintainer stage, and has significant difference in reproductive stage and activity significantly lower than maintainer line, The spectrum lacks two specific bands with mobilities of .38 and .04, respectively, expressed in the maintainer line.
