【摘要】 利用聚丙烯酰胺凝胶垂直板电泳方法,研究了小麦种子采用不同浓度的Ce(ON)3处理前后,用污水处理厂处理前后污水浇灌下生长出的小麦幼苗叶的过氧化物酶(POD)酶谱的变化.结果表明,污水中的重金属离子胁迫能促进POD的表达,而稀土元素对重金属离子有拮抗作用,使小麦幼苗叶的POD同工酶酶带发生变化.更多还原

【Abstract】 There researches the POD isoenzyme pattern changes of wheat seeding under the different dispose,using PAGE analysis.The results showed that the POD isoenzyme translation would be promoted by the forcing of heavy metal element in the waste water On the contrary,there are opposite effect between the rare earth element and heavy metal ion.And the rare earth element could change the POD isoenzyme patters.更多还原
