摘要: 本文分析了家鼠属(Rattus)4种鼠和姬鼠属(Apodemus)2种鼠的苹果酸脱氢酶、血浆中B1区和B2区蛋白质、血浆请蛋白、前清蛋白以及红细胞中血红蛋白的变异。结果表明,MDH在进化上是比较保守的,其中MDHM和MDHS2带在各鼠间位于同一泳动线上,仅MDHS1带的泳动速度出现属间和种间的微小差异;血浆中B1区和B2区的蛋白质带、清蛋白带以及前清蛋白带各鼠间出现明显的差异,表现为黑线姬鼠和社鼠在B1区出现2种多态型区带,褐家鼠在B2区也有2种多态型带;各鼠间的血红蛋白变异比较明显,主要表现在区带数和主成分的泳动度显著不同,而且社鼠的Hb 出现3中多态型,黄毛鼠出现2种多态型,其与各鼠的Hb 皆为单态性。上述16项生化特性按相似和相异进行配对比较,初步表明黄毛鼠与褐家鼠亲缘上比较相近,白腹巨鼠要比其他3种鼠亲缘上更接近于黑线姬鼠,而社鼠与白腹巨鼠之间进化分歧相对的较大。

Abstract: The MDH isozymes , hemoglobins and some plasma proteins of 4 species of the Rattus genus and 2species of the Apodemus genus were analysed by means of the vertical slab gel elect rophoresis . The results obtained showed that the MDH isozymes were rather conservative in evolueion . The MDHM and MDHS2 zones among all species analysed were respectively located to the same migratory line , but migratory speed of the MDHS1 zones were different between the species of the two genus . The variations of migratory speed on the zones of albumin , pre –allbumin , the proteins in B1and B2 regions among the species were found . There were 2 polymorphic types in the B1 region of A . agrarius and R . niviventer , respectively . There were also 2 polymorphic types in the B2 region of R . norvegicus .It was also found to the variations of the migratory speed and the number of Hb zones among all species analysed . There were 2Hb polymorphic types for R. rattoid and 3 for R. niviventer . The phonetic analysis with 16 biochemical characters by the pair-group method showed that R . norvegicus was closed to R . rattoides in ally. The R . edwardsi was closer to A . agrarius than the res 3 species of the Rattus in ally . There were relatively marked divergence between R. edwardsi and R . niviventer in evolution .
