| 摘 要： | 用水平淀粉电泳技术 ,对兴凯湖翘嘴红鱼白的肌、肝、眼、心 4种不同组织的 8种同工酶 (LDH、EST、MDH、IDH、SOD、ME、G - 6-PDH、ADH)进行了研究。分析了各种同工酶的基因表达谱式。其中 ,在所检测到的 2 0个基因座位中只有EST同工酶中的一个座位 (Est - 2 )表现为多态。兴凯湖翘嘴红鱼白的多态率 (P)为 0 0 50 0 ,平均杂合度 (H)为 0 0 139。与其它鲤科硬骨鱼类相比 ,兴凯湖翘嘴红鱼白在蛋白质水平上的遗传变异表现比较贫乏

| Abstract: | By means of horizontal starch gel electrophoresis,eight isozymes (LDH,EST,MDH,IDH,SOD,ME,G-6-PDH,ADH)in muscle,liver,eye,heart of Erythroculter ilishaeformis Bleeker were srudied,The genee expression patterns of evevy isozyme were analyzed.Amony 20 loci screened only I locus(Est-2)of EST was polymorphic.The percentage of polymorphic loci and average heterozygosity of Erythroculter ilishaeformis Bleeker in Xingkai Lake was 0 0500 and 0 0139 respectively.Compared with other bony fishes of Cyprinidae,The genetic variation of Erythroculter ilishaeformis Bleeker in Xingkai Lake at protein level is poor. |
