Using a pair of degenerate primers based on the conservative region, hmg - box, of human sry gene, tow different fragments of sox gene, essox3 and essox22 were amplified from female and male eriocheir sinensis, the sequence results indicated that essox3 and essox22 shown high homology to human sox genes, and the identities to human sox genes in dna sequence and amino acid sequence are 84 % 、 85 % and 97 % 、 81 %, respectively. it might be concluded that sox gene was highly conservative in phylogenesis
二、研究論文1 、參照人sry基因hmg - box保守區的序列，設計一對兼并引物， pcr擴增了中華絨螯
蟹的sox基因，並對擴增產物進行了克隆和測序。結果在
雌雄個體中篩選出兩個不同的sox基因essox3和essox22 ，其dna序列和編碼的氨基酸序列與人相應sox基因的相似性分別為84 % 、 85 %和97 % 、 81 % ，顯示該基因在進化上具高度的保守性。
The crabs were dissected respectively after one week of treatment, and the ovaries were kept in 70 % ethanol with 50mmol / l edta
