Feng yongfeng : please release pikas for the sake of large grass plains
馮永鋒：為了大草原，請放過鼠兔吧！Extensive mitochondrial dna polymorphisms were found among lagurus lagurus, mus musculu ， rattus norvegicus and mice. the findings will help us to understand the dispersion and evolution of these animals
通過瓊脂糖凝膠電泳對這些片段進行測定，同時估算出草原兔尾鼠線粒體dna的長度約為16 . 6kb 。With a pair of degenerate primers designed according to the conserved region among the known cdna sequences of five rodents, a cdna fragment was generated by rt - pcr from total rna isolated from ovaries of lagurus lagurus
首先根據已發表的五種嚙齒目動物zp3cdna序列同源性分析結果設計特異性引物， rt - pcr擴增草原兔尾鼠zp3 （ lzp3 ） cdna保守序列。In this study, by combining rt - pcr and race, a full - length cdna encoding the lagurus lagurus zp3 ( lzp3 ) was isolated from the lagurus ' s ovary and cloned into a prokaryotic expression vector and a eukaryotic expression vector for further immunocontraceptive investigations
本論文研究工作採用rt - pcr與race相結合的方法，首次克隆了草原兔尾鼠zp3全長cdna並進行了序列分析，構建了真核表達質粒，為草原兔尾鼠免疫不育的研究奠定了基礎。According to measured data, testis sizes from animals captured in september 2000 were different remarkably from that in april and july 2001, and not differences among their age groups, which was indicated that l. lagurus in september 2000 did not have reproductive abilities. by use the same method, we have observed that l. lagurus in april 2001 and groups from - age and - age ( old ) in july 2001 have reproductive abilities. in addition, the reproductive ability from the - age group in july 2001 was intermediated between the groups in september 2000, - age group in april and - age group in july 2001
我們對不同時間參與繁殖的雄鼠睪丸大小的測定結果表明， 2000年9月雄鼠睪丸大小與2001年4月和7月的有顯著性差異，表明2000年9月草原兔尾鼠雄鼠進入繁殖休止期； 2001年4月種群中齡和齡雄鼠睪丸大小無顯著性差異，與2001年7月的相比有顯著性差異，但與2001年7月種群的齡鼠和齡鼠的相比無顯著性差異，表明2001年4月和2001年7月種群的齡和齡草原兔尾鼠雄鼠具繁殖能力； 2001年7月的齡雄鼠睪丸大小與2000年9月的有顯著性差異，表明該時期齡雄鼠的繁殖力介於2000年9月種群和2001年4月和7月種群的齡鼠和齡鼠之間。According to the live coefficient c, we modified the predictions for this age group and come to a conclusion that is corresponding to actual field data. in other words, the numbers of - age and - age were nearly zero with their densities below 4 / hm2. these results suggest that l. lagurus population began to decline
運用校正後的存活系數繼續預測，其結果與2001年9月的野外調查結果基本一致，證實當年草原兔尾鼠的數量非常少，低於4 . 0隻/公頃，且齡鼠和齡鼠幾乎為零。In addition, for construction of prototype dna vaccine, pcmv4 - lzp3, the cloned lzp3 full - length cdna was subcloned into a eukaryotic expression vector, pcmv4. these preliminary results could lead to further investigation for the development of immunocontraceptive vaccine based on lzp3 for lagurus population control
本工作首次克隆了草原兔尾鼠卵透明帶3全長cdna ，已向genebank申請注冊為新基因，保護了我國的野生動物基因資源，為哺乳動物生殖機理的研究提供了新的資料。The results of sequencing analysis show that the open reading frame ( orf ) of the cdna encodes a protein of 418 amino acids ( 45 kda ) that is significantly different from other published mammal zp3 sequences at a < wp = 7 > few sites. the result may have important implications for the elucidation of mechanisms of fertilization and the development of contraceptive vaccine based on lzp3
將其與genebank中多種哺乳動物zp3cdna進行同源性比較后，發現草原兔尾鼠與布氏田鼠zp3cdna編碼的蛋白前體的某些位點顯著不同於其它哺乳動物，其後續研究可能有助於哺乳動物受精機理的闡明與免疫不育疫苗的設計。分享友人
