摘要
异源DNA诱导遗传性变异的研究,近年来受到广泛的重视。周光宇教授经过广泛的实地调查,认为远缘DNA片段在母本DNA复制过程中,有可能被重组而使子代出现变异。因而她提出了常规远缘杂交中,存在着DNA片段杂交的假设(周光宇等,1979),我们曾用家蚕DNA或DNA蛋白,分别注入蓖赞蚕幼虫体内,结果后代发生了幼虫皮斑性状的改变(陈元霖等,1981)。本文报告我们用家蚕DNA诱导蓖麻蚕产生无洞茧的试验结果。
Bombyx mori DNA was injected into the body cavity of Attacus cynthia ricini pupae.It was found a small fraction of holeless cocoon appeared in the latter’s progenies (F1).Amino acid contents of fibroin of holeless cocoon,B.mori cocoon and Attacus cynthia ricini cocoon were compared.Amino acid contents of holeless cocoon fibroin seemed to be the same as that of Attacus cynthia ricini cocoon.
