Abstract
This report describes studies of the compensatory response employing D. melanogaster stocks that bear cloned-X chromosomes derived from laboratory populations of strains Oregon R and Canton S. We find that modification of the autosomal background in either the female or the XY male parent influences the expression of the compensatory response by X chromosomes derived from the Canton S population, whereas Oregon R isolates are unresponsive to these effects. We have also studied compensatory replication in X/O larvae produced from cloned-X derivatives of both Canton S and Oregon R. Canton S larval compensation exceeds that of the adult, whereas in Oregon R the converse is true. We have concluded that both X chromosomal and autosomal factors affect the expression and magnitude of the compensatory response.
摘要
本报告描述了利用携带源自俄勒冈R和广东S品系实验室群体的克隆X染色体的黑腹果蝇品系进行的补偿反应研究。我们发现，雌性或XY雄性亲本中常染色体背景的改变会影响源自广东S群体的X染色体的补偿反应表达，而俄勒冈R分离株对这些影响无反应。我们还研究了由广东S和俄勒冈R的克隆X衍生物产生的X/O幼虫中的补偿复制。广东S幼虫的补偿超过成虫，而在俄勒冈R中情况则相反。我们得出结论，X染色体和常染色体因素都会影响补偿反应的表达和程度。
