铁是大多数生物的必需元素。本文分离了曼氏血吸虫两个编码铁蛋白亚基的cDNA克隆,并分析了它们的核苷酸顺序。作者将其与脊椎动物铁蛋白的基因序列作了详细比较,并探讨了铁蛋白基因在曼氏血吸虫雌、雄虫中表达的差异。以血吸虫成虫的poly(A)~+RNA为模板建立cDNA文库。将椎实螺软体部分的铁
Iron is an essential element of most living things. In this paper, two cDNA clones encoding ferritin subunits of Schistosoma mansoni were isolated and their nucleotide sequences were analyzed. The author compares the gene sequence of vertebrate ferritin with that of vertebrate ferritin, and discusses the difference of expression of ferritin gene in female and male Schistosoma mansoni. A cDNA library was constructed using poly (A) ~ + RNA from adult schistosomes as a template. The spinella soft body part of the iron
