trisomic

Studies of genes related to heart development in drosophila contribute to reveal the mechanisms of human heart development and the congenital heart diseases . to clone and identify new genes that control the heart development , by a way of chemical mutagen , ems , we have established 1 , 200 balanced - lethal lines on chromosome 2 and 3 . with the screening the 330 stocks with immunochemical method using heart - specific antibody , mab . no . 3 , we detected 60 lethal lines showing heart mutant phynotype
为了克隆和鉴定控制心脏发育的新基因，本研究利用化学诱变剂甲磺酸乙酯大规模地诱变果蝇，并且建立了1200个第二和第三染色体的平衡致死系，利用心脏组织特异抗体mab . no . 3对其中330个品系进行免疫化学方法筛选，观察到有60个致死系表现出心脏突变表型， 20个品系的心脏突变表型有待进一步证实。
