【摘要】 果蝇中,wⁿ 是由于转座因子 copia 对红眼基因的第二内含子的插入造成的,表型为杏黄色眼。调控基因 E（wⁿ）影响着 wⁿ 的表达而使 wⁿ 果蝇眼色变浅.我们用γ射线诱变得到一个 E（wⁿ）的回复子,纯合致死,致死作用发生在幼虫期。在红眼基因的十一个等位基因中,E（wⁿ）只影响 wⁿ、wⁿ⁴、wⁿ、w^np55、w^nRM和 w^nR844的表达,它们均为红眼基因的转座因子的插入突变等位基因。但 E（wⁿ）^R 对这些等位基因同时失去调控作用.E（wⁿ）与 wⁿ 的其它调控基因 su（wⁿ）,su（f）和 Doa 对 wⁿ 表达的调控是独立的。E（wⁿ）初步定位于第二染色体右臂的59F—60B的位置。更多还原

【Abstract】 In Drosophila melanogaster,the （?） allele resullts from the insertion of the transposable elementcopia within the second intron of the while locus,The w^? flies have the apricot eye colour.The eye colourof （?） flies with E（?） become much lighter.One revertant of thre E（?） was generated by the irradia-tion with γ-ray,it is recessive lethal with death occuring during the larval stage.The expression of the（?）and （?） in 11 alleles of the w⁺ were affacted by the E（?）,but not by the E（?）.These alleles are insertion mutations of w⁺ with transposable element.The regulative effect ofthe E（?） on the expression of the （?） is independent of other modifiers of the （?）,such as su（（?））,su（∫） and E（?）.The E（?） was preliminarily located at 59F-60B on the right arm of the thrid cvhro-mosome.更多还原
