在早期发育过程中,黑腹果蝇的神经基因参与控制神经外胚层细胞的命运;杏仁糖(amx)属于这类基因。我们已经确定了amx基因座和挽救amx胚胎神经原性表型与1.5 kb的DNA片段。使用一个小的缺陷,我们产生了一个新的amx突变背景称为amxm,这是一个无效等位基因。除了amx缺失引起的特征性神经源性母体效应外,amxm果蝇还表现出类似Notch功能缺失的新的成虫表型。我们描述了胚胎中amx诱导的Notch途径靶点E(spl)m7的失调以及成年果蝇中amx和Notch途径突变体之间的遗传相互作用。这些数据表明,野生型amx作为Notch途径的一种新的正调节因子,在发育过程中需要不同的水平。创世纪37:113-122,2003。© 2003 Wiley利斯公司
During early development, the neurogenic genes of Drosophila melanogaster are involved in the control of cell fates in the neurectoderm; almondex (amx) belongs to this category of genes. We have identified the amx locus and rescued the amx embryonic neurogenic phenotype with a 1.5 kb DNA fragment. Using a small deficiency, we generated a new amx mutant background called amxm, which is a null allele. Besides the characteristic neurogenic maternal effect caused by loss of amx, amxm flies display a new imaginal phenotype resembling loss of function of Notch. We describe amx‐induced misregulation of the Notch pathway target E(spl) m7 in embryos and genetic interactions between amx and Notch pathway mutants in adult flies. These data show that wildtype amx acts as a novel positive regulator of the Notch pathway and is required at different levels during development. genesis 37:113–122, 2003. © 2003 Wiley‐Liss, Inc.
