在这里,我们描述了胚胎中枢神经系统表达的5,000 GAL 4线使用分子定义的顺式调节DNA插入到一个单一的attP基因组位置。我们记录并注释了早期胚胎中神经发生处于高峰时的模式,以及在较老的胚胎中,神经元多样性最大,第一个神经回路建立。我们注意到在其他组织中的表达,如侧体壁(肌肉,感觉神经元,气管)和内脏。相关论文报告了成年大脑和幼虫的影像盘,综合数据集可在网上查阅(www.janelia.org/flylight/gal4-gen1)。这种胚胎表达的GAL 4系的集合对于确定神经元形态和功能将是有价值的;在神经元的小子集(<20个/节段)中表达的1862个系对于表征神经元间多样性和功能将是特别有价值的,因为神经元间包括所有CNS神经元的大部分,然而它们的基因表达谱和功能仍然几乎未被探索。
Here we describe the embryonic CNS expression of 5,000 GAL4 lines made using molecularly defined cis-regulatory DNA inserted into a single attP genomic location. We document and annotate the patterns in early embryos when neurogenesis is at its peak, and in older embryos where there is maximal neuronal diversity and the first neural circuits are established. We note expression in other tissues such as the lateral body wall (muscle, sensory neurons, trachea) and viscera. Companion papers report on the adult brain and larval imaginal discs, and the integrated datasets are available online (www.janelia.org/flylight/gal4-gen1). This collection of embryonically-expressed GAL4 lines will be valuable for determining neuronal morphology and function; the 1862 lines expressed in small subsets of neurons (<20/segment) will be especially valuable for characterizing interneuronal diversity and function, as interneurons comprise the majority of all CNS neurons, yet their gene expression profile and function remain virtually unexplored.
