Drosophila overview

Figure 23.5 Overview of pathways for olfactory processing in the Drosophila brain. Schematic outline of major wiring principles in the olfactory system (not to scale).

Figure 4.3. The NCBI Desktop displays a graphical overview of how the record is structured in memory, based on the NCBI data model (see Chapter 2). This view is most useful to a software developer or database sequence annotator. In this example, the submission contains a single Nuc-prot set, which in turn contains a nucleotide and two proteins. Each sequence has features associated with it. BioSource and publication descriptors on the Nuc-prot set apply the same organism Drosophila melanogaster) and the same publication, respectively, to all sequences.

Space does not permit here an extensive presentation of the methods of EM immunolabeling. We provide an overview and some illustrations, but for further details, see McDonald (1994) and more general references such as the books by Griffiths (1993), Hayat (1989b,c, 1991), and Newman and Robot (1993). For the most up-to-date articles on EM immunolabeling, although not usually on Drosophila tissues, consult recent issues of the Journal of Histochemistry and Cytochemistry.
