Pharyngeal sense organs drive robust sugar consumption in Drosophila

Pharyngeal sense organs drive robust sugar consumption in Drosophila

The fly pharyngeal sense organs lie at the transition between external and internal nutrient-sensing mechanisms. Here we investigate the function of pharyngeal sweet gustatory receptor neurons, demonstrating that they express a subset of the nine previously identified sweet receptors and respond to stimulation with a panel of sweet compounds. We show that pox-neuro (poxn) mutants lacking taste ...

The formation of sense organs in Drosophila: a logical approach.

The genetic analysis of development has revealed the importance of small sets of interacting genes in most morphogenetic processes. The results of gene interactions have so far been examined intuitively. This approach is largely sufficient when one deals with simple interactions, a feedback circuit for example. As more components become involved, however, it is difficult to make sure that the i...

The determination of sense organs in Drosophila: effect of the neurogenic mutations in the embryo.

We have examined the early pattern of sensory mother cells in embryos mutant for six different neurogenic loci. Our results show that the neurogenic loci are required to restrict the number of competent cells that will become sensory mother cells, but are not involved in controlling the localization or the position-dependent specification of competent cells. We conclude that these loci are invo...

The Physiology of Sense Organs

to the non-sporeforming anaerobes (Bacteroidaceae, anaerobic cocci, Lacto-bacteria and Corynebacteria, Actinomycetes). The book by Smith and Holdeman, published as part of the American Lecture Series in Clinical Microbiology, fills a void. Both authors have been working in the Anaerobic Bacteriology Laboratory at the Virginia Polytechnic Institute for years and draw on extensive experience, par...
