Trehalose sensitivity of the gustatory receptor neurons expressing wild-type, mutant and ectopic Gr5a in Drosophila.
Among ~70 candidate gustatory receptor genes identified from the Drosophila genome, Gr5a is the only gene that is allelic to a known gene, Tre, which controls taste sensitivity. Tre was discovered as an X-linked genetic polymorphism (Tre+ and Tre01) among wild populations and laboratory strains (Tanimura et al., 1982). Recent molecular studies on Gr5a and other gustatory receptor genes supporte...
متن کاملTrehalose sensitivity in Drosophila correlates with mutations in and expression of the gustatory receptor gene Gr5a
Drosophila taste gene Tre is located on the distal X chromosome and controls gustatory sensitivity to a subset of sugars [1, 2]. Two adjacent, seven-transmembrane domain genes near the Tre locus are candidate genes for Tre. One (CG3171) encodes a rhodopsin family G protein receptor [3, 4], and the other (Gr5a) is a member of a chemosensory gene family encoding a putative gustatory receptor [5-7...
متن کاملA Drosophila Gustatory Receptor Required for Strychnine Sensation.
Strychnine is a potent, naturally occurring neurotoxin that effectively protects plants from animal pests by deterring feeding behavior. In insects, such as the fruit fly, Drosophila melanogaster, bitter-tasting aversive compounds are detected primarily through a family of gustatory receptors (GRs), which are expressed in gustatory receptor neurons. We previously described multiple GRs that eli...
متن کاملDrosophila TRPA1 channel mediates chemical avoidance in gustatory receptor neurons.
Mammalian sweet, bitter, and umami taste is mediated by a single transduction pathway that includes a phospholipase C (PLC)beta and one cation channel, TRPM5. However, in insects such as the fruit fly, Drosophila melanogaster, it is unclear whether different tastants, such as bitter compounds, are sensed in gustatory receptor neurons (GRNs) through one or multiple ion channels, as the cation ch...
متن کاملSelection for Temperature Sensitivity in Scute Drosophila.
HE concept of canalisation as a system by which potential variation is channelled during development into a fairly uniform phenotype was put forward by WADDINGTON (1942). The term canalisation will here be used to mean a developmental buffering system by which potential variability is reduced and a relatively invariant phenotype is produced. If the canalisation system is upset by environmental ...
