Moreover, each necklace neuron expresses multiple types of MS4A
receptors, in stark contrast to the one -
receptor - per - neuron rule that organizes
insect and other mammalian
olfactory systems.
As all three studied
insect species emerged at different times in
insect evolution, the scientists wanted to track the historical development of
olfactory receptors.
Christine Mißbach, first author of the study, analyzed the active genes in the
insect antennae where the
olfactory receptors are located and describes her discovery this way: «Astonishingly, the firebrat, which is more closely related to flying
insects, employs several co-
receptors, while the odorant
receptors themselves are absent.»
However, the researchers did not find any evidence for an
olfactory system which is based on odorant
receptors in the most basal
insect, the jumping bristletail.
They form a functional complex with another protein, the so - called
olfactory receptor co-
receptor, which enables
insects to smell the tiniest amounts of odor molecules in their environment very rapidly.
Next, the researchers tested whether neurons in the
insects»
olfactory receptors, or sensilla, responded to nonanal.
The discovery of odor - detecting
receptors in the fruit fly Drosophila may help scientists better understand how
insects and eventually other animals process
olfactory information and how odors...
