Olfactory Receptor Neurons Select Which Odor Receptors To Express

Scientists have looked at the problem of understanding the regulatory mechanisms that create different cells from a single template by using the olfactory system of the fruit fly. The ability to discriminate odors depends on receptor cells expressing different patterns of receptor genes, despite each cell having the same genes. Receptor patterns are controlled by DNA sequences upstream of the receptor genes.
