Fruit flies help Yale scientists sniff out new insect repellents
Date:9/22/2010

hort the regulatory region could be and yet still control the test gene normally. This helped Miller to identify where the important control elements lie in the regulatory DNA, and whether they serve to turn the gene on in cells where it is needed or to turn the gene off where it doesn't belong.

"The sense of smell is an Achilles heel for many insects," said Mark Johnston, Editor-in-Chief of the journal GENETICS, "and the more we learn about odor receptors the easier it will be to interfere with them to battle insect-borne disease and crop devastation. This study is a step forward in doing that by identifying the mechanism that results in the highly selective expression of 'smell genes'."
