Single P-element (P[lArB]) insertional mutagenesis of an isogenic strain was used to identify autosomal loci affecting odor-guided behavior of Drosophila melanogaster. The avoidance response to benzaldehyde of 379 homozygous P[lArB] element-containing insert lines was evaluated quantitatively. Fourteen smell impaired (smi) lines were identified in which P[lArB] element insertion caused different degrees of hyposmia in one or both sexes. The smi loci map to different cytological locations and probably are novel olfactory genes. Enhancer trap analysis of the smi lines indicates that expression of at least 10 smi genes is controlled by olfactory tissue-specific promoter/enhancer elements.

D004251 DNA Transposable Elements Discrete segments of DNA which can excise and reintegrate to another site in the genome. Most are inactive, i.e., have not been found to exist outside the integrated state. DNA transposable elements include bacterial IS (insertion sequence) elements, Tn elements, the maize controlling elements Ac and Ds, Drosophila P, gypsy, and pogo elements, the human Tigger elements and the Tc and mariner elements which are found throughout the animal kingdom.
