The dominant mutant “Soft and elongated trunk” (symbol Set) was found as an MNU-induced artificial gene mutation, which has been inherited in a sex-linked manner. It is characterized by the elongated 6th-7th body segments, making the body shape abnormally stretched. Hemizygous female individuals with respect to this gene are completely lethal at the embryonic stage. The Set gene was localized at the 35.5 position of the first linkage group on the basis of a three-point experiment involving os and sch as marker genes.
