Domains of Lid that are essential for development.

Rescue of lid10424 by Lid deletion transgenes: 7 female flies of the genotype shown in left column were crossed to lid10424/CyO; Actin-Gal4/TM3 at 25°C and the progeny scored. Genotypes not shown were obtained at the expected Mendelian frequency.*indicates that the number of lid10424/lid10424 UAS-Lid transgene; actin-Gal4 flies obtained were significantly more than control crosses lacking the transgene (chi squared test).$All flies of this genotype died within several days of eclosing.
