spalt encodes an evolutionarily conserved zinc finger protein of novel structure which provides homeotic gene function in the head and tail region of the Drosophila embryo.

Abstract

The region specific homeotic gene spalt (sal) of Drosophila melanogaster promotes the specification of terminal pattern elements as opposed to segments in the trunk. Our results show that the previously reported sal transcription unit was misidentified. Based on P-element mediated germ line transformation and DNA sequence analysis of sal mutant alleles, we… (More)
