mummy/cystic encodes an enzyme required for chitin and glycan synthesis, involved in trachea, embryonic cuticle and CNS development--analysis of its role in Drosophila tracheal morphogenesis.

Abstract excerpt

Tracheal and nervous system development are two model systems for the study of organogenesis in Drosophila. In two independent screens, we identified three alleles of a gene involved in tracheal, cuticle and CNS development. Here, we show that these alleles, and the previously identified cystic and mummy, all belong to the same complementation group. These are mutants of a gene encoding the...
