Phenotypic analysis of the Dopa decarboxylase gene cluster mutants in Drosophila melanogaster
Article Abstract:
Mutations in most of the 18 Dopa decarboxylase (Ddc) loci of Drosophila melanogaster produce similar cuticle and catecholamine-related disorders. Mutations in seven genes disturb catecholamine levels during pupal and prepupal development indicating that the genes probably encode proteins involved in catecholamine degradation. Mutations in 14 loci disturb cuticle formation, sclerotization or melanization, and mutations in 11 loci produce melanotic pseudotumors. The Ddc gene cluster is a large group of functionally related genes responsible for common physiological processes.

Inheritance, genetic interaction, and biochemical characterization of anthocyanin phenotypes in peach
Article Abstract:
An analysis of the localization of anthocyanins in the organs and tissues of three clones of peach indicates a regulated pathway for anthocyanin biosynthesis, wherein light, pathogens, growth and injury induce transcription. Allelic genes cause anthocyanin-deficient phenotypes in these clones. The absence of any enzyme in the biosynthetic pathway leads to anthocyanin deficiency.
