Growth and cell survival are unevenly impaired in pixie mutant wing discs.

Abstract excerpt

It is largely unknown how growth slows and then stops in vivo. Similar to most organs, Drosophila imaginal discs undergo a fast, near-exponential growth phase followed by a slow growth phase before final target size is reached. We have used a genetic approach to study the role of an ABC-E protein, Pixie, in wing disc growth. pixie mutants, like mutants in ribosomal proteins genes (known as Minutes), show severe...
