minidiscs encodes a putative amino acid transporter subunit required non-autonomously for imaginal cell proliferation.

Abstract excerpt

Drosophila minidiscs mutant larvae have smaller imaginal discs than wild-type larvae. However, transplantation experiments have revealed that minidiscs mutant imaginal discs can grow if cultured in non-mutant hosts. These data suggest that minidiscs is required in one or more non-imaginal tissues for synthesis and/or secretion of a diffusible factor that stimulates imaginal cell proliferation. The 2. 3 kb...
