Figure 1.

Loss of lmg leads to elevated apoptosis in larval brain and imaginal discs. Orcein-stained preparations of wild-type (A) and lmg¹³⁸ (D) larval brain squashes. lmg mutants show small, rounded cells with uneven nuclear staining. Acridine Orange staining also highlights the high incidence of dying cells in lmg^J023 mutant wing imaginal disc (E) and lmg¹³⁸ larval brain (F) relative to wild-type tissues (B and C). Green dots indicate apoptosis. The lmg¹³⁸ null mutant (F) has reduced brain and optic lobes compared to wild-type (C).
