Fig. 5.

Differentiation, and therefore transcription, occurs normally within cells that have mutations which prevent/mimic globular domain histone H3 modifications. a–n Eye imaginal discs with GFP-negative mutant clones generated using heat-shock FLP. Merged images show the nuclear marker DAPI in blue, the neuronal marker ELAV in magenta, and GFP⁺ and GFP⁻ regions demarcate histone wild-type cells and histone mutant cells, respectively. Grayscale images are the indicated individual channels
