Differing expression of Scabrous in ato1 imaginal discs when atonal, Xath5, NeuroD, Math5, or scute are ectopically expressed. Confocal micrographs of Scabrous expression in the MF. (A) w-;gal4-7, ato1/TM6Tb control. Normal expression highlights ommatidial precluster formation within the morphogenetic furrow (MF). (B) In atonal-rescued eyes, Scabrous expression initiates immediately posterior to the MF in a broad band of cells. (C) Xath5-rescued eyes also initiate Scabrous expression immediately posterior to the MF similarly to atonal. (D) Math5 fails to activate Scabrous expression. The arrowhead points to the lone Scabrous-positive cell observed throughout these experiments. (E) scute induces randomly spaced Scabrous-expressing cells posterior to the MF. (F) The expression of Scabrous in NeuroD rescued eye discs was nearly identical to that of Xath5-rescues. Scale bar, 25 μm.
