Detailed Description
Statement
Reference

ecspok homozygous adult eyes display strong ommatidial displacement defects, with approximately 15% of ommatidia misoriented by more than 20 degrees with respect to the WT axis. In third instar imaginal discs, very rare orientation defects are observed, but by 24 hours after pupal formation (APF) pupal retina show robust rotation defects, disrupted sorting of the lattice, and extra interommatidial cells (including more primary pigment cells) aberrantly organised in multiple layers. This defect in programmed cell death is also evident at 42 hours APF, where an increase in lattice interommatidial cell survival is observed (~13 cells compared to 9 in wildtype), and the overall appearance of the lattice is highly disorganised.

ecspok/Df(1)GA102 adult eyes display strong ommatidial displacement defects, with approximately 15% of ommatidia misoriented by more than 20 degrees with respect to the WT axis.

ecspok/Df(1)HC244 adult eyes display strong ommatidial displacement defects, with approximately 15% of ommatidia misoriented by more than 20 degrees with respect to the WT axis.

ecspok/ec1 adult eyes display intermediate ommatidial orientation defects, reduced in frequency compared to ecspok homozygotes, but increased compared to ec1 homozygotes.

ecspok/ecKG09175 adult eyes display intermediate ommatidial orientation defects, reduced in frequency compared to ecspok homozygotes, but increased compared to ecKG09175 homozygotes.

ecspok/ecKG10228 adult eyes display intermediate ommatidial orientation defects, reduced in frequency compared to ecspok homozygotes, but increased compared to ecKG10228 homozygotes.
