peb1/pebhnt-1 and peb1/pebEH704a transheterozygous egg chambers show a significant decrease in follicle rupture (ex vivo, octopamine-treated egg chambers), as compared to peb1 heterozygous controls.
peb1/Y flies raised at the restrictive temperature have a rough eye phenotype, due to disorganisation of the facets.
Homozygotes raised at the restrictive temperature have a rough eye phenotype due to disorganisation of the facets. 2.8% of ommatidia are fused. Many ommatidia are missing photoreceptor cells; 43% lack outer cells, 1% lack central cells and 11% lack central and outer cells. 12% of ommatidia have extra photoreceptor cells. The eye bristles are sometimes mispositioned and show a variation in size not seen in wild type. The temperature sensitive period for external eye roughness spans from the mid-third instar to early pupal stages. 4.2% of photoreceptor cells have enlarged rhabdomeres. 22% of ommatidial preclusters from larvae raised at the restrictive temperature have missing gl-expressing cells, 30% have displaced gl-expressing cells and 17% have additional posterior gl-expressing cells.
Eyes markedly rough at 28oC-30oC, slightly rough (like S) at 25oC, and wild type at 19oC. RK2 (28oC-30oC).
