Df(2L)flp170B does not protect Df(1)su(s)R194/+ clones in the eye; Df(1)su(s)R194/+ ; Df(2L)flp170B clones are not recovered in the adult eye in animals with mosaic eyes containing two genotypes of cells with respect to RpL36; cells which are Df(1)su(s)R194/+ and cells in which the haplo-insufficiency of Df(1)su(s)R194/+ for RpL36 has been rescued by RpL36+t4 (in a wild-type background the Df(1)su(s)R194/+ clones are eliminated by cell competition and are not seen in the adult eye in these animals). Also, the proportion of Df(1)su(s)R194/+ cells in the larval eye disc is not increased by the presence of Df(2L)flp170B.
Df(2L)flp170B mutant clones in sensory neurons in adult wing do not display any defects in injury-induced axon degeneration (following an axotomy, the severed axons are cleared away normally).
The size and number of paraquat-induced autophagosomes are reduced in Df(2L)flp170B clones in the larval midgut epithelium compared to controls.
Df(2L)flp170B clones in larval intestinal epithelial cells or fat body cells show a similar induction of autophagy as wild type clones upon starvation.
Df(2L)flp170B clones in the larval fat body cell show a similar induction of autophagy as in wild type clones at the late third instar stage - a stage when animals prepare to pupate and sustained autophagy is observed in these cells.
Df(2L)flp170B follicle cell clones cease mitotic division too early, resulting in clones that contain approximately half the number of cells as their respective twin spots. In addition, the cells in Df(2L)flp170B clones have larger nuclei than the neighboring wild-type cells.
Df(2L)flp170B somatic clones in the pupal eye discs (48 hours after puparium formation) have only a few extra interommatidial cells.
Mosaic animals in which the eye is largely homozygous for Df(2L)flp170B (generated using the "eyFLP" system) have larger eyes than normal.
Eggs derived from females with homozygous clones in the follicle cells show a a variety of dorsal appendage defects ranging from partial to complete absence of elongation and an accompanying expansion of their bases. The micropyle is reduced in size and sometimes has a truncated shape, looking incompletely "closed".
