β-Cat knockdown prevents Abl4 mutant CySC clones from outcompeting their neighbors and taking over the niche.

aTestes with CySC clones = testes with GFP+, Zfh-1+ cells/total testes scored (percentage).bTestes with >50% marked CySCs = testis where GFP+, Zfh-1+ cells>GFP−, Zfh-1+ cells/total testes scores (percentage).cWild type clones expressing β-Cat RNAi = Wild type Frt 40A MARCM flies driving β-Cat RNAi specifically in induced clones.dAbl4 clones expressing β-Cat RNAi = Abl4 MARCM flies driving β-Cat RNAi specifically in induced clones.eP value vs Abl4 clones.ND = Not Determined, ACI = After Clone Induction,* = P value** = P valueβ-Cat knockdown prevents Abl4 mutant CySC clones from outcompeting their neighbors and taking over the niche.
