Rho1 regulation of AJs is Cdc42/Par6 dependent. (a) Confocal immunofluorescent localization of DE-cadherin (DE-cad) in Rho1⁷² MARCM clones expressing Cdc42-RNAi. (b) Confocal immunofluorescent localization of DE-cadherin in Cdc42⁴ MARCM clones expressing Rho1-RNAi. (c) Confocal immunofluorescent localization of DE-cadherin in par6^Δ226 MARCM clones expressing Rho1-RNAi. (a–c) Arrowheads identify AJs between clonal cells. Bars, 10 µm.
