Genetic interaction between UNC-87 and CeTM in body wall muscle. (A) Adult body wall muscle of wild-type (a–c) or unc-87(e1216) (d–f) animals was double stained with anti-actin (a and d) and anti-CeTM (b,e) antibodies. Merged images are shown in c and f (red: actin, green: CeTM). (B) Actin filament organization in adult body wall muscle was visualized by staining with tetramethylrhodamine-phalloidin. Wild-type (a–c), unc-87(e1216) homozygous (d–f), or unc-87(e1459) homozygous (g–i) animals were treated with control RNAi (a,d,g), CeTMI,II (RNAi) (b,e,h), or CeTMI,II,III,IV (RNAi) (c,f,i).
