Overexpression of 43-kD SPDO during early- or late-myofibril assembly affects myofibril structure without affecting muscle function. Myofibrils from D2 adult hs-43 kD spdo flies (A) heat shocked at 12 PM D3 APF or (B) 12 PM D1 after eclosion. (Top) Bodipy-phallacidin staining for F-actin; (Bottom) anti-SPDO staining. Short white arrow, short “core” thin filaments; long white arrow, longer “peripheral” thin filaments; white arrowheads, pointed ends; Z, Z-disc. Bar, 5 μm.
