tendon cell & actin filament, with Scer\GAL4how-24B, Scer\GAL4sr-md710
tendon cell & microtubule, with Scer\GAL4how-24B, Scer\GAL4sr-md710
Wing blisters are seen in 100% of shotdsRNA.Scer\UAS, Scer\GAL4Bx-MS1096 animals. When shotdsRNA.Scer\UAS is driven by Scer\GAL4sr-md710 and Scer\GAL4how-24B, larvae do not grow, remain at first and second instar stages for a few days and eventually die. Tendon cells lose their compact morphology and become very elongated (often three to four times the length of wild-type). However their association with the muscle and with the cuticle is maintained. levels of microtubules (MTs) at muscle-tendon junctions are greatly reduced. Often MTs are significantly elongated in the mutant tendon cell. Also ectopic Actin filaments are formed and detected between the cuticle and the muscle-tendon junction domains. These Actin bundles are independent of MT presence and are detected in cells in which MTs are still observed.
dsRNA is expressed from the template to study the phenotypic consequences of dsRNA interference (RNAi) of the shot gene.
