Severe paralysis at the 1-fold stage of embryonic development followed by an arrest in elongation at 2-fold stage (PubMed:8106547). Loss of myosin and actin organization in embryonic body wall muscles and loss of muscle cell polarization (PubMed:8106547). RNAi-mediated knockdown in post-hatching animals causes paralysis associated with severe disorganization of body wall muscle actin filaments and defects in egg-laying associated with embryonic hatching within the mother (the bag of worms phenotype) (PubMed:12915588). Few surviving adults, are uncoordinated with abnormal body size and shape and have defects in distal tip cells (DTC) migration resulting in abnormal gonad formation (PubMed:17606640). RNAi-mediated knockdown in L4 larval stage, causes ectopic membrane extensions from body wall muscles (PubMed:16495308). RNAi-mediated knockdown results in impaired mobility, mitochondrial fragmentation and disrupted integrin attachment complexes in muscle (PubMed:22253611). This leads to degradation of muscle proteins in the cytosol, myofibrillar defects and disruption of sarcomere organization (PubMed:22253611). RNAi-mediated knockdown in vulval precursor cells in a let-60 gain of function mutant background results in increased vulval induction and an adjacent primary fate (Apf) phenotype whereby secondary vulval precursor cells transform into primary-like vulval cells (PubMed:28135265). {ECO:0000269|PubMed:12915588, ECO:0000269|PubMed:16495308, ECO:0000269|PubMed:17606640, ECO:0000269|PubMed:22253611, ECO:0000269|PubMed:28135265, ECO:0000269|PubMed:8106547}. |
