| | | [C.elegansII] it46ts,mat : homozygous hermaphrodites produce 90% (16C) to 99% (25C) arrested embryos, escapers sterile; abnormal early cleavages, both spindles transverse at 2nd cleavage (failure of P1 rotation), defective P granule localization. ES3 (progeny). OA7: it5ts (weaker phenotype), e2030 (Mes, grandchildless),it87 (weak),jb2, etc. All ts; temp shift indicates not needed after 2nd cleavage. Cloned: encodes predicted novel protein. Antibody staining indicates specific asymmetric cortical localizations in early blastomeres. [Cheng et al. 1995; KK] |
