Work continues on the study of sperm and fertilization. Johji Miwa and Sam Ward finally separated the chemotaxis from the sterile phenotype in E1034 by recombination. The reisolated temperature sensitive still makes sperm that fail to fertilize eggs. We have designated such mutants fertilization defective, fer. Several additional mutants of this phenotype have been isolated and are being studied. Such mutants are a subset of spermatogenesis defective mutants distinguished by the presence of sperm in the hermaphrodite. Yair Argon has prepared an anti-sperm antisera that will be used for immunological characterization of the sperm in fertilization defective mutants.
