      Statement
      Reference

      Hvir\βt fails to support any microtubule assembly in βTub85D null mutants. When coexpressed with βTub85D, Hvir\βt poisoned all microtubule-mediated processes; spermatid nuclei are not shaped, spermatids are not aligned, spermatid elongation is defective, reflecting failure of axoneme assembly and mitochondrial derivative elongation.

      Drives expression in the postmitotic male germ cells with correct developmental specificity and level of expression. Construct obtains wild-type tubulin-like levels of expression.
