Phenotype: lacks flagella, does not mate

The bld or bald mutants were recovered as nonmating mutants in Goodenough’s laboratory, and were subsequently shown to lack flagella.

The bld2 mutant was characterized as defective in basal body formation, but having normal levels of centrin and a stable nucleus-basal body connector. Dutcher et al. showed that the defect is in the gene encoding epsilon tubulin. The bld2-1 allele has a premature stop codon in this gene.
