Mutations in alpha-tubulin promote basal body maturation and flagellar assembly in the absence of delta-tubulin.

Abstract excerpt

We have isolated suppressors of the deletion allele of delta-tubulin, uni3-1, in the biflagellate green alga Chlamydomonas reinhardtii. The deletion of delta-tubulin produces cells that assemble zero, one or two flagella and have basal bodies composed primarily of doublet rather than triplet microtubules. Flagellar number is completely restored in the suppressed strains. Most of the uni3-1 suppressors map to the...
