An Arabidopsis thaliana tubulin mutant with conditional root-skewing phenotype.

Abstract excerpt

Low doses of microtubule-interacting drugs cause wild-type Arabidopsis thaliana seedling roots to twist in a left-handed helical direction. We here report molecular characterization of an A. thaliana tubulin mutant whose roots twist in a right-handed direction and have shallow left-handed cortical microtubule arrays when challenged with low doses of microtubule drugs. In the absence of the drug, growth and...
