Flowering plants have evolved multigene families of the class XI myosin motors, the functions of which remain poorly understood. Here, we investigated functional profiles of the Arabidopsis myosins that belong to two paralogous pairs, XI-K/XI-1 and XI-2/XI-B, using single and double gene-knockout mutants. It was found that the myosins XI-K, XI-2, and XI-B, but not XI-1 have overlapping and additive roles in the root hair elongation. A nonidentical set of the three myosins, XI-K, XI-1, and XI-2, ...[more]
