Figure 2.

Root hair development in the knockout mutants and transgenic plants expressing a dominant negative mutant of the myosin XI-K. A, Typical images of the roots for the control (Columbia) and four knockout lines are shown as indicated. XI-K/GTD is a transgenic line expressing GTD of the myosin XI-K. B, Analysis of the mean root hair length for the lines shown (A). C, Immunoblot analysis of the HA epitope-tagged XI-K/GTD expression using HA-specific monoclonal antibody. Samples were from a control plant (C in the image) and plants representing three independent transgenic lines (1, 2, and 8). Positions of two size markers (molecular mass in kilodaltons) are shown by arrows.
