Figure 5.

Protonemata growing in the presence of magnetized wedges and magnetic and nonmagnetic particles. A, WT cells exposed to an HGMF for 8 h on a clinostat curve toward the wedge from both sides, as in Figure 2D. The projection of the wedge edge is shown as a long, horizontal line. Note that curvature decreases with increasing distance from the wedge edge. B, WT protonema curving around a magnetic particle. The protonemal culture was not clinorotated and curvature is thus the result of the magnetic force and gravity. C, Control wwr protonemata grow downward and are not influenced by the presence of a nonferromagnetic, brass particle. Arrows in B and C indicate the g vector. Bars = 200 μm.
