Influence of electrical fields and asymmetric application of mucilage on curvature of primary roots of Zea mays.

Primary roots of Zea mays cv. Yellow Dent growing in an electric field curve towards the anode. Roots treated with EDTA and growing in electric field do not curve.

Characterization of root agravitropism induced by genetic, chemical, and developmental constraints.

The patterns and rates of organelle redistribution in columella (i.e., putative statocyte) cells of agravitropic agt mutants of Zea mays are not significantly different from those of columella cells in graviresponsive roots.
