A mutant plant exhibits stunted root growth and reduced gravitropic response. Microscopic analysis reveals disorganized columella cells in the root cap. Which of the following is the MOST likely cause of this phenotype?
Increased production of cytokinin in the root tip
Disruption of amyloplast sedimentation and auxin redistribution
Overexpression of genes involved in cell elongation
Enhanced sensitivity to ethylene
