Reduced root gravitropic bending and elongation as well as lateral root formation; reduced root elongation is conditional and dependent on light intensity and sucrose. Reduced basipetal auxin transport in roots (~35%) and a small decrease in shoot-to-root transport consistent with a partial loss of the redirective auxin sink in the root.
