^{a}The angle of curvature 24 hr after gravity stimulation in at least 27 plants from three experiments. The average ±se are reported.↵

^{b}P values are compared for wild type vs.*rcn1*at each concentration by Student's*t*test.↵

^{c}The P value for*rcn1*at 0 NPA vs.*rcn1*at 0.5 μM NPA compared by Student's*t*test is 0.020.
