Transport of IBA and IAA in auxin transport mutants

Transport	Columbia	aux1-7	eir1-1
		pmoles transported^a
Root basipetal
IAA	1.1 ± 0.1	0.6 ± 0.03^***	0.8 ± 0.05^***
IBA	1.7 ± 0.08	1.7 ± 0.1	1.8 ± 0.1

IBA	5.6 ± 0.6	5.6 ± 0.6	N.D.^b

^a Average and se of 23 to 30 seedlings from three experiments. The P values were obtained by two-tailed Student's t test for Columbia vs. mutant plants. **, P < 0.01; ***, P < 0.001. No significant differences in IBA transport were detected for these mutants. ^b N.D., Not determined.
