Auxin–ethylene double mutant analysis of ABA-responsive inhibition of primary root elongation. Mean primary root lengths (±SE; n ≥ 12) of Col-0, eto1, ein2, eto1 ein2, ibr5, eto1 ibr5, ein2 ibr5, tir1, eto1 tir1, ein2 tir1, axr1, eto1 axr1, aux1, eto1 aux1, and ein2 aux1 seedlings grown under yellow-filtered light at 22° for 4 d on unsupplemented medium, followed by 4 d on medium supplemented with ethanol (mock) or 10 µM ABA. eto1 ibr5, eto1 tir1, eto1 axr1, and eto1 aux1 root lengths were significantly (P ≤ 0.001) longer than the eto1 root length on ABA. ein2 ibr5, ein2 tir1, and ein2 aux1 root lengths were statistically indistinguishable from the ein2 root length on ABA, whereas ein2 axr1 root lengths were significantly longer than either ein2 or axr1 root lengths (P ≤ 0.001) on ABA.
