Primary Root Growth Is Not Affected in the ots1 and ots2 Single Mutants or in the ots1 ots2 Double Mutant

Genotype	Root Length ± sd (cm)
Wild type (Col-0)	5.0 ± 0.5
ots1-1	4.9 ± 0.5
Wild type (Col-0)	4.8 ± 0.3
ots2-1	4.8 ± 0.3
Wild type (Col-0)	4.5 ± 0.7
ots1-1 ots2-1	4.5 ± 0.3

Primary root growth rate of ots1 and ots2 mutants plants. Wild-type (Col-0), ots1-1 and ots2-1 single mutant, and ots1-1 ots2-1 double mutant seeds were sown on 0.5× MS agar plates and grown for 6 d. Wild-type and mutants seedlings were then transferred to fresh 0.5× MS agar plates so that each plate had both the mutant genotype and the wild-type control (n = 9 each). The root tip position (time point 0) was recorded, and additional root growth was measured 7 d after time point 0.
