ots1 ots2 Double Mutants Are Salt-Sensitive.

(A) Phenotypes of representative ots1 (ots1-1), ots2 (ots2-1), and ots1 ots2 (ots1-1 ots2-1) 12-d-old seedlings compared with wild-type Col-0. Top, seedlings were grown in the presence of 100 mM NaCl. Bar = 1 cm. Bottom, seedlings were grown in regular MS medium.

(B) Quantification of primary root growth on 100 mM NaCl expressed as a percentage relative to the untreated condition for each of the indicated genotypes. The experiment was performed independently four times with similar results. Error bars indicate se (n = 10 to 20).
