XTH30 affects cellulose synthesis under salt stress. (A) Seedlings germinated and grown for 6 d on 1/2 MS supplemented with or without 2 nM isoxaben in dark. Scale bar indicates 3 mm. (B) Quantification of hypocotyl elongation of seedlings in (A). Error bars represent SD, n>15 seedlings per biological replicate. Similar results were observed in three independent experiments. (C) Crystalline cellulose content of hypocotyl from xth30 mutants and wild type in response to salt stress. Error bars represent SD (n=3). The asterisks in (B, C) indicate a significant difference between xth30 mutants and wild type using unpaired Student’s t-test (**P<0.01).
