Cutin monomer profiles of Arabidopsis rosette leaves from plants subjected to water deficit (A), 150 mm NaCl (B), 10 μm ABA (C), or 100 μm ABA (D). ABA-treated plants and their respective controls were greenhouse grown. Methanol was used to dissolve ABA, which was diluted to treatment concentrations with distilled, deionized water. Control plants for ABA treatments were sprayed with distilled, deionized water containing an equivalent amount of methanol. NaCl-treated, water deficit-treated, and their respective control plants were grown in a growth room. Bars represent mean values ± sd (n = 3–4, the experiments were repeated once with similar results). Asterisks denote significant differences (*, P < 0.05; **, P < 0.01) as determined by Student's t tests or Satterthwaite t tests.
