Quantitative and compositional characterization of cell walls of Col-0 and N14 under different acclimation conditions. (a) Amount of total cell wall material under NA, CA, SZA and CA+ conditions in Col-0 and N14 relative to total rosette dry weight (DW). Error bars indicate ± s.e.m. (n = 4) and significant differences between treatments within an accession at p < 0.05 (Tukey-Kramer test) are marked with different letters above the bars. (b) Total cell wall material was separated into four different subfractions (Insoluble, CDTA-, NA2CO3- and KOH-soluble fractions). Proportional contributions of these subfractions to the total cell wall material are shown for the different acclimation treatments.
