IR spectrophotometry analysis of the cell wall structure and composition of flax seedlings infected with Fusarium oxysporum. The IR spectra of samples from control flax seedlings (C), seedlings after F. oxysporum infection (F.ox.). a Changes in cellulose content presented as differences in the integral intensities of the bands at 1455 cm−1 (a), 1319 cm−1 (b), and 1161 cm−1 (c). b Changes in the structure of cellulose (C-O-C bonds) presented as differences in the integral intensities of the bands at 1058 cm−1 (a) and 988 cm−1 (b). c Changes in cellulose structure presented as differences in the integral intensities of the bands at 1230 cm−1, corresponding to δ (OH · · · O) (a) and 625 cm-1, corresponding to γ(OH•••O) (b). d Changes in pectin content presented as differences in the integral intensities of the bands at 1735 cm−1 (a), 1655 cm−1 (b) and 1609 cm−1 (c). e Changes in lignin content presented as differences in the integral intensities of the bands at 1337 cm−1 (a), 1260 cm−1 (b) and 1245 cm−1 (c)
