Cell wall component analysis

(a) Sections stained with phloroglucinol-HCl in WT (a, b) and OE (c, d) plants; Xy, xylem. (b-e) Secondary cell wall composition of WT and OE plants, including lignin, S/G lignin ratio, cellulose, and hemicellulose. Data were represented as the mean ± SE of three biological replicates; asterisks indicate levels of significance (t-test; ∗ P < 0.05, ∗∗ P < 0.01).
