Accumulation of lignin in OsTF1 L^OX, OsTF1 L^{RNA i} transgenic rice and control plants. (a) Lignin contents in 2‐month‐old OsTF1 L^OX, OsTF1 L^{RNA i} and nontransgenic (NT) rice plants. Data bars represent the mean ± SD of three biological replicates (n = 3), each of which had two technical replicates. Asterisks indicate significant differences compared with NT (P < 0.05, one‐way ANOVA). (b–g) Transverse hand sections of phloroglucinol‐HCl stained 3‐month‐old mature shoots of NT (left), OsTF1 L^OX (middle) and OsTF1 L^{RNA i} (right) plants. (e–g) are enlarged views of the dotted line boxes in (b), (c) and (d), respectively. ls, leaf sheath; is, inflorescence stem; p, pith; va, vascular bundles; ep, epidermis; sc, sclerenchyma tissues.
