Analysis of lignin content in WT and miR319 transgenic plants. a, b Phloroglucinol–HCl staining assay of lignin content in the middle of the first internode of E3 stage cross-sections (a) and in the dry materials powder of stems (b). C collenchyma, VT vascular tissue. Scale bars indicate 5 μm. c The Klason lignin content of dry materials of stems. Data are shown as the mean ± SD (N = 3, n = 5). Different letters and asterisks represent significant differences compared to WT (P < 0.05)
