Fig. 7From: Transcriptomic analysis of early fruit development in Chinese white pear (Pyrus bretschneideri Rehd.) and functional identification of PbCCR1 in lignin biosynthesisObservation of transverse section staining of inflorescence stems and determination of lignin contents in transgenic plants. a–f Toluidine blue staining of the inflorescence stems from wild-type (WT) and transgenic lines. a, c, e: bar = 100 μm. b, d, f: bar = 200 μm. F: interfascicular fibre; X: xylem. g–h Determination of lignin contents in inflorescence stems of Arabidopsis. Significant differences in lignin content levels between WT and transgenic overexpression lines of Arabidopsis were determined by a t test; *P < 0.05, **P < 0.01Back to article page
