Fig. 8From: PcDWF1, a pear brassinosteroid biosynthetic gene homologous to AtDWARF1, affected the vegetative and reproductive growth of plantsAnatomical structure analysis of the transgenic lines and the control tobacco and pear plants, including the cross-section and the longitudinal section of the stems. a The anatomical structure analysis of the transgenic lines and the control tobacco plants. pc, parenchymal cell; xy, xylem; ph, phloem; p, pith. b The anatomical structure analysis of the transgenic lines and the control pear plants. c The diameter of the parenchymal cells in the stems of transgenic lines and the control tobacco and pear plants. d The thickness of the xylem of transgenic lines and the control tobacco and pear plants in cross-section. e The length of the parenchymal cells in the stems of transgenic lines and the control tobacco and pear plants in longitudinal section. Data are the means ± SD of triplicate experiments. Asterisks (*) indicate significant differences from the control (Student’s t-test, *P < 0.05, **P < 0.01)Back to article page
