Anatomical 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)
