图6 石蜡切片比较GhMADS7-RNAi转基因植株和野生型‘YZ1’的花瓣构造 iGhMADS7: 抑制GhMADS7转基因植株; YZ1: 野生型植株。(2~3) mm~(7~8) mm代表花蕾的发育长度。El: 上表皮细胞; Hl: 下表皮细胞; Pt: 薄壁组织; Vb: 维管束。8、10、12代表薄壁组织的细胞层数。图WT和iGhMADS7-27的标尺均为20 µm。

Fig. 6 Comparison of petal structure between GhMADS7-RNAi transgenic plants and wild type YZ1 by paraffin section iGhMADS7: suppression of GhMADS7 transgenic plants; YZ1: wild type plants. 2-3 mm to 7-8 mm represents the length of the bud. E1: epithelium cells; H1: hypodermic cells; Pt: thin-walled tissue; Vb: vascular bundle. 8, 10, 12 represent the cell layer number of the thin-walled tissue. Bar = 20 µm (in WT and iGhMADS7-27).
