Fig. 8. Effects of the FIL::NUB transgene on valve growth and cell layer proliferation. (A,B) SEM images of stage 13 gynoecia from the JD148-A transgenic line taken from the replum side (A) and valve side (B). Note the extension of valve tissue into the style region (B, white arrowhead). (C-H) Plastic-thin sections of gynoecia (C,D), sepals (E,F) and petals (G,H) from wild type (C,E,G) and the FIL::NUB transgenic line JD148-A (D,F,H). Tissue layer proliferation is seen in the medial region of the valves (brackets), in irregular locations in sepals (arrowheads) and throughout the petals of JD148-A flowers. Scale bars: 50 µm.
