Mature inflorescence stems were cross-sectioned for imaging of interfascicular fiber cell walls. (a) Stem epidermal cells showing the reduced thickness of cell wall in the PhCESA3-silenced plants (right) compared to the control plant (left). (b) Stem cortical cells showing similar cell wall thickness in PhCESA3-silenced plants (right) and wild-type plants (left). (c) Chloroplast of stem cortical cells showing the reduced starch granules in the PhCESA3-silenced plants (right) compared to control plants (left). (d) Stem xylem cells showing similar cell wall thickness in PhCESA3-silenced plants (right) and control plants (left). (e) Petal limb epidermal cells showing the reduced cell wall thickness in PhCESA3-silenced plants (right) compared to control plants (left). (f) Petal limb upper epidermal cells showing the change of cell shape in PhCESA3-silenced plants (bottom) compared to control plants (top). (g) Petal limb lower epidermal cells showing the change of cell shape and reduced cell wall thickness in PhCESA3-silenced plants (right) compared to control plants (left). (h) Filament epidermal cells showing the change of cell shape, cell size and reduced cell wall thickness in PhCESA3-silenced plants (right) compared to control plants (left). (i) Filament cortical cells showing changed cell shape and size but similar cell wall thickness in PhCESA3-silenced plants (right) compared to control plants (left). Bars = 10 μm in (a,b,f–i); bars = 1 μm in (c); bars = 2.5 μm in (d); bars = 5 μm in (e).
