Overexpression of PtrHB4mt induced ectopic vascular cambium and xylem cells. Cross section of the IN2 in PtrHB4mt (a, cortex and b, pith) and WT plants (c). Cross section of the IN12 in PtrHB4mt (d and e, indicating different areas of cortex) and WT plants (f). Secondary cell wall staining by phloroglucinol‐HCl in the cortex of PtrHB4mt (g and h, indicating different areas of cortex) and WT plants (i). All sections were sampled from three‐month‐old plants. ca, Cambium; eca, ectopic cambium; sxy, secondary xylem; exy, ectopic xylem; sph, secondary phloem; spf, secondary phloem fibre; co, cortex. Bars: 20 μm in (a), (b) and (c), 100 μm in (d), (e), (f), (g), (h) and (i).
