Morphology of xylem and interfascicular fibers of WT, irx9, irx14 and MlGT43 complemented plants. Stems of eight-week-old plants were sectioned (8 μm-thick) and stained with TBO for examination of the morphology of vessels, xylary fibers and interfascicular fibers. A1-I1, interfasicular fibers for WT, irx9 and MlGT43 complemented irx9 plants. A2-I2, interfasicular fibers for WT, irx14 and MlGT43 complemented irx14 plants. J1-R1, xylary fibers and vessels for WT, irx9 and MlGT43 complemented irx9 plants. J2-R2, xylary fibers and vessels for WT, irx14 and MlGT43 complemented irx14 plants. At least two homozygous T3 lines of MlGT43s complemented irx9 or irx14 were used in the analysis. Images for each tissue are set as the same magnification. Bar = 50 μm
