Figure 6. Microcopy analysis of stems from 6-week-old plants.

The LM10 anti-xylan monoclonal antibody was used for immunodetection of xylan in transverse stem sections. The nomenclature for the constructs used to transform the irx9 and irx14 plants is explained in Table 1. Irregular xylem phenotype (indicated with arrows) was observed in the irx9 and irx14 mutants, as well as in the irx14 plants transformed with the 35S:IRX14-1 construct. All the other transformants showed normal vessel phenotype.
