Wiesner (a) and Mäule (b) staining of hand-cut stem sections from transgenic plants harboring F5H, calB, couA, or F6H1 transgenes. The sections were prepared from 8-week-old T1 transgenic plants generated by the transformation of single Agrobacterium strains harboring PkC4Hpro::F5H, PkC4Hpro::calB, PkC4Hpro::couA, or PkC4Hpro::F6H1 constructs. The representative image for each line is presented. The lower panels are magnified images of corresponding upper panels. Scale bars = 100 μm
