Fig 12

Ultramicroscopic observation of cell walls in the inflorescence stems of WT and transgenic lines.

TEM images of the ultrastructure of the cell wall. (A) WT plants; (B) PbLAC1-overexpressing transgenic plants; (C) PbLAC14-overexpressing transgenic plants; (D) Statistical analysis of the secondary cell wall thickness of vessel cells in WT and transgenic plants. ** Significant difference between the secondary cell wall thickness of the WT and transgenic plants (P < 0.01).
