Immunofluorescence micrographs of transverse sections of tracheids of OW and three CWs labelled with LM5. OW (a) MCW1 (b), MCW2 (c) and SCW (d). There is extremely weak fluorescence of the tracheid walls in the tracheid walls of OW (a). Computer enhanced brightening of the selected region shows the CML, probably the primary walls, is the structure labelled (inset in (a) at the same scale). In MCW1, there is a thin band of fluorescence in the outer region of the S2 layer (S2L) which is brighter at the cell corners (b). In MCW2, this fluorescent band is wider and brighter than in MCW1, with the brightest part again at the cell corners (c). In SCW, this fluorescent band is even wider and brighter, but is of similar brightness all around the cell (d). All sections were from Tree 1. Scale bar: 10 μm
