Fig. 4

Immunogold micrographs of transverse sections of tracheids of OW and three CWs labelled with LM5. OW (a) MCW1 (b), MCW2 (c) and SCW (d). In the OW, only occasional particles (circled) are present over the CML, probably the primary wall of OW (a). In MCW1, particles are present as a band in the outer S2 layer (S2L) particularly at the cell corners, with smaller amounts in the S1 layer (b). The labelling density of the band increases with CW severity, particularly from MCW 1 to MCW 2 (c) in the S2L. The band of labelling in the SCW wall extends into the regions with helical cavities (HC) (d). All sections were from Tree 1. Scale bar: 1 μm
