In
this article, various situations in the hosts studied are presented
showing the relationship between the presence of structures (called
P-elements) in host cell walls and of their alterations and/or
reactions, as of those occurring in the adjoining cells. Whereas these
structures predominate in middle lamellae between cells lacking
secondary walls, they are mostly located in pit membranes of
paratracheal cells in the secondary xylem. The opaque matter also
involved in extensive host tissue invasion likewise contains similar
structures. A parallel was noted between the abundance of these
structures and the intensity of the alterations observed. The structures
in question were observed to be structurally similar to those occurring
in nuclei (as shown in article IV).
