The cell wall is a complex structure mainly composed of
cellulose microfibrils embedded in a cohesive hemicellulose and pectin
matrix. Cell wall structural proteins, enzymes and their inhibitors are
also essential components of plant cell walls. They are involved in the
cross-link of cell wall polysaccharides, wall structure, and the
perception and signaling of defense-related elicitors at the cell
surface. In the outer part of the epidermal cells, the polysaccharides
are coated by the cuticle, consisting of hydrophobic cutin, suberin and
wax layers. Lignin, a macromolecule composed of highly cross-linked
phenolic molecules, is a major component of the secondary cell wall. The
cell wall is the first cell structure on which interactions between
plants and a wide range of other organisms, including insects,
nematodes, pathogenic or symbiotic micro-organisms take place. It not
only represents a barrier that limits access to the cellular contents
that provide a rich nutrient source for pathogens but serves as a source
of elicitors of plant defense responses released upon partial enzymatic
degradation of wall polysaccharides during infection. Modification of
the plant cell wall can also occur at the level of plasmodesmata during
virus infection. The fine structure and composition of the plant cell
wall as well as the regulation of its biosynthesis can thus strongly
influence resistance and susceptibility to pathogens. We welcome
research papers, short communications, reviews, and methods focused on
the impact of plant cell wall in plant-pathogen and symbiotic
interaction.
