In animals, one of the most immediate responses to tissue wounding comprises the release of peptide signals such as interleukins from their precursor proteins. Although the wound response has been intensively studied in plants as well, little is known about plant peptides with cytokine-like function...
Physical damage to cells leads to the release of immunomodulatory peptides in order to elicit wound defense responses in the surrounding tissue. In Arabidopsis thaliana, the intracellular PROPEP1 protein precursor is processed into the mature 2.5 kDa PEP1 before release. However, the maturation mech...
The structure and composition of plant cell walls are modified to accommodate the needs of the cell and in response to environmental stimuli. Growth, development, and defense may demand potentially conflicting functional cell wall requirements, and thus modifications of the cell wall are tightly con...
