Abstract:
The cellulose-binding domains (CBDs) in the Phytophthora cellulose-binding elicitor lectin (CBEL) are potent elicitors of plant defence responses. Induction of defence has also been reported in various cellulose-deficient mutants of Arabidopsis thaliana. Based on these observations, we propose a model linking cellulose alteration to defence induction. This integrates the fast increase in cytosolic calcium recorded in response to CBEL, mechano-stimulated calcium uptake mechanisms, and proteins that interact functionally with the cellulose synthase complex. In this context, CBDs emerge as new tools to decipher the signalling cascades that result from cell wall-cellulose perturbations.
