| Outline of Final Research Achievements |
Naturally occurring free N-glycans (FNGs) derived from glycoproteins/glycopeptides by the action of peptide: N-glycanase (PNGase) and endo-β-N-acetylglucosaminidase (ENGase) have been postulated to act as signaling molecules stimulating plant growth or fruit ripening. To elucidate the physiological role of FNGs in plants, we have analyzed the sensitivity of the A.thaliana mutants, ENGase-DKO and acidic PNGase-DKO, to abiotic (NaCl treatment) and biotic (P. syringae infection) stresses. Since it is believed that nucleocytoplasmic lectins function in the plant stress response, synthesized glycopolymers were used to study the interaction between FNGs and lectins in plant cells.
