I am interested to learn about other elicitors than chitosan which can be used to induce responses like upon pathogen infection in the moss Physcomitrella patens. Thanks a lot for your suggestions!
Very interesting question and a good project. Unfortunately I have no convincing idea. I hope others have those. Chitosan is a very simple-looking substance (on paper). In reality, it is imbedded in a lot of protein stuff. So it is not easy to ascribe any effect unequivocally to chitosan itself, as soon as you start to work with chitosan from fungi and not with the normal but unphysiological deacetylated crab-shell chitin. I am interested to learn what you find out. Good luck!
You should try Moringa Extract................Search for it... I hope it will work out. Its not a chemical but it contains many things.

Dear all,
thanks a lot for your contributions on this subject! I am specifically looking for commercial available chemicals (for batch to batch reproducibility) as we don't want to do any infections or treatments with extracts. Thanks a lot for any suggestions on that!
Chitin oligomers, if you can find them (japanese chemical companies?), elicit different phenotypic response than chitosan. Beta 1->3 glucan (Laminarin, sigma L9634) might be worth trying.
