Yes, PR-protein expression can be induced in transgenic plants under abiotic conditions. Please see the paper: The family 10 of plant pathogenesis-related proteins: Their structure, regulation, and function in response to biotic and abiotic stresses. 2006. Liu, J.-J.; Ekramoddoullah, A.K.M. Physiological and Molecular Plant Pathology 68: 3-13. It may help you.

thanks Aicha, but what about chitinase?

Ahmed Mansour Alzohairy

The answer is yes again, for instance the over expression of heat shock proteins was observed in the Microarray data of fungal infection and mechanical shearing. Likewise, I can expect to see over expression of drought resistance genes could during nematode infection if the signaling of both pathways are interlinked.
