The Role of Peptidyl-Prolyl cis/trans Isomerase Genes of Arabidopsis thaliana in Plant Defense during the Course of Xanthomonas campestris Infection

Experimental data obtained in this study had shown the involvement of A. thaliana immunophilin genes At2g16600, At4g33060, and At5g48570 in plant defense responses to the Xanthomonas campestris invasion. We had found not only that the expression levels of these genes changed upon bacterial infection, but also that the plant's resistance to the pathogen was increased if the expression levels of the immunophilin genes were elevated in the host cells.
