Elevated Ozone Concentration and Nitrogen Addition Increase Poplar Rust Severity by Shifting the Phyllosphere Microbial Community.

ABSTRACT: Tropospheric ozone and nitrogen deposition are two major environmental pollutants. A great deal of research has focused on the negative impacts of elevated O₃ and the complementary effect of soil N addition on the physiological properties of trees. However, it has been overlooked how elevated O₃ and N addition affect tree immunity in face of pathogen infection, as well as of the important roles of phyllosphere microbiome community in host-pathogen-environment interplay. Here, we examined the effects of elevated O₃ and soil N addition on poplar leaf rust [Melampsora larici-populina] severity of two susceptible hybrid poplars [clone '107': Populus euramericana cv. '74/76'; clone '546': P. deltoides Í P. cathayana] in Free-Air-Contr
