Poplars are challenged by a wide range of pathogens during their lifespan, and have an innate immunity system that activates defence responses to restrict pathogen growth. Large-scale expression studies of poplar–rust interactions have shown concerted transcriptional changes during defence responses, as in other plant pathosystems. Detailed analysis of expression profiles of metabolic pathways in these studies indicates that photosynthesis and respiration are also important components of the poplar response to rust infection. This is consistent with our current understanding of plant pathogen interactions as defence responses impose substantive demands for resources and energy that are met by reorganization of primary metabolism. This review applies the results of poplar transcriptome analyses to current research describing how plants divert energy from plant primary metabolism for resistance mechanisms.
