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.
杨属在其一生中受到多种病原体的挑战，具有先天免疫系统，可激活防御反应以限制病原体的生长。杨属 - 锈菌互作的大规模表达研究表明，在防御反应中会发生协同的转录变化，就像在其他植物病理系统中一样。这些研究中对代谢途径表达谱的详细分析表明，光合作用和呼吸作用也是杨树对锈菌感染反应的重要组成部分。这与我们目前对植物病原体相互作用的理解是一致的，因为防御反应对资源和能量提出了实质性的要求，这些要求通过对初级代谢的重新组织来满足。本综述将杨树转录组分析的结果应用于当前的研究，描述了植物如何将能量从植物初级代谢中转移出来用于抵抗机制。
