Summary

Plant-Microbe Interfaces. The Populus-microbiome interface encompasses diverse biological components and physical and temporal scales that result in dynamic functional processes. Events at the molecular and cellular levels lead to specific, mutualistic host-microbe selection and impact host performance and community formation. Furthermore, the structure of the microbial community depends on specific and nonspecific relationships that vary based on the physical location and dynamic chemical environment defined by the host. These molecular- and cellular-level events can vary over the lifetime of the host and respond to changes in the environment. [Courtesy Oak Ridge National Laboratory]
