Microorganisms living within plants play crucial roles in their health and function, yet these diverse communities that make up the plant microbiome remain poorly understood. The dune grass Ammophila breviligulata. is an ecosystem engineer which helps to build and stabilize dune ecosystems effectively acting as a buffer against storms to coastal communities. It is currently unknown whether the Ammophila microbiome plays a role in this plant species’ ability to transform dune ecosystems.. In this study, we assessed fungal diversity of endophytes—microbes living within plant tissues— in Ammophila leaves collected from Leelanau State Park, MI along the eastern shores of Lake …

Understanding how pathogens evolve in response to changes in their host is paramount to combating the spread of emergent strains of disease. This is particularly true for plant pathogens that cause billions of dollars of damages to crops globally, every year. Understanding the molecular interactions between pathogens and their hosts therefore sheds light on the coevolutionary arms race that can result in host-specificity and host-shifts in plant pathogens. This research approaches the question of how fungal pathogens interact with their plant hosts utilizing both unique and shared arsenals of secreted proteins (SPs) during infection, and addresses the question of whether …
Environmental Factors, Not Plants, Contribute To Functional Diversity Of Soil Bacteria In The Dunes Of Lake Michigan., Andrea Stark Howes
Environmental Factors, Not Plants, Contribute To Functional Diversity Of Soil Bacteria In The Dunes Of Lake Michigan., Andrea Stark Howes

Soil bacteria play important roles in nutrient cycling and other ecosystem functions, and many biotic and abiotic factors can influence bacterial functional diversity. The goal of this field study was to examine differences among bacterial communities in sand dunes of Lake Michigan. I used Biolog Ecoplates™ to compare bacteria functional diversity associated with four different plant species: the native dune-building grass Ammophila breviligulata, invasive species Leymus arenarius and Gypsophila paniculata, and native legume Lathyrus japonicus across 13 sites in Michigan, representing a gradient in abiotic factors such as precipitation and temperature. I found no differences in bacterial function associated with …
