Identifying the genes important in plant ecology and evolution
Our work focuses on the ecology and evolution of plants. We are especially interested in finding the genes that are important in ecologically relevant plant traits.
Because they are fixed in place, plants are much more likely to adapt to local environmental conditions than other organisms. However, it remains unclear how plants simultaneously adapt to both abiotic and biotic stresses. Which genes are involved? Does pleiotropy play a role? Plants, like other higher organisms, are colonized by a wide variety of microbes (e.g. viruses, bacteria, fungi), and the genes within the microbiome often outnumber those in the host. Do the genes within the microbiome also shape plant adaptation?
Our studies use tools from population genetics, molecular genetics, statistics and ecology to investigate how the plant-microbiome forms and whether the structure of the microbiome shapes host phenotypic variation.
