The ongoing and magnifying consequences of environmental change present a complex challenge for plants. One potential mechanism by which plants may promote long-term stress tolerance is through selection of beneficial members of the seed microbiome. However, the functions and persistence of many members of the seed microbiome are not known, and even less is understood about their roles in determining plant stress tolerance. In this project, we will use common bean (Phaseolus vulgaris L.) as a model to investigate changes in the seed microbiome that occur as a result of two stressors: drought and nutrient excess. We have taken an approach that leverages high-throughput sequencing (of both the microbiome and the plant epigenome) and metabolomics with controlled experiments to decipher the mechanistic relationships between the plant and its seed microbiome during stress.
