Precipitation patterns in the Midwest are becoming more extreme due to climate change. Spring floods and summer droughts are predicted to increase in frequency. This rapid change in precipitation may challenge plant growth throughout the region. We simulated the effects of these extremes in precipitation on 100 Arabidopsis thaliana recombinant inbred lines (RIL) to investigate gene-by-environment interactions on five growth and development phenotypes. We calculated the genetic variance, correlation, and heritability of the phenotypes, and will perform a QTL analysis to determine candidate genes that may play a role in plant success in this environment. The long-term goal of the project is to identify genes with an effect on plant fitness in the Midwestern environment as it is impacted by climate change.
