We are initiating studies using the rock cress plant, Arabidopsis lyrata, as a model organism to understand resource allocation between growth and maintenance vs. current reproductive output. We choose A. lyrata because it is a sister of the well-studied model plant A. thaliana, and its genome is being sequenced. Moreover, unlike A. thaliana, A. lyrata is a perennial with extensive variation in resource allocation strategies. Our goal is to construct models for how different genetic mechanisms affect growth and reproductive traits and how genetic variation in these mechanisms would result in different resource allocation strategies through their effects on networks of traits. We are further interested in predicting how these strategies affect fitness in different environments. We will compare trait correlations predicted by our models to those from our field and growth chamber studies using A. lyrata plants from four North American and European populations. The eventual goal is to predict the functions of genes that underlie variation in the trait networks.
