Abstract

Recent studies with natural accessions of Arabidopsis thaliana have provided insights into the genetic variation underlying phenotypic differences in lab or common garden experiments. however, there has been essentially no information on phenotypic variation in natural settings. To address this lacuna, we have selected ca. 20 populations representing various types of habitats out of our recently identified sites near tubingen in germany (bomblies et al., plos genetics 2010) for monitoring. field phenotypic variations were directly measured from sets of individuals from these natural populations, and were contrasted with phenotypic data from progenies of those individuals in a common garden condition. We will present these phenotypic properties in the context of ecological responses to local environments and discuss plasticity and GxE interaction with comparison of field and common garden phenotypic measurements. Also we will address parent-progeny regression in a specific site to estimate the heritability in our phenotypic traits.
