The paper examines metabolic diversity in Arabidopsis thaliana using metabolomics and GWA mapping, finding that local adaptation and selection shape secondary metabolite profiles through haplotype variation.

The paper introduces PCgen, an algorithm that reconstructs genetic networks by incorporating direct and indirect effects, improving accuracy using individual data over genotypic means.

This study uses cybrids to show that plasmotype variation affects plant phenotypes through additive and epistatic interactions, with epistasis explaining more variance than additivity.
