One of biology's major goals is to describe understand adaptive evolution on multiple levels of organization: from the genes and mutations involved, to their effects on gene expression and phenotypes, to how those traits function in a realistic ecological context. One area to address this challenge is in the life history and developmental transition from vegetative growth to flowering, which is often under geographically variable selection due to climatic variation and seasonality. We have investigated this in the annual plant, Arabidopsis thaliana, which in addition to being the pre-eminent model system for plant biology, genomics, and genetics, is also in the same family as the important crop, Canola. The genetic and genomic resources for Arabidopsis are being increasingly leveraged for studies in the ecology, evolution, and genetics of adaptation.

生物学的主要目标之一是描述对组织多个层面的适应性进化的理解：从所涉及的基因和突变，到它们对基因表达和表型的影响，再到这些特征如何在现实的生态环境中发挥作用。应对这一挑战的一个领域是生命史和从营养生长到开花的发育过渡，由于气候变化和季节性，这往往受到地理可变选择的影响。我们在一年生植物拟南芥中对此进行了研究，它不仅是植物生物学、基因组学和遗传学的杰出模型系统，而且与重要作物双低油菜籽属于同一家族。拟南芥的遗传和基因组资源越来越多地用于生态学、进化和适应遗传学的研究。
