Arabidopsis Phenologyunder: Arabidopsis BioCON evolutionary study

We know a lot about the potential ecological effects of increasing concentrations to atmospheric CO2; however, we know relatively little about whether increased concentrations will also affect evolution. In collaboration with Jennifer Lau (KBS and Michigan State University), Peter Reich (U of MN Forestry) and Ruth Shaw (U of MN EEB) we are using a combination traditional quantitative genetic and QTL approaches to determine the effect elevated CO2 has on; patterns of selection, responses to selection, and the genetic basis of phenotypic variation.目前学界已对大气二氧化碳（CO₂）浓度升高所可能带来的生态效应形成了较为充分的认知，但对于该浓度升高是否同样会影响生物演化，我们的了解仍相对有限。本研究与詹妮弗·劳（Jennifer Lau，KBS与密歇根州立大学）、彼得·赖希（Peter Reich，明尼苏达大学林学院）以及露丝·肖（Ruth Shaw，明尼苏达大学生态、进化与行为系（EEB））合作，采用传统数量遗传学与数量性状位点（Quantitative Trait Locus, QTL）相结合的研究方法，旨在明确升高的CO₂对以下方面的影响：选择模式、对选择的响应，以及表型变异的遗传基础。
