Arabidopsis BioCON evolutionary study:Arabidopsis thaliana, Bromus inermis phenotypic selection analysis

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）浓度升高的潜在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。本研究与珍妮弗·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，U of MN EEB）合作，结合传统定量遗传学方法与数量性状位点（QTL，quantitative trait locus）分析方法，旨在探明大气CO2浓度升高对以下三方面的影响：选择模式、选择响应，以及表型变异的遗传基础。
