Sessile organisms such as plants have to develop adaptive responses to face environmental change. In Arabidopsis thaliana populations, natural variation for stress responses have been observed at different levels of integration and the genetic bases of those variations have been analysed using two strategies: classical linkage and association (LD) mapping. The strength of Arabidopsis resides in the huge amount of genomic data and molecular tools available leading to the identification of many polymorphisms responsible for phenotypic variation. Remaining limitations to clearly understand how Arabidopsis adapts to its environment, that is the complexity of the genetic architecture and the lack of ecological data, should be partially solved thanks to the development of new methods and the acquisition of new data.
固着生物（如植物）必须发展适应反应来应对环境变化。在拟南芥群体中，已经在不同的整合水平上观察到了对胁迫反应的自然变异，并且使用两种策略分析了这些变异的遗传基础：经典连锁和关联（LD）作图。拟南芥的优势在于可用的大量基因组数据和分子工具，这导致了许多负责表型变异的多态性的鉴定。要清楚地了解拟南芥如何适应其环境，即遗传结构的复杂性和缺乏生态数据，仍然存在一些限制，这需要借助新方法的发展和新数据的获取来部分解决。
