Root system architecture (RSA), governed by the phytohormone auxin, endows plants with an adaptive advantage in particular environments. Using geographically representative arabidopsis (Arabidopsis thaliana) accessions as a resource for GWA mapping, Waidmann et al. and Ogura et al. recently identified two novel components involved in modulating auxin-mediated RSA and conferring plant fitness in particular habitats.

适应性增长：塑造生长素介导的根系统架构。

由植物激素生长素控制的根系体系结构（RSA）使植物在特定环境中具有适应性优势。使用具有地理代表性的拟南芥（Arabidopsis thaliana）种质作为GWA作图的资源，Waidmann等人。和小仓等。最近，他们发现了两个新的成分，它们参与调节植物生长素介导的RSA，并在特定的生境中赋予植物适应性。
