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.
根系结构（RSA）受植物激素生长素的调控，使植物在特定环境中具有适应性优势。Waidmann 等人和 Ogura 等人最近利用具有地理代表性的拟南芥（Arabidopsis thaliana）品系作为 GWAS 图谱绘制的资源，鉴定出两个参与调节生长素介导的 RSA 并赋予植物在特定生境中适应能力的新成分。
