Environment- and genotype-dependent growth investment into main root and lateral roots. LRS profiles (A) and average RSA reconstruction (B) of Arabidopsis accessions grown in control, low K, low P, and combined low P and low K (low PK) media. Vertical lines represent the mean main root path length. The main root path was divided into four equally sized sections and lengths of laterals were added within each section. The width of each square represents the mean LRS of three to six replicate plants.
