A Comparative Analysis of Quantitative Metrics of Root Architecture

Figure 2

Cluster heat map of phenotypic traits. Hierarchical clustering of a few phenotypes was generated using Spearman correlation of max-min scaled phene values of bean phenotypes at 40 days (a). The color scale indicates the magnitude of the trait values (blue, low value; red, high value). The numbers indicated on the heat map refer to the phenotype in the specific row of the heat map. The corresponding phenotypes are visualized in (b). Primary roots are in black; basal roots are in red; hypocotyl-borne roots are in green. #: number of axial roots; Axial.Diam: axial root diameter; LRBD: lateral root branching density; Lat.Length: lateral root length; Lat.Diam: lateral root diameter; BW1: basal roots at whorl 1; BW2: basal roots at whorl 2; BW3: basal roots at whorl 3; BW4: basal roots at whorl 4; BW5: basal roots at whorl 5; HBR: hypocotyl-borne roots; PR: primary root.
