Fig.4. Coordination in trait modification in leaf vein density, specific root length (SRL) and root diameter across seed plants. Points represent reconstructed node values for each trait along the phylogeny based on extant species. Colors represent main clades within seed plants. Panels A), C) and D) represent the reconstructed changes across time (MYA) in RTD, SL and Diameter respectively, with the insert in panel C) representing the reconstructed changes for leaf vein density as a comparison. Panels B), D) and F) represent the correlation between leaf venation and root traits from shared nodes between phylogenetic trees after phylogenetic reconstruction.
