Figure 1 Overview of the evolution of plant adaptations to dry
environments. The recurring appearance of carbon concentrating
mechanisms (CCMs), desiccation tolerance (DT) and root impermeability in
Viridiplante lineages are shown. Root impermeability shows endodermis
(yellow), exodermis with suberin only (bright turquoise) and exodermis
with suberin and lignin (blue).
Figure 2 Exodermis (hypodermis) evolution across land plants.
The inner ring represents the exodermis phenotype and the outer ring the
major clades. The phylogenetic tree was generated using NCBI Common Tree
(www.ncbi.nlm.nih.gov/Taxonomy/CommonTree/wwwcmt.cgi)
and edited using iTOL
