Cutin and suberin are hydrophobic lipid biopolyester components of the cell walls of specialized plant tissue and cell-types, where they facilitate adaptation to terrestrial habitats. Many steps in their biosynthetic pathways have been characterized, but the basis of their spatial deposition and precursor trafficking is not well understood. Members of the GDSL lipase/esterase family catalyze cutin polymerization, and candidate proteins have been proposed to mediate interactions between cutin or suberin and other wall components. Comparative genomic studies of charophyte algae and early diverging land plants, combined with knowledge of the biosynthesis, trafficking and assembly mechanisms, suggests an origin for the capacity to secrete waxes, as well as aliphatic and phenolic compounds before the first colonization of true terrestrial habitats.
