One of the mysteries of the English language finally explained.
An inert impermeable waxy substance present in the cell walls of corky tissues.
- ‘Chemically, apoplastic barriers of roots are depositions of the biopolymers lignin and suberin within the cell wall matrix, which may occlude wall pores previously filled with water.’
- ‘Peroxidase is probably implicated in lignin and/or suberin formation during the polymerization of monoglinols or aromatic monomers.’
- ‘Peroxidases are present in the crease tissue at this time and it has been suggested that they may have a role in the formation of lignin / suberin in the chalazal cell walls.’
- ‘Cytochemistry and autofluorescence observations were used to detect the presence of lignin and suberin in unfixed tissues.’
- ‘Histochemical staining showed lignin and suberin to be absent in both untreated and oleocellosis-damaged tissue.’
Mid 19th century: from Latin suber ‘cork’ + -in.
