Periderm is a protective outer tissue formed during secondary growth in many seed plants, consisting of phellem, phellogen, and phelloderm. The phellem differentiates from phellogen and forms a barrier through lignin and suberin deposition. This structure is vital in protecting internal tissues from environmental stresses and in regenerating around wounds to prevent water loss and pathogen entry. Despite extensive studies on periderm formation, its underlying mechanisms remain largely unresolved. Additionally, the phellem of certain tree species, such as cork oak, has been utilized as a manufacturing material for centuries.
The periderm is a protective outer tissue in seed plants consisting of phellem, phellogen, and phelloderm, playing a key role in responding to environmental stresses.
Phellem, which differentiates from phellogen, establishes a barrier through lignin and suberin deposition, crucial for protecting against water loss and pathogens.
