The Making of Plant Armor: The Periderm [PDF]

Annual Review of Plant Biology, 2022
The periderm acts as armor protecting the plant's inner tissues from biotic and abiotic stress. It forms during the radial thickening of plant organs such as stems and roots and replaces the function of primary protective tissues such as the epidermis and the endodermis. A wound periderm also forms to heal and protect injured tissues.

Periderm in Ophioglossaceae [PDF]

Acta Societatis Botanicorum Poloniae, 2015
This paper describes the occurrence of periderm in three genera, Botrychium Swartz., Helminthostachys Kaulfuss, and Ophioglossum Linn. under field conditions. Not all plants of an area belonging to the same or different species possess it.

Potato Periderm Development and Tuber Skin Quality

Plants, 2022
The periderm is a corky tissue that replaces the epidermis when the latter is damaged, and is critical for preventing pathogen invasion and water loss. The periderm is formed through the meristematic activity of phellogen cells (cork cambium). The potato

Dynamic Field Assessment of Canopy Development and Periderm Maturation in Potato (Solanum tuberosum L.) [PDF]

Plants
Background: Periderm development in potato (Solanum tuberosum L.) is critical for protecting tubers from biotic and abiotic stress, yet the relationship between periderm maturation, canopy development, and tuber growth during the active growing season ...

Pinus pinea L. Periderm as a Sustainable Source of Phenolic Bioactives: Integrated Phytochemical, Antioxidant, and Elemental Investigation. [PDF]

Chem Biodivers
A hydroalcoholic extract from the renewable periderm of Pinus pinea is characterized through integrated phytochemical, biological and elemental analyses. The extract exhibits a phenolic‐rich composition, significant antioxidant activity and preliminary protection against oxidative stress in SH‐SY5Y cells, while elemental profiling indicates low levels ...

Cross-stage single-cell and spatial metabolome analyses reveal periderm specialization and tanshinone biosynthesis in Salvia miltiorrhiza roots. [PDF]

New Phytol
Biosynthesis and accumulation of tanshinones in the periderm of Salvia miltiorrhiza during secondary root growth. Summary Perennial herbs develop long‐lived roots that undergo repeated cycles of secondary growth, during which the periderm functions as a protective barrier and a major site of specialized metabolite accumulation.

A novel, PCP-dependent tissue organising principle coordinating morphogenesis between embryonic skin epidermal layers. [PDF]

J Anat
‘Outside‐in’ expression of Fz6 across multiple layers of mouse embryo epidermis is connected to Fz6 asymmetry in the basal layer plane. Fz6 loss‐of‐function correlated with failure to: coordinate axial bias of cell long axis orientation across epidermal layers, switch axial cell long axis orientation during suprabasal layer development and establish ...

The preprophase band is dispensable for robust cell division orientation in wood-forming cambium stem cells. [PDF]

New Phytol
Characterization of periclinal and anticlinal cell divisions in dividing cambium stem cells (CSCs). (a) Scheme indicating periclinal and anticlinal cell divisions in CSCs in the Arabidopsis hypocotyl. The orange dashed ring in the middle panel represents the cambium area. The orange cuboids represent individual CSCs.

PAT (Periderm Assessment Toolkit): A Quantitative and Large-Scale Screening Method for Periderm Measurements

Plant Phenomics
The periderm is a vital protective tissue found in the roots, stems, and woody elements of diverse plant species. It plays an important function in these plants by assuming the role of the epidermis as the outermost layer.

A molecular framework to study periderm formation in Arabidopsis [PDF]

New Phytologist, 2018
Summary During secondary growth in most eudicots and gymnosperms, the periderm replaces the epidermis as the frontier tissue protecting the vasculature from biotic and abiotic stresses. Despite its importance, the mechanisms underlying periderm establishment and formation are largely unknown.
