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

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.

The Making of Plant Armor: The Periderm

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.

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 ...

Periderm in Ophioglossaceae

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.

Tissue-Specific Transcriptomes Reveal Gene Expression Trajectories in Two Maturing Skin Epithelial Layers in Zebrafish Embryos [PDF]

G3: Genes, Genomes, Genetics, 2019
Epithelial cells are the building blocks of many organs, including skin. The vertebrate skin initially consists of two epithelial layers, the outer periderm and inner basal cell layers, which have distinct properties, functions, and fates.

Epithelial Migration and Non-adhesive Periderm Are Required for Digit Separation during Mammalian Development [PDF]

Developmental Cell, 2020
The fusion of digits or toes, syndactyly, can be part of complex syndromes, including van der Woude syndrome. A subset of van der Woude cases is caused by dominant-negative mutations in the epithelial transcription factor Grainyhead like-3 (GRHL3), and ...

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

Periderm fate and independence of tooth formation are conserved across osteichthyans [PDF]

EvoDevo
Background Previous studies have reported that periderm (the outer ectodermal layer) in zebrafish partially expands into the mouth and pharyngeal pouches, but does not reach the medial endoderm, where the pharyngeal teeth develop.

Variations in genotype- and position-dependent seed tuber sprouting linked to skin morphology in white Guinea yam [PDF]

Scientific Reports
White Guinea yam (Dioscorea rotundata) is a staple tuber crop in West Africa; however, its vegetative propagation is constrained by irregular dormancy and unpredictable sprouting, which reduce planting efficiency and yield stability.

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.
