Themes and variations in cell type patterning in the plant epidermis
Current Opinion in Genetics & Development, 2015It has recently become evident that plant development, like animal development, has molecular patterning modules that are reused again and again to create different cell type patterns. Here we focus on three of these plant modules: (1) the MYB-bHLH-WD40 protein complex, (2) the transmembrane calpain protease DEFECTIVE KERNEL1 (DEK1), and (3 ...

Petunia Peroxidase a is Localized in the Epidermis of Aerial Plant Organs
Journal of Plant Physiology, 1990Summary The distribution of soluble peroxidase activity in tissues from petals, leaves and stems of petunia ( Petunia hybrida ) was investigated. In petals, the upper epidermis contained nearly 20 % of the soluble peroxidase activity, but no peroxidase activity was recovered from protoplasts isolated from this tissue.

The discrete root epidermis of floating plants
New Phytologist, 1990summaryThe reason why roots of some floating plants have a discrete epidermal meristem was investigated by comparing rates of anticlinal and periclinal division in shells of tissue during early development of lateral primordia of Pistia stratiotes L., which has such an epidermis, with those of Eichhornia crassipes (C. F. P.

Cell shapes and patterns as quantitative indicators of tissue stress in the plant epidermis
Soft Matter, 2015In a confluent, single-cell tissue layer, we show that cell shapes and statistics correlate directly with the tissue's mechanical properties, described by an energy functional with generic interfacial terms only. Upon increasing the cohesive component of the model, we observe a clear transition from a tense state with isotropic cells to a relaxed state

SPECIFICITY TO PENETRATION OF THE EPIDERMIS OF A PLANT BY THE HYPHAE OF A PATHOGENIC FUNGUS
American Journal of Botany, 1932Specificity to attack by disease-inducing organisms has long been accepted as fact, and because of this acceptance little experimental work has been done on the problem. On the other hand, a vast amount of work has been done on the questions of immunity, resistance, and susceptibility.

Journal of Plant Physiology & Pathology, 2018
Objective: The main objectives of the present work were: 1) to securely identify the fleshy fruits of a relevant number of species of toxic vascular plants by their epicarp features; 2) to draw attention to the potential of fruit micromorphology in the identification of poisonous plants and in plant taxonomy.

Plant epidermis‐derived secretory structures: from glandular trichomes to secretory cavities
New PhytologistSummary Trichomes develop as outward projections from the epidermal surface. By contrast, as subepidermal secretory cavities, citrus oil glands originate from epidermal cells and develop into specialized hollow structures. During the development of these epidermis‐derived structures in vascular plants, transcription factors, such as ...
