The epidermis both drives and restricts plant shoot growth
Nature, 2007The size of an organism is genetically determined, yet how a plant or animal achieves its final size is largely unknown. The shoot of higher plants has a simple conserved body plan based on three major tissue systems: the epidermal (L1), sub-epidermal (L2) and inner ground and vascular (L3) tissues.

Modeling the nonlinear elastic behavior of plant epidermis
Botany, 2020Cell growth and organ development in plants are often correlated with the tensile behavior of the primary cell wall. To understand the mechanical behavior of plant material, various mechanical testing techniques have been employed, such as tensile testing of excised tissue samples. The onion (Allium cepa L.) epidermis has emerged as a model system for

A Technique for measuring Structural Features of Plant Epidermis using Cellulose Acetate Films
Nature, 1956IT is often difficult to peel off areas of plant epidermis which are large enough for accurate determinations of mean cell size and stomatal distribution. Buscalioni and Pollacci1, and Long and Clements2 have described a method for counting stomata using collodion films; but these were found to be sometimes difficult to remove from a treated leaf, and ...

Plant Surface Lipids and Epidermis Development
2016The epidermis has a strategic position at the interface between the plant and the environment. In order to control exchanges with the environment as well as to protect the plant from external threats, the epidermis synthesises and secretes surface lipids to form a continuous, transparent and hydrophobic layer known as the cuticle.

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 ...

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.

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.

A Gravitational Model for Plant Classification Using Adaxial Epidermis Texture
2015The leaves are very informative plant organs. They are extensively used in plant anatomical studies focusing taxonomy. Their both inner and outer structures provide very discriminant features from vegetal species. In this study, we propose using images from adaxial epidermis for plant classification. The adaxial epidermis is a very variable region in a

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
