Abstract:

Some species ofDyckiaSchult. f., includingDyckia brevifoliaBaker, are rheophytes that live in the fast-moving water currents of streams and rivers which are subject to frequent flooding, but also period of low water. This study aimed to analyze the leaf epidermis ofD. brevifoliain the context of epidermal adaptation to this aquatic plant’s rheophytic habitat. The epidermis is uniseriate, and the cuticle is thickened. The inner periclinal and anticlinal walls of the epidermal cells are thickened and lignified. Stomata are tetracytic, located in the depressions in relation to the surrounding epi

Abstract:

The leaf epidermis from a collection of 33 specimens encompassing most of the morphological variation of Festuca rubra in Eastern Canada and including two cytotypes (2n = 42 and 2n = 56) is described with 16 characters. The leaf epidermal composition differs markedly between culms and vegetative shoots. Many epidermal characters, particularly those from the vegetative shoots, are among the best ones for distinguishing between the two cytotypes. Parallel analyses using nine anatomical characters show the greater taxonomical potential of epidermis. Keywords: Festuca rubra, leaf, epidermis, anato

The leaf epidermal anatomy of 23 Crotalaria species was studied. The leaf epidermis was prepared by peeling and clearing methods and observed by a light microscope. The results of the leaf epidermis showed that the shape of an epidermal cell is polygonal, irregular or jigsaw-like and the anticlinal wall is straight, curved or undulated. There are two stomatal types: anomocytic and anisocytic, while the trichome is uniseriate. The papillae are presented in C. acicularis. The leaf epidermal anatomical characteristics cannot be used for species identification, however the shape and anticlinal wal

Salt increased the numbers of epidermal and palisade cells per unit area and the stomatal density of the abaxial epidermis but reduced the numbers of cells per leaf. Salt reduced stomatal indices of both epidermal surfaces, cell volumes, relative leaf expansion rate, leaf plastochron index, leaf fresh and dry weights, and specific leaf area.

This adaxialization is sometimes associated with abaxialization of the adaxial leaf regions, which constitutes a ‘switch’. Dosage analysis indicates Rld1 mutants are antimorphs.

Abstract As the outermost layer of plants, the epidermis serves as a critical interface between plants and the environment. During leaf development, the differentiation of specialized epidermal cell types, including stomatal guard cells, pavement cells, and trichomes, occurs simultaneously, each providing unique and pivotal functions for plant growth and survival. Decades of molecular-genetic and physiological studies have unraveled key players and hormone signaling specifying epidermal differentiation. However, most studies focus on only one cell type at a time, and how these distinct cell ty

Abstract:

Experiments were conducted on leaf laminae to determine the effects of intact, excised, and abraded epidermal layers on the success of graft unions in Catharanthus roseus and Sedum telephoides. Lamina surfaces grafted together within 2 – 4 weeks when the epidermis was removed from both graft partners. In contrast, the presence of epidermis on one or both graft partners prevented grafting. Intact epidermal cells adjacent to wounds did not divide or undergo other visible changes except for plasmolysis and death in a few grafting situations. Epidermal cells are developmentally distinctive from un

By means of light and scanning electron microscopy (SEM) the structure of leaf ’s epidermis of 8 species of genus Sedum L. was investigated. A number of common (amphistomatics, anisocytic type of stomatal complex, strum cuticle) and different signs have been revealed in the structure of the leaf ’s tissue. The results acquired on the basis of micromorphology of a leaf ’s epidermis can be used in the taxonomy of the investigated Sedum species.

In this study, the leaf epidermis of 28 samples representing six species of Nekemias and one species from the related genus of Ampelopsis are investigated using light microscopy. The results show that the shapes of leaf epidermal cells are polygonal or irregular. The variations of anticlinal walls are found commonly among species of Nekemia, especially within N. cantoniensis and N. grossede

Epidermal characters that can aid in the identification of the studied species are: the contour of the common cells on both leaf sur

Abstract:

The epidermis of Anemarrhena asphodeloides is composed of three distinct cell types: guard cells of the stomata, ordinary epidermal cells, and papilla cells occurring in files wedged between files of ordinary epidermal cells. Both stomata and papilla cells have their origin from formative mitoses in the young protoderm. Their differentiation described on the basis of light and polarization microscopy involves a decrease in cell contacts and changing orientation of cellulose microfibrils of the cell wall. These changes are discussed in relation to the pattern of cell divisions and to the modifi

WALH created feeding holes in the (lower) abaxial epidermis, with no visible exterior evidence of cell injury to the adaxial (upper) epidermis. Feeding holes were located in areas of the leaf with high stomatal density and were near stomata. Groups of cells in the palisade layers were empty or contained coagulated cell contents. Adjacent, apparently noninjured, palisade cells contained an abundance of starch granules,
