Significance of the exodermis in root function

1989
An exodermis is a specialized type of hypodermis which often occurs in roots. The hypodermis, like the endodermis, is part of the cortex since it is derived from the ground meristem. The hypodermis and endodermis form the outer and inner boundaries of the cortex, respectively.

Variabilita reakce exodermis na nedostatek živin v prostředí

2023
v angličtině Plant growth and development is largely dependent on the soil environment which is a source of minerals and water needed for plants to survive. However, the availability of these resources in the soil is very heterogenous and important elements can be leached into the lower parts of the soil or bound to soil particles.

Infection of barley roots by Chaetomium globosum: evidence for a protective role of the exodermis

Mycological Research, 2003
Plant pathogenesis by fungi is known to be dependent on the host genotype, the virulence of the pathogen and certain environmental conditions influencing fungal establishment. Previously, it has been shown that Chaetomium globosum, a fungus well-characterized for its biocontrol potential, causes necrosis on barley roots grown in Murashige and Skoog (MS)

Mechanismy reakce exodermis na dostupnost živin v prostředí

2021
in English The apoplastic barriers of the root (endodermis and exodermis) represent an important regulatory mechanism for the uptake of water and nutrients from the environment, ensuring its selectivity. In addition, both layers respond to stress factors by altering its rate and degree of cell wall modification, which affects the transport properties ...

The Effect of Lateral Root Outgrowth on the Structure and Permeability of the Onion Root Exodermis

Botanica Acta, 1993
AbstractLateral root development in onion is accompanied by a variety of anatomical and permeability changes in some cells of the adventitious root. The endodermal Casparian band of the parent root is disrupted early in the development of the lateral but later extends so as to be continuous with the developing Casparian band of the new root.

Salinity accelerates endodermal development and induces an exodermis in cotton seedling roots

Environmental and Experimental Botany, 1995
The development of the endodermis was studied in 5- to 48-day-old cotton (Gossypium hirsutum L., cv. Acala SJ-2) seedling roots grown in vermiculite at different NaCl salinity levels. Sensitive fluorochromes (berberine-aniline blue for Casparian bands, and fluorol yellow-aniline blue for suberin lamellae) were used to detect cell wall modifications ...

Development of cell wall modifications in the endodermis and exodermis of Allium cepa roots

Canadian Journal of Botany, 2001
The cytological events of wall modification in the endodermis and exodermis of Allium cepa L. roots were examined with fluorescence and transmission electron microscopy. In the endodermis, Casparian bands, suberin lamellae, and tertiary walls developed in succession.

Suberin deposition and band plasmolysis in the corn (Zea maysL.) root exodermis

Canadian Journal of Botany, 1997
The exodermal Casparian band in corn (Zea mays L.) was first seen 10 mm distal to the kernel 4 days after planting. From its inception, the band usually occupied most of the radial wall (as seen in a cross section of the root). Subsequent maturation of the band around the root was asynchronous into the region of emerging lateral roots.

Characteristics of Arbuscular Mycorrhizal Fungal Infection in Dimorphic Exodermis of Feeder Roots in Asparagus Seedlings.

Engei Gakkai zasshi, 1999
The characteristics of infection of five arbuscular mycorrhizal fungi in the dimorphic exodermis consisting of short and long cells in feeder roots of asparagus [Asparagus officinalis L., cv. MW500W and Welcome] seedlings were investigated. Eight weeks after inoculation with the five fungal species, infection and symbiosis were detected in both ...

Diferenciace exodermis v podmínkách nedostatku živin, vliv fytohormonů.

2018
Apoplastic barriers (exodermis and endodermis) control free movement of substances by apoplast, which is achieved by specific cell wall modifications. Differentiation of these barriers is to some extent variable. It has been demonstrated many times that the differentiation of root apoplastic barriers is strongly influenced by unfavourable environmental
