The Casparian strip in pea epicotyls: Effects of light on its development
Planta, 1994The Casparian strip, which is specific to roots, was studied in the epicotyls of dark-grown seedlings of pea (Pisum sativum L.) where it was found to have the same morphology and properties as the strip in roots. In dark-grown seedlings, the distance between the upper-most position of the Casparian strip and the bending point of the hook (about 37 mm ...

Development of the Casparian strip in primary roots of maize under salt stress
Planta, 2004The Casparian strip in the endodermis of vascular plant roots appears to play an important role in preventing the influx of salts into the stele through the apoplast under salt stress. The effects of salinity on the development and morphology of the Casparian strip in primary roots of maize ( Zea mays L.) were studied.

Lignin developmental patterns and Casparian strip as apoplastic barriers: A review
International Journal of Biological MacromoleculesLignin and Casparian strips are two essential components of plant cells that play critical roles in plant development regulate nutrients and water across the plants cell. Recent studies have extensively investigated lignin diversity and Casparian strip formation, providing valuable insights into plant physiology.

ON THE FUNCTION OF THE CASPARIAN STRIPS IN ROOTS
Acta Botanica Neerlandica, 1974SUMMARY The dyes safranin and basic fuchsine as well as ferric salts enter the stele when applied as dilute solutions to intact root parts where Casparian strips are well developed. As the entrance is not hampered when the protoplasm has been killed or its activity and permeability diminished by low temperature the most likely way of entrance is ...

Observations on the Phi-Thickenings and Casparian Strips in Pelargonium Roots
American Journal of Botany, 1976An ultrastructural examination of hypodermal cell walls failed to demonstrate the presence of casparian strips as has been reported in the literature. Rather, these cells have supportive phi‐thickenings which differ significantly from casparian strips. Adjacent phi‐thickenings are convex‐convex and stratified in transection, with an uneven surface like

The Casparian Strip as a Barrier to the Movement of Lanthanum in Corn Roots
Science, 1974The effectiveness of the Casparian strip as a barrier to apoplastic movement of solutes from cortex to stele of corn roots was investigated by using lanthanum in combination with electron microscopy. Lanthanum deposits were found only in cell walls and on the outside of the plasma membrane of epidermal, cortical, and endodermal cells up to the ...

Effects of brefeldin A on the development of the Casparian strip in pea epicotyls
Protoplasma, 1998The Casparian strip, a structure that is present in roots, is also present in epicotyls of dark-grown pea seedlings. In a dark-grown epicotyl, the cells in each stage of the development of the Casparian strip have been suggested to be lined up basipetally in the region 3 to 37 mm below the bending point of the hook, in order of the developmental stage.

Development of the Casparian strip is delayed by blue light in pea stems
Planta, 2011To understand the regulatory mechanisms involved in tissue development by light, the kinetics of regulation of Casparian strip (CS) development in garden pea stems was studied. We found that short-term irradiation with white light delayed the development of the CS and used this delay to assess the quantitative effect of light on CS development.

Radial widening of the Casparian strip follows induced radial expansion of endodermal cells
Planta, 2001The Casparian strip, the barrier to apoplastic transport that is located at the endodermis in roots and stems, is formed by individual endodermal cells and is constructed as a highly organized mesh within the primary wall. Since little is known about the mechanism of formation of the strip, we tried to obtain morphological evidence for the existence ...

Casparian strips in needles of Pinus bungeana: isolation and chemical characterization
Physiologia Plantarum, 2003By using cell wall degrading enzymes, Casparian strips were for the first time isolated from Pinus bungeana needle endodermis. They appeared as a fine network, similar to those isolated from roots. Fourier transform infrared spectroscopic analysis provided evidence that the Casparian strips were impregnated with lignin, suberin, cellulose and cell wall
