Cell biology: Zipping the Casparian strip
Nature Plants, 2016Roots must sort the good from the bad and distinguish the inside from the outside. In endodermal cells, a ring-like apoplastic diffusion barrier called the Casparian strip is established, splitting the cells down the middle into inner and outer lateral halves. Its integrity and polarity depends on a novel protein kinase called SCHENGEN1.

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

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 ...

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

Transient cell-specific EXO70A1 activity in the CASP domain and Casparian strip localization
Nature Plants, 2017In a striking case of evolutionary convergence, polarized cell layers with ring-like diffusion barriers have evolved in both plant and animal lineages independently. In plants, ring-like Casparian strips become localized by the CASPARIAN STRIP MEMBRANE DOMAIN PROTEINS (CASPs). The mechanism of this striking localization, however, has remained enigmatic.

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 ...

The Casparian strip, a barrier to the apoplastic movement of solutes from the cortex to the stele, is essential for the exclusion of salts, selective nutrient uptake, and many other processes. To date, extensive studies have focused on the physiological functions of endodermal Casparian strips.
