Plant epithelia: What is the role of the mortar in the wall?
PLoS Biology, 2018 In a growing plant root, the inner vascular system is sealed off by an epithelium, the endodermis. The space between all of the cells in the endodermal layer is filled with an impermeable mass called the Casparian strip, which closes the spaces between ...

Plant biology: building barriers... in roots [PDF]
, 2017 The Casparian strip is an important barrier regulating water and nutrient uptake into root tissues. New research reveals two peptide signals and their co-receptors play critical roles patterning and maintaining barrier ...

Characterization of Oligopeptides in Solanum lycopersicum Xylem Exudates
Life, 2022 The xylem is the main pathway for the transport of water and molecules from roots to shoots. To date, it has been reported that secreted oligopeptides mediate root-to-shoot signaling, and some long-distance mobile oligopeptides have been detected in ...

Chemical components, physiological functions and regulation mechanism of plant Casparian strips [PDF]
SCIENTIA SINICA Vitae, 2020 Casparian strips are diagnostically modified structure mainly appeared in the endodermis, in which the radial parts of the cell walls are characterized by the deposition of lignin and suberin in the primary cell wall. As a barrier to the apoplastic movement of solutes from the cortex to the stele, Casparian strips are essential for the exclusion of ...

A Missing Link in Radial Ion Transport: Ion Transporters in the Endodermis
Frontiers in Plant Science, 2019 In higher plants, roots have important functions, such as the acquisition of water and ions, as well as transportation into the aerial parts of the plant via the xylem vessels.

Casparian strip diffusion barrier in Arabidopsis is made of a lignin polymer without suberin. [PDF]
Proc Natl Acad Sci U S A, 2012 Casparian strips are ring-like cell-wall modifications in the root endodermis of vascular plants. Their presence generates a paracellular barrier, analogous to animal tight junctions, that is thought to be crucial for selective nutrient uptake, exclusion of pathogens, and many other processes. Despite their importance, the chemical
