Exodermis and Endodermis Respond to Nutrient Deficiency in Nutrient-Specific and Localized Manner [PDF]

Plants, 2020
The exodermis is a common apoplastic barrier of the outer root cortex, with high environmentally-driven plasticity and a protective function. This study focused on the trade-off between the protective advantages provided by the exodermis and its ...

Root tip excision-induced exodermis lignification impacts lateral root emergence in Brachypodium distachyon. [PDF]

New Phytol
Summary The mechanisms controlling lateral root emergence in monocots, particularly the role of the exodermis, are poorly understood. We investigated how natural variation in the Brachypodium distachyon stress response shapes root system architecture by modulating cell wall dynamics.

Sclerified Cork Outperforms the Exodermis: Root Water Permeability Decreases in the Soil-To-Canopy Transition of the Aroid Vine Epipremnum aureum. [PDF]

Physiol Plant
ABSTRACT The aroid vine Epipremnum aureum undergoes changes in habitat and growth axis direction from terrestrial (plagiotropic) to canopy (orthotropic) conditions. Since aerial roots connected to the forest soil are vital for water and nutrient uptake in these vines, we hypothesize that morphophysiological acclimation occurs, enabling root survival ...

Coordination of cortex modifications in time, space, and under stress. [PDF]

New Phytol
Summary In roots, cell‐type‐specific differentiation enables specialized responses to environmental stress. The cortex, located between the vasculature and epidermis, is a key site for stress‐responsive modifications. The distinct specializations of the cortex are controlled by developmental, positional and environmental signals.

Transcription factors SlMYB41, SlMYB92, and SlWRKY71 regulate gene expression in the tomato exodermis. [PDF]

J Exp Bot
AbstractRoot barrier cell types, like the endodermis and exodermis, are crucial for plant acclimation to environmental stresses. Deposition of suberin, a hydrophobic polymer, in these cell layers restricts the movement of molecules and plays a vital role in stress responses.

The exodermis: A forgotten but promising apoplastic barrier

Journal of Plant Physiology, 2023
The endodermis and exodermis are widely recognized as two important barriers in plant roots that play a role in regulating the movement of water and ions. While the endodermis is present in nearly all plant roots, the exodermis, characterized by Casparian strips and suberin lamellae is absent in certain plant species.

Auxin Signaling Mediated Spatial Accommodation Mechanisms During Lateral Root Development. [PDF]

Physiol Plant
ABSTRACT Spatial accommodation, the ability of plant tissues to adapt structurally during organogenesis, is important for the successful growth and emergence of new organs, such as lateral roots, through overlying cell layers. This process requires precise coordination between cellular architecture and physical as well as biochemical signals.

The exodermis: a variable apoplastic barrier [PDF]

Journal of Experimental Botany, 2001
The exodermis (hypodermis with Casparian bands) of plant roots represents a barrier of variable resistance to the radial flow of both water and solutes and may contribute substantially to the overall resistance. The variability is a result largely of changes in structure and anatomy of developing roots. The extent and rate at which apoplastic exodermal

Regulation and function of a polarly localized lignin barrier in the exodermis. [PDF]

Nat Plants, 2022
ABSTRACTMulticellular organisms control interactions with their environment through the development of specialized barriers in specific cell types. A conserved barrier in plant roots is the endodermal Casparian strip (CS). The CS is made of polymerized lignin and forms a ring-like structure that seals the apoplastic space between the endodermal cells ...

Rice OsCASP1 orchestrates Casparian strip formation and suberin deposition in small lateral roots to maintain nutrient homeostasis

Frontiers in Plant Science, 2022
Arabidopsis Casparian strip membrane domain proteins (CASPs) form a transmembrane scaffold to recruit lignin biosynthetic enzymes for Casparian strip (CS) formation.
