Exodermis lignification impacts lateral root emergence in Brachypodium distachyon
bioRxivSummary Rationale 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.

Permeability of Iris germanica’s multiseriate exodermis to water, NaCl, and ethanol [PDF]
Journal of Experimental Botany, 2010 The exodermis of Iris germanica roots is multiseriate. Its outermost layer matures first with typical Casparian bands and suberin lamellae. But as subsequent layers mature, the Casparian band extends into the tangential and anticlinal walls of their ...

Regulatory Roles of MYB Transcription Factors in Root Barrier Under Abiotic Stress [PDF]
PlantsPlant roots form highly specialized apoplastic barriers that regulate the exchange of water, ions, and solutes between the soil and vascular tissues, thereby protecting plant survival under environmental stress.

OsPIP2;4 aquaporin water channel primarily expressed in roots of rice mediates both water and nonselective Na+ and K+ conductance [PDF]
Scientific ReportsAquaporin (AQP)-dependent water transport across membranes is indispensable in plants. Recent evidence shows that several AQPs, including plasma membrane intrinsic proteins (PIPs), facilitate the electrogenic transport of ions as well as water transport ...

Microscopy and spatial-metabolomics identify tissue-specific metabolic pathways uncovering salinity and drought tolerance mechanisms in Avicennia marina and Phoenix dactylifera roots [PDF]
Scientific ReportsIn arid and semi-arid climates, native plants have developed unique strategies to survive challenging conditions. These adaptations often rely on molecular pathways that shape plant architecture to enhance their resilience.

Rice Science, 2021 Abstract Exploration of novel genetic resources against root-knot nematode (RKN) is necessary to strengthen the resistance breeding program in cultivated rice, and investigations on the role of genotype-specific root anatomy in conferring a structural barrier against nematode invasion are largely underexplored.

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

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

Asymmetrical development of root endodermis and exodermis in reaction to abiotic stresses. [PDF]
Annals of Botany, 2016 Background and Aims In the present study, we show that development of endodermis and exodermis is sensitively regulated by water accessibility. As cadmium (Cd) is known to induce xeromorphic effects in plants, maize roots were exposed also to Cd to understand the developmental process of suberin lamella deposition in response to a local Cd source ...
