Root Morphology and Anatomy Affect Cadmium Translocation and Accumulation in Rice
Rice Science, 2021 Paddy fields contaminated with cadmium (Cd) present decreased grain yield and produce Cd-contaminated grains. Screening for low-Cd-accumulating cultivars is a useful method to reduce the amount of Cd in the grains.

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 ...

Does suberin accumulation in plant roots contribute to waterlogging tolerance?
Frontiers in Plant Science, 2013 Plants that are adapted to waterlogged conditions develop aerenchyma in roots for ventilation. Some wetland plant species also form an apoplastic barrier at the outer cell layers of roots that reduces radial oxygen loss (ROL) from the aerenchyma and to ...

Variation in root morphology of epiphytic orchids along small-scale and large-scale moisture gradients [PDF]
Acta Botânica BrasílicaRoot morphology is expected to respond to environmental conditions. Two earlier studies reported predictable changes in the structure of the velamen radicum (common in monocotyledons) along rainfall gradients, which was expected from its assumed role in ...

Tracing root permeability: comparison of tracer methods
Biologia Plantarum, 2016 Root epidermis and apoplastic barriers (endodermis and exodermis) are the critical root structures involved in setting up plant-soil interface by regulating free apoplastic movement of solutes within root tissues. Probing root apoplast permeability with "

Early development of epiphytic roots: perspectives based on the composition of the velamen cell wall [PDF]
Acta Botânica Brasílica, 2021 The velamen, a root structure of some epiphytic species for water uptake, usually is stratified epidermis consisting of dead cells. In general, its cell walls exhibit variation during development, including in thickness and amount and type of impregnated

A rapid staining method for the detection of suberin lamellae in the root endodermis and exodermis. [PDF]
Plant Biotechnol (Tokyo)Histochemical detection of suberin lamellae has remarkably advanced our understanding of the roles of the apoplastic diffusion barrier in the root endodermis and the oxygen diffusion barrier in the root exodermis. Fluorol yellow 088 detects the aliphatic component of suberin and is one of the most reliable stains for detecting suberin lamellae in the ...

Exodermis lignification impacts lateral root emergence in Brachypodium distachyon
Summary 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.

Apoplastic transport of abscisic acid through roots of maize: effect of the exodermis [PDF]
Planta, 2000 The exodermal layers that are formed in maize roots during aeroponic culture were investigated with respect to the radial transport of cis-abscisic acid (ABA). The decrease in root hydraulic conductivity (Lp(r)) of aeroponically grown roots was stimulated 1.5-fold by ABA (500 nM), reaching Lp(r) values of roots lacking an exodermis.
