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.

An ABC Transporter Is Involved in the Silicon-Induced Formation of Casparian Bands in the Exodermis of Rice [PDF]

Frontiers in Plant Science, 2017
Silicon (Si) promotes the formation of Casparian bands (CB) in rice and reduces radial oxygen loss (ROL). Further transcriptomic approaches revealed several candidate genes involved in the Si-induced formation of CB such as ATP binding cassette (ABC ...

Identification of Critical Amino Acid Residues Required for the Polar Localization of a Rice Manganese Transporter. [PDF]

Plant Biotechnol J
ABSTRACT Rice has developed an efficient system for manganese (Mn) uptake, mediated by two distinct transporters, OsNramp5 and OsMTP9. These transporters exhibit polar localization at the root exodermis and endodermis; however, the mechanisms underlying their polar localization and their role in Mn uptake remain unclear.

A suberized exodermis is required for tomato drought tolerance [PDF]

SSRN Electronic Journal, 2022
SUMMARY Plant roots integrate environmental signals and developmental programs using exquisite spatiotemporal control. This is apparent in the deposition of suberin, an apoplastic diffusion barrier, which regulates the entry and exit of water, solutes and gases, and is environmentally plastic.

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 ...

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

Nat Plants, 2022
ABSTRACT Multicellular 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).

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 cells.

The Full-Size ABCG Transporter of Medicago truncatula Is Involved in Strigolactone Secretion, Affecting Arbuscular Mycorrhiza

Frontiers in Plant Science, 2020
Strigolactones (SLs) are plant-derived signaling molecules that stimulate the hyphal branching of arbuscular mycorrhizal fungi (AMF), and consequently promote symbiotic interaction between the fungus and the plant.

Apoplastic histochemical features of plant root walls that may facilitate ion uptake and retention

Open Life Sciences, 2021
We used brightfield and epifluorescence microscopy, as well as permeability tests, to investigate the apoplastic histochemical features of plant roots associated with ion hyperaccumulation, invasion, and tolerance of oligotrophic conditions.

Root structure syndromes of four families of monocots in the Middle Urals

Plant Diversity, 2023
The present article tests the following general assumption: plant taxa with different specializations towards mycorrhizal interactions should have different root syndromes. Roots of 61 species common in boreal zone were studied: 16 species of Poaceae, 24
