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 ...

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

Nat Plants, 2022
SUMMARYPlant 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.

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 ...

Tetraploidy enhances boron-excess tolerance in Carrizo Citrange (Citrus sinensis L. Osb. x Poncirus trifoliata L. Raf.) [PDF]

Frontiers in Plant Science, 2016
Tetraploidy modifies root anatomy which may lead to differentiated capacity to uptake and transport mineral elements. This work provides insights into physiological and molecular characters involved in boron (B) toxicity responses in diploid (2x) and ...

Silicon Promotes Exodermal Casparian Band Formation in Si-Accumulating and Si-Excluding Species by Forming Phenol Complexes. [PDF]

PLoS ONE, 2015
We studied the effect of Silicon (Si) on Casparian band (CB) development, chemical composition of the exodermal CB and Si deposition across the root in the Si accumulators rice and maize and the Si non-accumulator onion.

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.

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.

Nitric oxide alleviates cadmium- but not arsenic-induced damages in rice roots [PDF]

, 2020
Nitric oxide (NO) has signalling roles in plant stress responses. Cadmium (Cd) and arsenic (As) soil pollutants alter plant development, mainly the root-system, by increasing NO-content, triggering reactive oxygen species (ROS), and forming peroxynitrite
