ROOTS OF SOBRALIA MACRANTHA (ORCHIDACEAE): STRUCTURE AND FUNCTION OF THE VELAMEN‐EXODERMIS COMPLEX
Roots of Sobralia macrantha, a largely terrestrial orchid, bear a typical multilayered velamen underlaid by a cortical exodermis. The latter consists of densely cytoplasmic passage cells regularly interspersed among much larger, elongate, vacuolate cells.

Regulatory Roles of MYB Transcription Factors in Root Barrier Under Abiotic Stress [PDF]
Plant 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.

Significance of the exodermis in root function
An exodermis is a specialized type of hypodermis which often occurs in roots. The hypodermis, like the endodermis, is part of the cortex since it is derived from the ground meristem. The hypodermis and endodermis form the outer and inner boundaries of the cortex, respectively.

OsPIP2;4 aquaporin water channel primarily expressed in roots of rice mediates both water and nonselective Na+ and K+ conductance [PDF]
Aquaporin (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 ...

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

Physiological and anatomical differences between subtropical forage plants grown in waterlogged alkaline-sodic soil [PDF]
The objective of this work was to evaluate the effects of 26 days of waterlogging, compared with field capacity, on different traits of the forage plants 'Finecut' Chloris gayana, 'Klein Verde' Panicum coloratum, and 'Shawnee' Panicum virgatum, grown in ...

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