Roots Structure and Development of Austrobaileya scandens (Austrobaileyaceae) and Implications for Their Evolution in Angiosperms [PDF]

open access: yes, 2020
Since the resolution of the ANA grade [Amborellales, Nymphaeales, Austrobaileyales] as sister to all other flowering plants, a few comparative studies of root structure have suggested that some of their anatomical traits could be of importance to ...

Effects of Ag and Pb metal accumulation on some biochemical parameters and anatomical characteristics of Sesuvium portulacastrum L. (Aizoaceae) plants [PDF]

open access: yesCaspian Journal of Environmental Sciences, 2022
The study reported the effect of contamination of Sesuvium portulacastrum L. after exposure to Ag and Pb for four weeks. The results showed that the total protein, chlorophyll, carotene, and biomass declined gradually by elevating   the heavy metal ...

Composite Transport Model and Water and Solute Transport across Plant Roots: An Update

open access: yesFrontiers in Plant Science, 2018
The present review examines recent experimental findings in root transport phenomena in terms of the composite transport model (CTM). It has been a well-accepted conceptual model to explain the complex water and solute flows across the root that has been

Pythium species from rice roots differ in virulence, host colonization and nutritional profile [PDF]

open access: yes, 2013
Background: Progressive yield decline in Philippine aerobic rice fields has been recently associated with three closely related Pythium spp., P. arrhenomanes, P. graminicola and P. inflatum.

Root Morphology and Anatomy Affect Cadmium Translocation and Accumulation in Rice

open access: yesRice 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.

Groups of multi-cellular passage cells in the root exodermis of Echinochloa crus-galli varieties lack not only suberin lamellae but also lignin deposits

open access: yesPlant Signalling & Behavior, 2020
Passage cells are frequently found in the exodermis and the endodermis of the roots. Because passage cells lack an apoplastic diffusion barrier, they are thought to provide pathways for the transport of nutrients and the entrance of endomycorrhizal fungi.

Does suberin accumulation in plant roots contribute to waterlogging tolerance?

open access: yesFrontiers 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 ...

Environmental effects on the maturation of the endodermis and multiseriate exodermis of Iris germanica roots. [PDF]

open access: yesAnnals of Botany, 2009
Most studies of exodermal structure and function have involved species with a uniseriate exodermis. To extend this work, the development and apoplastic permeability of Iris germanica roots with a multiseriate exodermis (MEX) were investigated. The effects of different growth conditions on MEX maturation were also tested. In addition, the exodermises of

Variation in root morphology of epiphytic orchids along small-scale and large-scale moisture gradients [PDF]

open access: yesActa Botânica Brasílica
Root 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

open access: yesBiologia 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 "
