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

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

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

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

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

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.

Permeability of Iris germanica’s multiseriate exodermis to water, NaCl, and ethanol [PDF]
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.

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