TLDR
Sterile and non-sterile roots of sunflower seedlings were shown to reduce an insoluble higher oxide of Mn directly as discussed by the authors, and 12 other plant species were also capable of the same reduction.Abstract:
Sterile and non‐sterile roots of sunflower seedlings were shown to reduce an insoluble higher oxide of Mn directly. Non‐sterile roots of 12 other plant species were also shown to be capable of the same reduction.read more

Phytoremediation: A Novel Strategy for the Removal of Toxic Metals from the Environment Using Plants
David E. Salt,Michael J. Blaylock,Nanda P. B. A. Kumar,Viatcheslav. Dushenkov,Burt D. Ensley,Ilan Chet,Ilya Raskin +6 more
TL;DR: Biological mechanisms of toxic metal uptake, translocation and resistance as well as strategies for improving phytoremediation are also discussed.

Plant-driven selection of microbes
TL;DR: The general part of the manuscript is followed by the more detailed presentation of specific examples for the selection and interaction of roots and microbes, such as in the rhizosphere of strawberry, potato and oilseed rape, where the soil-borne plant pathogen Verticillium dahliae can cause high yield losses; the potential of biocontrol by specific constituents of the Rhizosphere microbial community is demonstrated.

The acquisition of phosphorus byLupinus albus L.: III. The probable mechanism by which phosphorus movement in the soil/root interface is enhanced
TL;DR: In this paper, it is shown that large quantities of citrate ions have been shown to be secreted by the roots ofLupinus albus and that these react in the soil to form ferric hydroxy phosphate polymers which diffuse to the root surface where they are degraded by the action of reducing agents in the presence of an Fe II uptake mechanism balanced by hydrogen ion secretion.

Types, amounts, and possible functions of compounds released into the rhizosphere by soil-grown plants
TL;DR: The rhizosphere is defined here as that volume of soil affected by the presence of the roots of growing plants as discussed by the authors, and it is defined as the area of the soil that can be changed by the growth of a plant.

Obligatory reduction of ferric chelates in iron uptake by soybeans.
TL;DR: Separation and absorption of Fe from Fe(3+)-chelates appear to require reduction of Fe( 3+)-chelate to Fe(2+-chelate at the root, with Fe( 2+) being the principal form of Fe absorbed by soybean.

Root-Soil Boundary Zones as Seen in the Electron Microscope1
Hans Jenny,Karl Grossenbacher +1 more
TL;DR: These micrographs show greatly enlarged views of the outer edges of root cells in contact with the soil, a jelly-like coating on the outer surface of the roots that conforms to the surface contour of the soil particles it touches.

Root-soil boundary zones as seen by the electron microscope
H Jenny,K Grossenbacher +1 more
TL;DR: The mucigel, a jelly-like coating on the outer surface of the roots, conforms to the surface contour of the soil particles it touches as discussed by the authors, and intimate contact is provided for the transfer of soil nutrient ions and water from the soil to the roots.
