ROOT. That part of a tree or plant under ground from which it draws most of its nourishment from the earth.
     2. When the roots of a tree planted in one man's land extend into that of another, this circumstance does not give the latter any right to the tree, though such is the doctrine of the civil law; Dig. 41, 1, 7, 13; but such person has a right to cut off the roots up to his line. Rolle's R. 394, vide Tree.
     3. In a figurative sense, the term root is used to signify the person from whom one or more others are descended. Vide Descent; Per stirpes.

Ectomycorrhizae are a type of mycorrhizae that procedure a dense sheath around the physical structure of plant roots, from which the hyphae grow; in endomycorrhizae, mycelium is entrenched within the root tissue, not forming a sheath around the root system.
Bacteria were isolated from the non-rhizosphere soil,rhizosphere soil and plant root samples using the methods of Odunfa and Oso [11], Akinynaju and Fadayomi [12], Oyeyiola and Hussain [13,14] and Oyeyiola [10].
One of the biggest underground markets on the planet-nutrient trading between plant roots and fungi--turns out to run on a system of reciprocal rewards for good suppliers and less business for bad ones.
With funding from USDA's Cooperative State Research, Education, and Extension Service (CSREES) National Research Initiative (NRI), Mario Biondini at North Dakota State University found a way to more accurately predict water uptake from plant roots by improving upon the West, Brown, and Enquist (WBE) general model for scaling laws in biological networks.
Gardner (1960) used the single root approach to describe the dynamic aspect of water uptake by a plant, and to examine the soil water suction required at the boundary between the plant root and the soil in order to maintain a constant rate of water movement to the plant.
Of particular interest to Douds were results showing that plots farmed with two organic systems had greater AM fungi spore populations and produced greater plant root colonization than did soils from a conventional corn-soybean rotation system.
However, it seems that the decrease in transpiration, which is proportional to water uptake by the plant root, is less sensitive to decreasing water potential at the soil-root interface.
Water will shed rather than penetrate, thus starving the plant roots for moisture as well as excluding the movement of fresh oxygen into the soil.

Most other containers can be reused without any alterations, but if you want to further reduce the risk of damage to plant root balls over the winter, lining the sides of the pot (but not the bottom, because this could prevent adequate drainage) with bubble wrap before you put the compost in will help.
Easy answer -- the plant root drowns, and the above-ground plant parts die.
The ARS scientists think the most important action is not necessanly what reductase does to iron, copper, or manganese, but what it might be doing to sulfur--specifically, sulfur in a protein that makes up the openings to microscopic channels in plant root cells' outer membrane.
