rhizosphere
[ rī′zə-sfîr′ ]
The soil zone that surrounds and is influenced by the roots of plants. Within the rhizosphere, roots secrete a slimy lubricating substance, called mucigel, that cause the particles of soil to adhere to the roots, assisting in the uptake of water, and encourages the growth of nitrogen-fixing bacteria and other beneficial microorganisms.
