The rhizosphere is the thin area of soil immediately surrounding the root system. It is a densely populated area in which the roots compete with invading root systems of neighboring plant species for space, water, and mineral nutrients as well as form positive and negative relationships with soil-borne microorganisms such as bacteria, fungi and insects.
Root mucilage is made of plant-specific polysaccharides or long chains of sugar molecules. [1] [2] This polysaccharide secretion of root exudate forms a gelatinous substance that sticks to the caps of roots. [3] Root mucilage is known to play a role in forming relationships with soil-dwelling life forms.
Plant seeds exudate a variety of molecules into the spermosphere, [13] and roots exudate into the rhizosphere; these exudates include acids, sugars, polysaccharides and ectoenzymes, and collectively account for 40% of root carbon. [14] Exudation of these compounds has various benefits to the plant and to the microorganisms of the rhizosphere ...
Guttation is the exudation of drops of xylem and phloem sap on the tips or edges of leaves of some vascular plants, such as grasses, and also a number of fungi. Ancient Latin gutta means "a drop of fluid", whence modern botany formed the word guttation to designate that a plant exudes drops of fluid onto the outer surface of the plant, when the ...
Galium aparine, with common names including cleavers, clivers, catchweed, robin-run-the-hedge, goosegrass, and sticky willy, is an annual, herbaceous plant of the family Rubiaceae. Names [ edit ]
A sundew with a leaf bent around a fly trapped by mucilage. Mucilage is a thick gluey substance produced by nearly all plants and some microorganisms.These microorganisms include protists which use it for their locomotion, with the direction of their movement always opposite to that of the secretion of mucilage.

Geranium viscosissimum displayed a capability to digest and absorb the 14 C-labeled algal protein placed on the sticky trichomes that the plant possesses. However, it is not known whether the digestive enzymes were produced by the plant itself or surface microbes. [ 5 ]
The seeds are burs, and are very sticky. The plant is native but a well-known nuisance in deciduous forests of the eastern U.S. because the seeds can be difficult to remove from clothing and especially pet fur. [8] [9] The seeding part of the plant—the upper stem—dies earlier than most other plants, and becomes very brittle. Often the ...
