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.
This important relationship is known to affect 94% of land plants, [11] and benefits plants by increasing water and nutrient uptake from the soil, particularly phosphorus. In return, the fungi receive food in the form of carbohydrates from the plant in the form of broken-down root mucilage. Without this relationship, many plants would struggle ...
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 ...
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.

Galium aparine is known by a variety of common names in English. They include ' 'sweetheart', 'hitchhikers, cleavers, [2] clivers, bedstraw, (small) goosegrass (not to be confused with other plants known as goosegrass), [2] catchweed, [2] stickyweed, sticky bob, [3] stickybud, stickyback, sticky molly, robin-run-the-hedge, sticky willy, [2] [4] sticky willow, stickyjack, stickeljack, grip ...
Plant development is the process by which structures originate and mature as a plant grows. It is studied in plant anatomy and plant physiology as well as plant morphology. Plants constantly produce new tissues and structures throughout their life from meristems [ 35 ] located at the tips of organs, or between mature tissues.
Honeydew is a sugar-rich sticky liquid, secreted by aphids, some scale insects, and many other true bugs and some other insects as they feed on plant sap. When their mouthpart penetrates the phloem , the sugary, high-pressure liquid is forced out of the anus of the insects, allowing them to rapidly process the large volume of sap required to ...
Further evidence that arbuscular mycorrhizal fungi exhibit host-specific chemotaxis, that enable hyphal growth toward the roots of a potential host plant: Spores of Glomus mosseae were separated from the roots of a host plant, nonhost plants, and dead host plant by a membrane permeable only to hyphae. In the treatment with the host plant, the ...
