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 a part of a wider secrete from plant roots known as root exudate. Plant roots secrete a variety of organic molecules into the surrounding soil, such as proteins, enzymes, DNA, sugars and amino acids, which are the building blocks of life. [3] [4] This collective secretion is known as root exudate.
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.

At night in some plants, root pressure causes guttation or exudation of drops of xylem sap from the tips or edges of leaves. Root pressure is studied by removing the shoot of a plant near the soil level. Xylem sap will exude from the cut stem for hours or days due to root pressure. If a pressure gauge is attached to the cut stem, the root ...
Dudleya viscida is a rare succulent plant known by common name as the sticky liveforever, sticky dudleya or the San Juan stylophyllum. It is endemic to California, where it is found on rocky slopes. It is unique among the genus Dudleya in that it has sticky, fragrant leaves, a trait only shared with Dudleya anomala.
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 ]
