Water soluble organic molecules synthesized in the plant may make their way to the surface
of the root and be lost into the surrounding medium. Photosynthates from leaves are …

Conclusions Although the quantities of organic compounds exuding from roots is not large,
seldom exceeding 0.4% of the carbon photosynthesized, they do exert a very strong …

Hiltner's rhizosphere could not exist without the underlying phenomenon now most
commonly referred to as root exudation, which is associated with all higher plants. Other …

Our understanding of the biology, biochemistry, and genetic development of roots has
considerably improved during the last decade (Smith and Fedoroff, 1995; Flores et al., 1999; …

Publisher Summary The absorption and desorption of substances that are extremely diverse
in molecular size and in physicochemical and biological properties occur at the root surface …

Root exudation is an important ecological phenomenon which can manipulate plant and
microbial succession. Under sterile conditions only 5-10% of the fixed carbon is released by …

Publisher Summary Root exudates are involved in chelation and solubilization of nutrients,
in soil aggregation, and in effects on the pH of the soil solution. This chapter reviews …

Review of work on the nature of exudates (carbohydrates, amino acids, vitamins, organic
acids, nucleotides, flavonones, enzymes); factors affecting nematodes and fungi; factors …

The composition of root‐derived substances is of great importance for the understanding of
processes in the rhizosphere. Therefore, methods allowing a comprehensive collection and …

Root exudates from 3-week-old sugar maple seedlings and a 55-year-old mature tree were
analyzed for carbohydrates, amino acids/amides, and organic acids. Carbohydrates from …
