Root exudates: from plant to rhizosphere and beyond

Plant Cell Reports, 2019
This article describes the composition of root exudates, how these metabolites are released to the rhizosphere and their importance in the recruitment of beneficial microbiota that alleviate plant stress. Metabolites secreted to the rhizosphere by roots are involved in several processes.

Production of recombinant proteins in plant root exudates

Nature Biotechnology, 1999
The large-scale production of recombinant proteins in plants is limited by relatively low yields and difficulties in extraction and purification. These problems were addressed by engineering tobacco plants to continuously secrete recombinant proteins from their roots into a simple hydroponic medium. Three heterologous proteins of diverse origins (green

Impact of Plant Exudates on Soil Microbiomes

2021
The plant exits root exudate into the rhizosphere. This exudate acts as a regulator of soil microbial communities around the roots and supports a favorable symbiosis between plants and microbes. This symbiotic mechanism occurs because the root exudate is a source of carbon and energy for microbes.

Root-Pressure Exudation in Woody Plants

Botanical Gazette, 1965
A study was made of differences in amount and concentration of root-pressure exudate from detopped root systems of several woody species. Root-pressure exudation was exhibited by young grape plants and young seedlings of tulip tree, birch, and red maple but not by loblolly pine, white spruce, and sugar maple. The salt concentration of the root-pressure

Plant Root Exudates as Determinant of Rhizomicrobiome

2020
The rhizosphere, a microecosystem, harbours numerous organisms such as bacteria, fungi, actinomycetes, and nematodes. The definite and diverse community that can grow or survive in the rhizosphere is called rhizomicrobiome. The community and activity of microorganisms could be enhanced and decided by the respective plants by the special molecules ...

Plant exudates promote PCB degradation by a rhodococcal rhizobacteria

Applied Microbiology and Biotechnology, 2011
Rhodococcus erythropolis U23A is a polychlorinated biphenyl (PCB)-degrading bacterium isolated from the rhizosphere of plants grown on a PCB-contaminated soil. Strain U23A bphA exhibited 99% identity with bphA1 of Rhodococcus globerulus P6. We grew Arabidopsis thaliana in a hydroponic axenic system, collected, and concentrated the plant secondary ...

Chemical Signatures of Fossilized Resins and Recent Plant Exudates

Angewandte Chemie International Edition, 2008
AbstractAmber is one of the few gemstones based on an organic structure. Found over most of the world, it is the fossil form of sticky plant exudates called resins. Investigation of amber by modern analytical techniques provides structural information and insight into the identity of the ancient plants that produced the source resin. Mass spectrometric

Root Exudates in Phosphorus Acquisition by Plants

2001
This chapter discusses the processes in the rhizosphere that are determined by exudates from roots and that in turn affect the availability of phosphorus to plants. These include control of rhizosphere pH, exudation of organic acids and root phosphatases.

Harnessing root exudates for plant microbiome engineering and stress resistance in plants

Microbiological Research
A wide range of abiotic and biotic stresses adversely affect plant's growth and production. Under stress, one of the main responses of plants is the modulation of exudates excreted in the rhizosphere, which consequently leads to alterations in the resident microbiota.
