Root exudate signals in plant–plant interactions

Plant, Cell & Environment, 2020
AbstractPlant‐to‐plant signalling is a key mediator of interactions among plant species. Plants can perceive and respond to chemical cues emitted from their neighbours, altering survival and performance, impacting plant coexistence and community assembly. An increasing number of studies indicate root exudates as key players in plant‐to‐plant signalling.

Factors Affecting Root Exudation

1971
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. Substances (other than water) which are released from plant surfaces have been termed as “exudates” by many investigators, regardless of whether their appearance on the ...

Root exudates mediated interactions belowground

Soil Biology and Biochemistry, 2014
The root exudate composition reflects the contradictory-concomitantly attractive and repulsive-behaviour of plants towards soil microorganisms. Plants produce antimicrobial, insecticide and nematicide compounds to repel pathogens and invaders. They also produce border cells that detach from roots and play an important role as biological and physical ...

Root Communication: The Role of Root Exudates

2004
Plants communicate with neighboring plants and other organisms surrounding them. Aboveground communication isarticulatedthroughstems,leaves,orflowerswhilebelow-groundcommunication ismediated by roots.

Sorgoleone from root exudate inhibits mitochondrial functions

Journal of Chemical Ecology, 1992
The aim of this investigation was to determine if sorgoleone (SGL), a hydrophobic compound inSorghum bicolor (L.) Moench root exudate, interferes with mitochondrial functions. Tests were conducted on mitochondria isolated from etiolated soybean [Glycine max (L.) Merr.] and corn (Zea mays L.) seedlings. The data show SGL is a potent inhibitor of state 3

Methods for Root Exudate Collection and Analysis

2020
Plant root exudation has long been recognized as a vital communication system between plants and microbial communities populating the rhizosphere. Due to the high complexity of the collection process and analysis, a variety of techniques have been developed to mimic natural exudation conditions.

Root Exudation: An In‐Depth Experimental Guide

Plant, Cell & Environment
ABSTRACTPlants exude a wide variety of compounds into the rhizosphere, modulating soil functioning and diversity. The number of studies investigating exudation has exponentially increased over the past decades. Yet, the high inter‐study variability of the results is slowing down our understanding of root–soil interactions.

Effects of root exudate sorgoleone on photosynthesis

Journal of Chemical Ecology, 1993
The aim of this investigation was to determine if sorgoleone (SGL), ap-benzoquinone inSorghum bicolor root exudate, is a photosynthesis inhibitor. Assays usingGlycine max leaf disks showed concentrations as low as 10μM SGL inhibited oxygen evolution more than 50%.

Soil organic matter mobilization by root exudates

Chemosphere, 2000
In order to study the different soil organic matter mobilisation by agrarian (Zea mais: cultivars Paolo and Sandek) and forest (Picea abies Karst. and Pinus sylvestris L.) root exudates, three different soils (Dystric Spodic Cambisol--S1, Haplic Luvisol--S2 and Calcaric Cambisol--S3) have been considered.

Chemotaxis of Zoospores for Root Exudates

Science, 1961
A chemotactic response of the zoospores of a soil-inhabiting plant pathogenic fungus, Phytophthora cinnamomi, for roots of avocado seedlings was observed. The chemotaxis of the zoospores and chemotropy of their germ tubes were directly related to infection and disease production.
