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.

Dynamics of root exudates

2011
Mit dieser Masterarbeit wurde versucht verschiedene Fragestellungen zu bearbeiten, die alle im Zusammenhang mit der Dynamik von Wurzelexsudaten stehen. Zuerst sollte mit einem breit angelegten Versuch ("Artspezifische Variation"/Experiment 1) verifiziert werden, ob die von uns gewählte Methode der Exsudatgewinnung und -aufbereitung sensitiv genug ist ...

Root Pressure Exudation from Apical Root Segments

Nature, 1966
THE question of why some plants exhibit copious exudation and others show little or none has remained unanswered. Very few comparative investigations of variations in root pressure among species, however, have been carried out. Reports of root pressure exudation have been based on independent observations of a wide range of materials, from cut stumps ...

Genetic control of root exudation

Plant and Soil, 2002
The literature on genetics of root exudation and on genotypic differences in qualitative and quantitative composition of root exudates in crop and native plant species was critically assessed. Differences in exudation have been reported for genotypes that differ in tolerance to nutrient deficiencies, ion toxicities, and pathogen attack.

Root Exudates and Nutrient Cycling

2007
In addition to their role as organs for anchorage in soil, soil exploitation, and uptake of water and nutrients, plant roots can modify the physico-chemical conditions in the surrounding soil via alterations of root activity. The soil volume that is directly or indirectly influenced by the activity of plant roots is called the rhizosphere (Hinsinger ...
