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%.

Root Exudate Profiling in Sorghum

2023
Root exudation refers to the processes by which plants release compounds called root exudates into the soil. These exudates are primarily carbon-containing compounds that interact with microbial communities in the rhizosphere. Microbial consumption of exudates reduces the concentration of the exudated compounds in the soil, causing the plant to exude ...

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.

Plant root exudates

The Botanical Review, 1969
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 influence on the soil microorganisms and may be significant in affecting plant nutrient availability.

Exudation of terpenoids by cotton roots

Plant and Soil, 1978
The terpenoid aldehydes, desoxyhemigossypol, desoxy-6-methoxyhemigossypol, hemigossypol, 6-methoxyhemigossypol, gossypol, 6-methoxygossypol, and 6,6′-dimethoxygossypol, previously reported to be present in cotton roots (Gossypium hivsutum L.) were found on absorbing surfaces adjacent to roots.

Root-secreted proteins: an underexplored component of root exudates

Trends in Plant Science
Proteins are integral components of root exudates that mediate plant-microbe interactions, nutrient mobilization, and stress responses. Despite their importance, our understanding of their composition, regulation, and function is limited. Here, we summarize recent advances on root-exuded proteins, highlight pivotal outstanding questions, and propose ...

Root Exudation in Relation to Inoculation with Rhizobia

Zentralblatt für Bakteriologie, Parasitenkunde, Infektionskrankheiten und Hygiene. Zweite Naturwissenschaftliche Abteilung: Allgemeine, Landwirtschaftliche und Technische Mikrobiologie, 1976
Summary Root exudates of lucerne (Medicago sativa L.) and urid (Phaseolus mungo L.) were analyzed for reducing and non-reducing sugars, total and ortho-dihydroxy phenols, amino-nitrogen, polygalacturonase, and pectin methyl esterase. Upon inoculation with Rhizobium, there was an increase in the exudation of non-reducing sugars, ortho-dihydroxy ...

Proteoid Roots and Exudation of Proteases by Plant Roots

2011
Among the numerous strategies for improving P or N uptake by plants, development of proteoid roots and exudation of proteases can be found. Proteoid roots, which develop as a response to P deficiency during exudative burst secrete carboxylates and acid phosphatase, which improves P uptake.

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 ...

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 ...
