Coniferous Root Exudate.
The literature on root exudate is replete with studies of factors influencing the quantity and cycle of its production. For the most part, this work has been done utilizing herbaceous species or vines, but citations are also available on some of the broad-leaved trees. Root exudate from conifers is rarely reported, but in the course of preparation of a thesis at the University of California it ...
متن کاملRoot signals that mediate mutualistic interactions in the rhizosphere.
A recent boom in research on belowground ecology is rapidly revealing a multitude of fascinating interactions, in particular in the rhizosphere. Many of these interactions are mediated by photo-assimilates that are excreted by plant roots. Root exudates are not mere waste products, but serve numerous functions to control abiotic and biotic processes. These functions range from changing the chem...
متن کاملOntogenetic variation of four cytokinins in soybean root pressure exudate.
Cytokinins exported from the root may be involved in the correlative control of plant development. To test this hypothesis in soybean ((Glycine max [L.] Merr. cv. McCall, cv Chippewa 64, and cv Hodgson 78), cytokinins were intercepted en route from the root to the shoot by collecting root pressure exudate from detopped roots. The quantities of four cytokinins in the exudate were studied through...
متن کاملIsoflavanones from the allelopathic aqueous root exudate of Desmodium uncinatum.
Three isoflavanones, 5,7,2',4'-tetrahydroxy-6-(3-methylbut-2-enyl)isoflavanone (1), 4",5"-dihydro-5,2',4'-trihydroxy-5"-isopropenylfurano-(2",3";7,6)-isoflavanone (2) and 4",5"-dihydro-2'-methoxy-5,4'-dihydroxy-5"-isopropenylfurano-(2",3";7,6)-isoflavanone (3) and a previously known isoflavone 5,7,4'-trihydroxyisoflavone [genistein (4)] were isolated and characterised spectroscopically from the...
متن کاملFlavonoids and strigolactones in root exudates as signals in symbiotic and pathogenic plant-fungus interactions.
Secondary plant compounds are important signals in several symbiotic and pathogenic plant-microbe interactions. The present review is limited to two groups of secondary plant compounds, flavonoids and strigolactones, which have been reported in root exudates. Data on flavonoids as signaling compounds are available from several symbiotic and pathogenic plant-microbe interactions, whereas only re...
