Rhizosphere-Scale Quantification of Hydraulic and Mechanical Properties of Soil Impacted by Root and Seed Exudates

open access: yesVadose Zone Journal, 2018
Using rhizosphere-scale physical measurements, we tested the hypothesis that plant exudates gel together soil particles and, on drying, enhance soil water repellency. Barley ( L. cv. Optic) and maize ( L. cv. Freya) root exudates were compared with chia (

Root developmental responses to heterogeneous water and nitrogen supply [PDF]

open access: yes, 2012
Better understanding of the interaction between the soil physical properties determining water and nitrate availability and the root proliferation and gene expression components of nutrient acquisition could contribute to food security, but may have been

Root exudates impact plant performance under abiotic stress

open access: yes, 2022
Plant root exudates serve pivotal roles in supporting plant development and interactions with the physicochemical and biological factors in the rhizosphere.

Allelopathic effects of potato root exudates on Andrographis paniculata seedings under cinnamic acid stress

open access: yesGuangxi Zhiwu
In order to confirm the viability of the potato-Andrographis paniculata rotation mode, and to investigate the effect mechanism of potato root exudates on phenolic acid allelochemicals in the potato-A.

Plant mechanisms contributing to acid impairment of nodulation of Medicago murex and Medicago sativa by Sinorhizobium medicae

open access: yes, 2003
The widespread sowing of the perennial forage legume Medicago sativa to lower groundwater tables in south-western Australia is limited as many soils targeted for its use are too acidic (pHCaCl2 < 5) for consistent nodulation with Sinorhizobium spp.

Nitrogen Input Alters Root Exudation of Kandelia obovata and Nitrogen Cycling in Constructed Mangrove Wetlands

open access: yesPlants
The role of mangrove root exudates in mediating the nitrogen cycle, particularly under high dissolved inorganic nitrogen (DIN) input, in coastal ecosystems remains unclear.

Uptake and Exudation of Phenolic Compounds by Wheat and Antimicrobial Components of the Root Exudate

open access: yesZeitschrift für Naturforschung C, 1996
Abstract In the course of our study, it was found that phenyl propenoic acid derivatives were readily taken up by wheat. Leaf leachate components were chosen for the feeding experiments and p-coumaric acid, ferulic acid and caffeic acid were found to be quickly taken up into the plants via the roots.

Effects of Root Exudates on Seed Germination and Seedling Growth of Wolfberry (Lycium barbarum L.) and the Development of Root Rot Diseases

open access: yesAgronomy
Root exudates play a critical role in enabling plants to respond to environmental stresses and mediate information exchange within the rhizosphere. These compounds regulate plant–rhizosphere interactions and significantly influence the structural and ...

Environmental and Biological Drivers of Root Exudation

open access: yesAnnual Review of Plant Biology
Root exudation is the process by which plants release organic and inorganic metabolites from their roots into the surrounding soil. Root exudation is a dynamic process and shapes plant–environment interactions at the root–soil interface. Little is known about the biological and environmental factors that shape the exuded metabolome, hereafter referred ...

Root exudates and local resource environments.

open access: yes, 2014
(a) Schematic of root exudates in the model. Small open circles are general exudates that are usable by any free-living cells. Blue circles are nodulation induced exudates (bN), also available to all free-living cells. Red triangles are rhizopines, which
