• Root Exudation: The Ecological Driver of Hydrocarbon Rhizoremediation (2016, background): “Although other unrelated studies have demonstrated transport via vesicles in plant leaves, there is no evidence that this mechanism exists in the roots, except for mucilage polysaccharides transported by Golgi through the root cap [171].”
• Root structure and functioning for efficient acquisition of phosphorus: Matching morphological and physiological traits. (2006, background): “Phenolics and mucilage act in the same way as carboxylates (Guppy et al., 2005), but tend to be less effective than carboxylates (Neumann and Römheld, 2001).”
• Root exudation of sugars, amino acids, and organic acids by maize as affected by nitrogen, phosphorus, potassium, and iron deficiency (2011, background): “Dicotyledonous plants generally respond to P deficiency by increasing root exudation of carboxylates (Neumann and Römheld, 2000), and this response is often observed at later stages of P deficiency (Johnson et al.”
• Elevation of atmospheric CO2 and N-nutritional status modify nodulation, nodule-carbon supply, and root exudation of Phaseolus vulgaris L. (2007, background): “The 2 h-short-term collection of root secretes was performed to reduce microbial degradation of root exudates and to recover a high proportion of root exudates (Neumann and Römheld, 2000; Neumann, 2007).”
• MANGANESE AS ESSENTIAL AND TOXIC ELEMENT FOR PLANTS: TRANSPORT, ACCUMULATION AND RESISTANCE MECHANISMS (2010, background): “Neumann and Römheld (2001) reported that mobilization of micronutrients (including Mn) into the rhizosphere is due mainly by its acidification and complexation with the organic acids (citrate) in various plant species.”
• Crop rotational diversity increases disease suppressive capacity of soil microbiomes (2018, background): “Chemically, cover crops are providing more carbon to the soil through residues, but also root exudation of recently assimilated photosynthate, composed of soluble, low molecular weight organic compounds (Neumann and Romheld 2007).”
• The rhizosphere as a reservoir for opportunistic human pathogenic bacteria. (2005, background): “A long list of diverse substances, such as organic acids, sugars, amino acids, vitamins, polymeric carbohydrates is known to release by plant roots (Neumann and Römheld, 2001).”
• Impact of Nutrient Seed Priming on Germination, Seedling Development, Nutritional Status and Grain Yield of Maize (2015, background): “stress factors such as P and Fe limitation, high pH and bicarbonate levels with the potential to induce the accumulation of carboxylates and phenolics in the root tissue (Neumann and Römheld, 2007).”
• Advances in Elucidating Beneficial Interactions Between Plants, Soil, and Bacteria (2013, background): “Furthermore, pathogen-infected plants have shown different root exudates composition containing different amounts of sugars or organic acids (Kamilova et al., 2006; Neumann and Römheld, 2007; Phillips et al., 2004).”
• Rhizosphere engineering and management for sustainable agriculture (2009, background): “Grass species, by contrast, rely on the release of compounds called phytosiderophores that help mine the poorly soluble Fe and deliver it to the root surface for uptake (Neumann and Römheld 2007).”
• Strategies and methods for studying the rhizosphere—the plant science toolbox (2009, methodology): “…on root-induced responses to nutrient limitations should consider the fact that plants under natural growth conditions are usually exposed simultaneously to a wide array of additional stress factors with differential impact on the expression of rhizosphere responses (Neumann and Römheld 2007).”
• Plant genotype strongly modifies the structure and growth of maize rhizosphere microbial communities (2010, background): “Fertilization influences plant physiological status, as high nutrient availability favours the release of root exudates, whereas low nutrient availability restricts the allocation of plant resources to root exudates (Neumann and Römheld, 2007).”
