Soil and fertilizer phosphorus in relation to crop nutrition (2008, background): “In contrast to white lupin, these species, which grow on highly weathered acid soils, do not release protons together with carboxylates into the rhizosphere (Roelofs et al. 2001).”
Variation in morphological and physiological parameters in herbaceous perennial legumes in response to phosphorus supply (2010, unknown): “However, the effects of carboxylate efflux on pH are complex and carboxylate exudation is not invariably associated with acidification (Roelofs et al. 2001).”
Plant mechanisms to optimise access to soil phosphorus (2009, background): “) form proteiod roots that secrete organic anions in response to P deficiency, and these structures are regarded as an important evolutionary adaptation for plant growth in low P soils (Roelofs et al. 2001).”
Root structure and functioning for efficient acquisition of phosphorus: Matching morphological and physiological traits. (2006, background): “…the ‘compound’ (mat-forming) proteoid roots of Banksia integrifolia have also shown that carboxylates, such as citrate, are released into the rhizosphere (Grierson, 1992; Roelofs et al., 2001), but there are no reports on the time course of carboxylate exudation in taxa that produce compound roots.”
Plant and microbial strategies to improve the phosphorus efficiency of agriculture (2011, background): “In contrast, the exudation of a large range of organic anions from cluster roots of several members of the Proteaceae is not associated with acidification (Roelofs et al. 2001).”
Plant root growth, architecture and function (2009, background): “Unlike lupins however, no proton release accompanied the release of the carboxylates in these species (Roelofs et al. 2001).”
Plant mineral nutrition in ancient landscapes: high plant species diversity on infertile soils is linked to functional diversity for nutritional strategies (2010, background): “2008b), we explore if species with root clusters (Lambers et al. 2006; Roelofs et al. 2001) are relatively more prominent and mycorrhizal species relatively less prominent (Brundrett 2009) on the most P-impoverished soils in OCBILs.”
Mixed culture of wheat (Triticum aestivum L.) with white lupin (Lupinus albus L.) improves the growth and phosphorus nutrition of the wheat (2005, background): “The proteoid roots of the Proteaceae exude a range of organic acid anions that make soil P more available to plants either by chelating soil cations that react with phosphate or by displacing phosphate from adsorption sites on positively charged soil particles (Roelofs et al., 2001).”
