Variation in morphological and physiological parameters in herbaceous perennial legumes in response to phosphorus supply (2010, unknown): “For instance, barley genotypes with long root hairs are better adapted to low-P soils and have higher yield potential than genotypes with short root hairs (Gahoonia and Nielsen 2004).”
Genotypic variation in phosphorus efficiency between wheat cultivars grown under greenhouse and field conditions (2006, background): “…including changes in rhizosphere pH, release of organic compounds, increases in root surface area and the efficient use of P at the cellular level (Gahoonia and Nielsen 2004; Lynch and Brown 2001; Raghothama and Karthikeyan 2005; Rengel and Correspondence: A. GUNES, Department of Soil Science and…”
Soil and fertilizer phosphorus in relation to crop nutrition (2008, background): “In contrast, cultivars with short root hairs produced small grain yields in P-limited soils and produced large grain yields only in P-sufficient soils (Gahoonia and Nielsen 2004).”
Acquisition of phosphorus and other poorly mobile nutrients by roots. Where do plant nutrition models fail? (2011, background): “…for root hairs (Bhat et al. 1976; Bouldin 1961; Itoh and Barber 1983a,b; Leitner et al. 2010b; Nye 1966; Passioura 1963), which play a prominent role in extending the volume of the depletion zone in the rhizosphere, as clearly demonstrated for P (Gahoonia and Nielsen 2004a,b; Gahoonia et al. 2001).”
Root structure and functioning for efficient acquisition of phosphorus: Matching morphological and physiological traits. (2006, background): “However, a decrease in root diameter is by no means a universal response to a low Pi supply (e.g. Borch et al., 1999; Schroeder and Janos, 2005).”
Root phenotypes for improved nutrient capture: an underexploited opportunity for global agriculture. (2019, background): “Substantial phenotypic variation for root hair length and density are present in crop germplasm, and genotypes with longer, denser hairs have much greater P capture from low-P soil (Gahoonia & Nielsen, 2004b; Lynch, 2011; Fig.”
Carboxylate release of wheat, canola and 11 grain legume species as affected by phosphorus status (2006, background): “Several plant traits or soil chemical interactions can affect the availability of P in soils including the release of large quantities of carboxylates such as citrate and malate (Jones 1998; Ryan et al. 2001), rhizosphere pH interactions (Hinsinger 2001), morphological changes such as increasing the”
Plant performance in stressful environments: interpreting new and established knowledge of the roles of arbuscular mycorrhizas (2009, background): “Long, finely branched root systems and roots with long root hairs are important in increasing effectiveness in acquisition of relatively immobile inorganic nutrients such as P and Zn (Gahoonia and Nielsen 2004a, b).”
Role of Macronutrients in Plant Growth and Acclimation: Recent Advances and Future Prospective (2014, background): “But wideranging fertilization in the crop fields with extensive P leads to fast exhaustion of nonrenewable P wealth, and therefore contributes to environmental pollution; however, its deficiency in soil causes significant reduction in crop yields (Elliott et al. 1997; Vance et al. 2003; Gahoonia and”
Management of soil phosphorus and plant adaptation mechanisms to phosphorus stress for sustainable crop production: a review (2012, unknown): “However, since fine roots tend to turnover more rapidly than coarse roots, the carbon cost of producing finer roots may be higher as these will have to be replaced more frequently (Sattelmacher et al., 1994; Gahoonia and Nielsen, 2004b).”
