• ROOT STRATEGIES FOR PHOSPHORUS ACQUISITION (2008, background): “Root hairs are attractive targets for crop breeding programs because there is large genotypic variation, substantial effect of this variation on PAE (regardless of mycorrhizal status), relatively simple genetic control, and opportunities for direct phenotypic selection (Gahoonia and Nielsen 2004; Ly”
• 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).”
• Roots of the Second Green Revolution (2007, background): “The large genotypic variation for root-hair traits, and the substantial effect this variation has on phosphorus acquisition, regardless of mycorrhizal status, together with the relatively simple genetic control of these traits and opportunities for direct phenotypic selection, make them attractive t”
• 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).”
• Developments in breeding cereals for organic agriculture (2008, unknown): “…has low mobility in the soil and its uptake efficiency is dependent on soil exploration by roots, root hairs (possible for indirect selection: Gahoonia and Nielsen 2004a, b) and especially arbuscular mycorrhizas (AM), whose absorbing surface is much larger and of low cost to the plant…”
• 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).”
• Response and interaction of Bradyrhizobium japonicum and arbuscular mycorrhizal fungi in the soybean rhizosphere (2018, background): “Soybeans are shown to adapt to low P environments through various processes, such as changes in root characteristics (root length, root diameter, root hairs), association with mycorrhiza, and modification of the rhizosphere chemistry (Gahoonia and Nielsen 2004).”
• What is the significance of the arbuscular mycorrhizal colonisation of many economically important crop plants? (2011, background): “All of these factors have been extensively reviewed (e.g., Bolan 1991; Marschner and Dell 1994 ;M arschner1995; Gahoonia and Nielsen 2004; Smith and Read 2008; Smith et al. 2010).”
• Phosphorus benefits from grain-legume crops to subsequent maize grown on acid soils of southern Cameroon (2006, background): “Therefore, enhancing P transport and soil/root contact through lateral root formation (Lynch et al. 1997; Manske et al. 2000), root-hair length (Gahoonia and Nielsen 2004) and reduced root diameter (Föhse et al. 1991), or establishing a symbiosis with arbuscular mycorrhizal fungi which allows…”
• 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.”
• Influence of root and leaf traits on the uptake of nutrients in cover crops (2016, background): “Root hairs will also increase P acquisition capacity by expanding root area (Gahoonia and Nielsen 2004; Zhu et al. 2010).”
