Acquisition of phosphorus and nitrogen in the rhizosphere and plant growth promotion by microorganisms (2009, background): “Indeed identification of germplasm and its use in breeding programs that are directed at modifications to root architecture have been successful in improving nutrient efficiency under field conditions through either direct plant selection (Gahoonia et al. 1999; Liao et al. 2006; Lynch and Brown 2001”
Genotypic variation in seedling root architectural traits and implications for drought adaptation in wheat (Triticum aestivum L.) (2008, background): “Substantial variation in root architecture has been reported both among plant species (Kutschera 1960; Fitter and Stickland 1992; Bouma et al. 2001), and within genotypes of crop species (Masi and Maranville 1998 ;L iao et al.2001; Lynch and Brown 2001; McPhee 2005) including wheat (Manschadi et a”
Phosphorus acquisition characteristics of cotton (Gossypium hirsutum L.), wheat (Triticum aestivum L.) and white lupin (Lupinus albus L.) under P deficient conditions (2008, background): “The level of increase (15%) coincided with the values reported by Maqsood et al. (2005) for this species.”
Architectural Tradeoffs between Adventitious and Basal Roots for Phosphorus Acquisition (2005, background): “…stratified with depth, which is common for many reasons including bioaccumulation, higher microbial activity near the surface and fertilization of agricultural soils (Lynch and Brown, 2001), then plants are expected to benefit from adventitious root proliferation, regardless of phosphorus mobility.”
Regulation and function of root exudates. (2008, background): “The root system plays a big role in acquisition of resources in a natural heterogeneous soil environment (Lynch & Brown 2001).”
Roots of the Second Green Revolution (2007, background): “Because the topsoil is generally the soil stratum with the greatest phosphorus bioavailability, the extent of topsoil foraging is an important aspect of phosphorus acquisition in most soils (Lynch and Brown 2001).”
Plant root growth, architecture and function (2009, background): “The influence of tropisms varies among root branching order or adventitious/ seminal roots (Lynch and Brown 2001).”
Root structure and functioning for efficient acquisition of phosphorus: Matching morphological and physiological traits. (2006, background): “In terms of P nutrition, the root architecture of Phaseolus vulgaris when grown at low Pi supply is significant for immobile nutrients such as P because more laterals are produced in shallow soil horizons, where most of the P is located (Lynch and Brown, 2001).”
Management of soil phosphorus and plant adaptation mechanisms to phosphorus stress for sustainable crop production: a review (2012, positive): “…that have highly branched root systems and more root apices are efficient in acquiring P. Additionally, P-efficient genotypes also grow lateral roots from the basal roots at an angle that enables them to better explore the upper layers of the soil relatively rich in P (Lynch and Brown, 2001).”
