Plant and microbial strategies to improve the phosphorus efficiency of agriculture (2011, background): “Root architectural traits, themselves, may interact to alter the extent of inter-root competition, which is an important component of overall root foraging efficiency (Ge et al. 2000; Rubio et al. 2003; Rubio et al. 2001; Walk et al. 2006).”
Architectural Tradeoffs between Adventitious and Basal Roots for Phosphorus Acquisition (2005, methodology): “…relative competition is Cr ¼ 100ðVt VaÞ=Va: ð5Þ Simulated phosphorus acquisition was calculated by multiplying depletion volume by empirically determined factors to account for phosphorus concentration and soil buffering of phosphorus as previously reported (Ge et al., 2000; Rubio et al., 2001).”
ROOT STRATEGIES FOR PHOSPHORUS ACQUISITION (2008, background): “Geometric modeling suggests that root architecture can alter the C cost of soil exploration by regulating the extent of root competition within and among root systems (Ge et al. 2000; Rubio et al. 2001).”
Rhizoeconomics: Carbon costs of phosphorus acquisition (2005, methodology): “This results from the colocalization of root foraging with phosphorus availability as well as reduced competition among roots of the same (Ge et al., 2000) or neighboring (Rubio et al., 2001) plants.”
Lack of relationship between below‐ground competition and allocation to roots in 10 grassland species (2003, background): “…2003 British Ecological Society, Journal of Ecology, 91, 532–540 been suggested or demonstrated to influence belowground competitive ability, including (but not limited to) root proliferation (Robinson et al. 1999), root architecture (Rubio et al. 2001), and uptake kinetics (Caldwell et al. 1991).”
Modelling the rhizosphere: a review of methods for ‘upscaling’ to the whole‐plant scale (2006, background): “In a second study, Ge et al. modified SimRoot to allow multiple root systems sharing the same soil domain to be simulated (Rubio et al., 2001) and concluded that competition between roots from different plants was always more intense than competition between roots of the same plant with the same…”
Mechanisms for Dominance in An Early Successional Old Field by the Invasive Non-Native Lespedeza Cuneata (Dum. Cours.) G. Don (2004, background): “As seen in the shade plots, species with differing spatial niches or contrasting root architecture may reduce the extent of root competition among neighboring plants (Rubio et al. 2001).”
Roots of the Second Green Revolution (2007, background): “…bean genotypes with shallow basal roots outcompete genotypes with deep basal roots in low-phosphorus fields (Rubio et al. 2003), because of enhanced topsoil exploitation and reduced competition (i.e. reduced overlap of phosphorus-depletion zones) among roots of the same plant (Rubio et al. 2001).”
Mineral stress: the missing link in understanding how global climate change will affect plants in real world soils (2004, background): “…horizons, such as phosphorus, versus those that may be found at greater depth, such as nitrogen, and whether greater root densities in a specific soil horizon result in greater soil exploration or merely greater inter-root competition (Ge et al., 2000; Lynch and Brown, 2001; Rubio et al., 2001).”
