Acquisition of phosphorus and other poorly mobile nutrients by roots. Where do plant nutrition models fail? (2011, background): “…biogeochemistry, via the physiology of plant roots, namely the exudation of protons, carboxylates or phosphatases (Hinsinger 2001; Neumann and Römheld 1999; Raghothama and Karthikeyan 2005; Richardson et al. 2000, 2001; Tang et al. 2004; Vance et al. 2003; Wissuwa 2003, 2005; Yan et al. 2004).”
Phosphatase and phytase activities in nodules of common bean genotypes at different levels of phosphorus supply (2008, background): “The low intrinsic levels of phytase activity in roots of wheat seedlings limited the ability of plants to obtain P from phytate in the growth medium (Richardson et al. 2000), and the phytase activity secreted by roots of tobacco (Nicotiana tabacum) seedlings under P stress seemed insufficient to…”
Dynamics of phosphorus fractions in the rhizosphere of common bean (Phaseolus vulgaris L.) and durum wheat (Triticum turgidum durum L.) grown in monocropping and intercropping systems (2008, background): “2007), and secretion of phosphatase (Li et al. 1997; Neumann et al. 2000; Richardson et al. 2000; George et al. 2004).”
Secretion of beta-propeller phytase from tobacco and Arabidopsis roots enhances phosphorus utilization (2005, background): “In some studies, a limited capacity to utilize phytic acid from external sources was observed for a range of plants, including Arabidopsis [17], wheat [12] and various forage species [11].”
Synergy between Plants and P-Solubilizing Microbes in soils: Effects on Growth and Physiology of Crops (2011, background): “Plants complete their phosphorous requirement by uptake of phosphate anions from the soil solution (Richardson et al., 2000).”
Recent advances in genetic transformation of forage and turf grasses (2006, background): “and phytase (Hayes et al., 1999; Wasaki et al., 1999; Richardson et al., 2000; Vance et al., 2003); however, it has been suggested that the activity of these enzymes in roots is inadequate for effective utilization of organic P (Hayes et al.”
Phytases and Phytase-Labile Organic Phosphorus in Manures and Soils (2013, background): “This hypothesis is supported by the increase of P acquisition in inoculation experiments (Richardson, 2001; Richardson et al., 2001a; Richardson et al., 2000; Tarafdar and Marschner, 1995) and microbial enzyme addition experiments (Findenegg and Nelemans, 1993; Hayes et al., 2000b).”
