Root structure and functioning for efficient acquisition of phosphorus: Matching morphological and physiological traits. (2006, background): “A. thaliana transformed with heterologous phytase secreted the enzyme only from roots when grown on medium containing low Pi concentrations, enabling growth on phytate as a sole P source (Mudge et al., 2003).”
Phytases and Phytase-Labile Organic Phosphorus in Manures and Soils (2013, background): “Under sterile growth conditions, these transgenic plants were able to use phytate as P source (George et al., 2004; Mudge et al., 2003; Richardson et al., 2001b; Richardson et al., 2001c; Zimmermann et al., 2003).”
Phytase for food application (2006, background): “In addition, the introduction and expression of microbial phytase-encoding genes into several different plants including tobacco (131–136), alfalfa (137), arabidopsis (43,135,138,139), subterranean clover (140), sesame (141), soybean (142), canola (143), potato (144,145), rice (42,146–148), wheat (1”
Strategies and methods for studying the rhizosphere—the plant science toolbox (2009, background): “It was demonstrated that transgenic plants which release extracellular phytase to the rhizosphere had a novel ability to mineralise and utilise P from inositol phosphates and, when grown under controlled conditions, showed enhanced growth and P nutrition (George et al. 2004; Richardson et al. 2001; ”
Enzymes of importance to rhizosphere processes (2015, background): “Similar results were obtained with transgenic Arabidopsis (Mudge et al., 2003).”
Developments in biochemical aspects and biotechnological applications of microbial phytases (2011, background): “only from roots when grown on a medium under low phosphate conditions (Mudge et al., 2003).”
Recent advances in genetic transformation of forage and turf grasses (2006, background): “Ectopic expression of a fungal phytase gene or a fungal-based synthetic phytase gene resulted in increased P acquisition and biomass production in transgenic Arabidopsis and potato plants (Richardson et al., 2001; Mudge et al., 2003; Zimmermann et al., 2003).”
Functional biology of plant phosphate uptake at root and mycorrhiza interfaces. (2007, background): “The latter hypothesis does not contradict the data of Mitsukawa and colleagues, and is supported by studies on the engineering of root secretory processes where enhanced secretion of acid phosphatases (phytases) and organic acids was shown to improve plant P nutrition in low-P conditions via an incr”
Microbial phytase activity and their role in organic P mineralization (2015, background): “In many soils, 30–80% of organic P is present, but not properly utilized by plants due to P immobilization (Mudge et al. 2003; Menezes-Blackburn et al. 2013).”
Feeding hungry plants: The role of purple acid phosphatases in phosphate nutrition (2010, background): “to Pi starvation, each appears to have a certain degree of tissuespecific expression, with some expressed in epidermal and root hair cells while others are expressed in stelar cells of the root [35].”
