ROOT STRATEGIES FOR PHOSPHORUS ACQUISITION (2008, background): “Overexpression of enzymes responsible for organic acid production in roots improves plant growth in soils with excess aluminum or low P availability (Koyama et al. 2000; Lopez-Bucio et al. 2000; Tesfaye et al. 2001).”
Plant and microbial strategies to improve the phosphorus efficiency of agriculture (2011, background): “…carboxylase (PEPC) resulted in enhanced efflux of a range of organic anions from roots of lucerne (alfalfa; Medicago sativa L.), and the enhanced P nutrition of the transgenic plants when grown on acid soil was attributed to the greater efflux of organic anions (Tesfaye et al. 2001).”
Molecular physiology of aluminum toxicity and tolerance in plants (2007, background): “In some cases, overexpression of genes encoding enzymes for organic acid synthesis has also proved to enhance aluminum tolerance (Tesfaye et al., 2001).”
Hydrolysis of precipitated phytate by three distinct families of phytases (2006, methodology): “Enhanced 7 secretion of organic acids has been accomplished by overexpression of malate 8 dehydrogenase (Tesfaye et al., 2001), citrate synthase (Koyama et al., 2000) and 9 malate transporter (Delhaize et al., 2004).”
The Physiology, Genetics and Molecular Biology of Plant Aluminum Resistance and Toxicity (2005, background): “, 2002); • Overexpression of genes encoding enzymes involved in organic acid synthesis, such as citrate synthase and malate dehydrogenase can, in some cases, result in enhanced Al resistance (de la Fuente et al., 1997; Koyama et al., 2000; Tesfaye et al., 2001); 179”
Plant improvement for tolerance to aluminum in acid soils – a review (2003, methodology): “When cultured in quartz sand, transgenic drogenase (MDH), has been investigated as a means lines containing the neMDH transgene exuded enof enhancing organic acid synthesis and Al tolerance hanced amounts of citrate, oxalate, malate, succinate (Tesfaye et al., 2001).”
Influence of enhanced malate dehydrogenase expression by alfalfa on diversity of rhizobacteria and soil nutrient availability (2003, unknown): “The transgenic alfalfa line M16-27 produced 7.1-fold increased organic acid exudation over untransformed alfalfa plants (Tesfaye et al., 2001).”
Strategies and methods for studying the rhizosphere—the plant science toolbox (2009, background): “Overexpression of MDH in lucerne increased the efflux of organic anions from roots, but over-expression of PEPC did not (Tesfaye et al. 2001).”
The Functional Organization and Control of Plant Respiration (2006, background): “In Al-toxic soils, root exudation of organic acids protects plants by chelating Al3+ ions in the rhizosphere, thus preventing their entry into the root cytoplasm (Ryan et al., 2001; Tesfaye et al., 2001).”
Malate plays a central role in plant nutrition (2002, background): “By comparison, MDH 20–10 plants also tended to exude more organic acids than the control but less than MDH 16–27 (Tesfaye et al., 2001).”
