“…Root APase activity increases dramatically in P‐deficient white lupin plants (Ozawa et al ., 1995; Gilbert et al ., 1999). This large increase in APase activity is associated with the appearance of a novel isoform (Wasaki et al ., 1997; Gilbert et al ., 1999). Moreover, this novel form induced by P‐stress is also secreted into the rhizosphere of cluster roots (Gilbert et al ., 1999; Miller et al ., 2001; Wasaki et al ., 2002).…”

Contents Introduction 424 The phosphorus conundrum 424 Adaptations to low P 424 Uptake of P 424 P deficiency alters root development and function 426 P deficiency modifies carbon metabolism 431 Acid phosphatase 436 Genetic regulation of P responsive genes 437 Improving P acquisition 439 Synopsis 440 Summary Phosphorus (P) is limiting for crop yield on > 30% of the world's arable land and, by some estimates, world resources of inexpensive P may be depleted by 2050. Improvement of P acquisition and use by plants is critical for economic, humanitarian and environmental reasons. Plants have evolved a diverse array of strategies to obtain adequate P under limiting conditions, including modifications to root architecture, carbon metabolism and membrane structure, exudation of low molecular weight organic acids, protons and enzymes, and enhanced expression of the numerous genes involved in low‐P adaptation. These adaptations may be less pronounced in mycorrhizal‐associated plants. The formation of cluster roots under P‐stress by the nonmycorrhizal species white lupin (Lupinus albus), and the accompanying biochemical changes exemplify many of the plant adaptations that enhance P acquisition and use. Physiological, biochemical, and molecular studies of white lupin and other species response to P‐deficiency have identified targets that may be useful for plant improvement. Genomic approaches involving identification of expressed sequence tags (ESTs) found under low‐P stress may also yield target sites for plant improvement. Interdisciplinary studies uniting plant breeding, biochemistry, soil science, and genetics under the large umbrella of genomics are prerequisite for rapid progress in improving nutrient acquisition and use in plants.

“…Duff et al (1991) used antibodies to demonstrate that P deprivation induced de novo synthesis of a cell wall nonspecific APase. Wasaki et al (1997) used antibodies against a secreted APase to localize this protein in lupin roots on epidermal cell surfaces of the main tap root as well as in the cell walls and intercellular spaces of lateral roots.

The tendency of phosphorus (P) to undergo adsorption and precipitation reactions in soil makes it one of the most immobile of the essential plant nutrients. As a result, the concentration of available P in soil solution is usually very low even though the total P content of soils is generally high. Consequently, P is second only to N in limiting crop productivity. In areas of the world such as the North America and Europe in which P fertilizers are applied liberally to agricultural fields, the loss of this nutrient through its transport in particulate and soluble forms from agricultural fields to lakes and rivers is of concern due to accelerated eutrophication. The need to provide crops with adequate P combined with the desire to minimize the adverse effect of P on the environment will 1101 ORDER REPRINTS require strategies to reduce P inputs and to maximize the efficiency of P uptake mechanisms in plants. Recent advances in molecular biology offer opportunities to manipulate plants to increase uptake efficiencies of P. Integration of arbuscular mycorrhizal fungi into cropping systems provides an alternative means of maintaining yields while reducing P inputs. To realize the potential of these new technologies, however, a thorough understanding of both soil and plant factors involved in P uptake, and the effects of cultural practices on arbuscular mycorrhizal associations are needed. A review of the literature was undertaken to summarize the relevant state of knowledge on P uptake processes in plants and the mechanisms by which P uptake efficiencies could be enhanced, with particular emphasis on arbuscular mycorrhizal fungi. 1102 MIYASAKA AND HABTE Downloaded by [University of Colorado at Boulder Libraries] at 20:55 25 December 2014 ORDER REPRINTS Water QualityAccelerated eutrophication of lakes and streams in the United States has been attributed primarily to non-point source pollution of P from agriculture (Daniel et al., 1998;Mathews et al., 1998). From cultivated lands, a major proportion of P is transported as particulate P associated with soil particles or organic matter during erosion events (Sharpley et al., 1992). From grasslands, forests, or non-erosive soils, P in runoff is predominantly soluble P (Daniel et al., 1998;Sharpley et al., 1992).Plants can be a critical component in reducing P loss from agricultural soils, by providing plant cover to prevent erosion, or by taking up P i from soil solutions and reducing its concentration. Thus, it is important to understand the processes by which plants take up, regulate, and transport P within the plant, and the various plant mechanisms and mycorrhizal symbioses that can increase P uptake efficiency. The objective of this review is to discuss the current state of knowledge PHOSPHORUS UPTAKE EFFICIENCY 1103 Downloaded by [University of Colorado at Boulder Libraries] at 20:55 25 December 2014 ORDER REPRINTSabout plant uptake of P and mechanisms to increase P uptake efficiencies, in particular the impacts of vesicular arbuscular mycorrhizas.

“…The expression of APase genes is affected by different environmental factors [73]. Reviewing the previous literature, there are several studies reporting that the activity of phosphatase acids can be enhanced under P deficiency in green beans [74], as well as in other crops such as lupinus [75], white clover [76], and wheat [77]. Nevertheless, our results reveal that under increasing P supply to green beans, the activity of phosphatase acid decreased in the different organs assessed.…”

Phosphorus and Carbohydrate Metabolism in Green Bean Plants Subjected to Increasing Phosphorus Concentration in the Nutrient Solution

Phosphorus (P) is considered an elementary mineral nutrient for plants. Nevertheless, excessive or deficit supply to the crop may cause negative changes at the physiological level. Plants were cultivated in pots in a growth chamber under increasing P concentration (P1 (0.5 mmol/L (control treatment)), P2 (1 mmol/L); P3 (2 mmol/L); P4 (4 mmol/L); P5 (6 mmol/L), and P6 (8 mmol/L)) in the nutrient solution for 40 days. At the end of the experimental period, biomass, carbohydrates concentration, and enzymatic activities related to the synthesis and degradation of sucrose as well as the different fractions of P in different organs of the plant were assessed. The results obtained in this experiment reveal a decrease in biomass under increasing P supply. Fructose, glucose, sucrose, and starch concentrations were higher in the shoots compared to the roots. There were different trends in the roots and shoots in enzymatic activities related to sucrose. The increase in P dose increased the concentration of the different forms assessed for P in all the organs studied. Seed phytate concentration surpassed the threshold established by the Food and Agriculture Organization (FAO) for green bean plants grown under P4, P5, and P6 treatments. Considering the results obtained, we suggest fertigation with a concentration of 2 mmol/L to obtain a higher productivity without excess of phytate in seeds.
