“…1). The latter is in agreement with numerous studies that have reported the negative effects of P starvation on N 2 -fixing capacity of legumes (Jakobsen, 1985;Israel, 1987;Sa and Israel, 1991;Al-Niemi et al, 1997;Vadez et al, 1997;Tang et al, 2001Tang et al, , 2004Olivera et al, 2004;Le Roux et al, 2008). Israel (1987) has postulated that P has specific roles in nodule initiation, growth, and functioning in addition to its involvement in host plant growth processes.…”

“…The deleterious effect of P deficiency on SNF and plant growth has been evidenced through the evaluation of physiological and biochemical parameters, such as nodule number and mass, nitrogenase and carbon/N assimilatory enzyme activities, CO 2 fixation, photosynthesis, energy status, organic acid synthesis, release of protons or organic acids, and nodule O 2 diffusion. Such studies have been performed in different legume species such as lupin, soybean, alfalfa (Medicago sativa), white clover (Trifolium repens), Medicago truncatula, pea (Pisum sativum), and common bean (Phaseolus vulgaris;Jakobsen, 1985;Israel, 1987;Sa and Israel, 1991;Drevon, 1995a, 1995b;Al-Niemi et al, 1997;Vadez et al, 1997;Almeida et al, 2000;Tang et al, 2001Tang et al, , 2004Hogh-Jensen et al, 2002;Olivera et al, 2004;Schulze and Drevon, 2005;Schulze et al, 2006;Le Roux et al, 2008).…”

“…Bean genotypes differ in N 2 fixation ability and P use efficiency under P deficiency. Considering the greater P need of nodulated legumes, P-tolerant cultivars that in addition partition a significant percentage of their P uptake to nodules will be a prerequisite for improved bean N 2 fixation (Graham, 1981;Broughton et al, 2003;Graham et al, 2003;Tang et al, 2004).…”

Phosphorus (P) deficiency is widespread in regions where the common bean (Phaseolus vulgaris), the most important legume for human consumption, is produced, and it is perhaps the factor that most limits nitrogen fixation. Global gene expression and metabolome approaches were used to investigate the responses of nodules from common bean plants inoculated with Rhizobium tropici CIAT899 grown under P-deficient and P-sufficient conditions. P-deficient inoculated plants showed drastic reduction in nodulation and nitrogenase activity as determined by acetylene reduction assay. Nodule transcript profiling was performed through hybridization of nylon filter arrays spotted with cDNAs, approximately 4,000 unigene set, from the nodule and P-deficient root library. A total of 459 genes, representing different biological processes according to updated annotation using the UniProt Knowledgebase database, showed significant differential expression in response to P: 59% of these were induced in P-deficient nodules. The expression platform for transcription factor genes based in quantitative reverse transcriptase-polymerase chain reaction revealed that 37 transcription factor genes were differentially expressed in P-deficient nodules and only one gene was repressed. Data from nontargeted metabolic profiles indicated that amino acids and other nitrogen metabolites were decreased, while organic and polyhydroxy acids were accumulated, in P-deficient nodules. Bioinformatics analyses using MapMan and PathExpress software tools, customized to common bean, were utilized for the analysis of global changes in gene expression that affected overall metabolism. Glycolysis and glycerolipid metabolism, and starch and Suc metabolism, were identified among the pathways significantly induced or repressed in P-deficient nodules, respectively.A key to the success of the legume family, which comprises approximately 700 genera with more than 18,000 species (Doyle and Luckow, 2003), was the evolution of mutualistic symbioses with nitrogen (N)-fixing bacteria of the family Rhizobiaceae to directly capture atmospheric dinitrogen (N 2 ) to support plant growth. Symbiotic nitrogen fixation (SNF) takes place in specialized rhizobia-induced legume root nodules and involves a tight association between the two symbionts. SNF and legume crop production might be affected by disease and insect pressures but also by edaphic constraints that include climatic conditions, nutrient deficiency, soil acidity, and metal toxicity.Phosphorus (P) is an essential macronutrient for plant growth and development, with P concentration ranging from 0.05% to 0.5% plant dry weight. P is taken by the plants as phosphate (P i ), but P i is unevenly distributed and relatively immobile in soils. As

BAT477 is an advanced line from CIAT derived from the cross (G 3834×G 4493)×(G 4792×G 5694) and was selected for its growth and nitrogen fixation capacity in symbiosis with Rhizobium under P-deficient and drought stress conditions (Lynch and White 1992;Tang et al 2004;Jebara et al 2005) Plant hydroponic growth conditions A hydroponic system with a perlite-matrix was used to grow bean plants under low and high P conditions in the greenhouse in 1.2l pots filled with perlite and moistened with 250 ml of nitrogen-free medium.

Physiological and genetic analysis of root responsiveness to auxin-producing plant growth-promoting bacteria in common bean (Phaseolus vulgaris L.)

et al. 2007

Plant root development can be largely affected through the association of roots with plant growth-promoting rhizobacteria (PGPR). However, little is known about the identity of plant genes enabling such PGPR-plant root associations. Differences in the responsiveness to PGPR among cultivars suggest genetic variation for this trait within germplasm. In this study, two genotypes of common bean (Phaseolus vulgaris L.), BAT477 and DOR364, were identified showing contrasting responsiveness in root development to inoculation with the PGPR Azospirillum brasilense Sp245. Inoculation with an A. brasilense Sp245 mutant strain strongly reduced in auxin biosynthesis or addition of increasing concentrations of exogenous auxin to the plant growth medium, indicated that the differential response to A. brasilense Sp245 among the bean genotypes is related to a differential response to the bacterial produced auxin. To further assess the role of the plant host in root responsiveness, a population of Recombinant Inbred Lines (RILs) of the DOR364×BAT477 cross was used to evaluate the efficacy of exogenous auxin on root development. We detected significant phenotypic variation among the RILs for basal root formation during germination upon addition of auxin to the growth medium. Genetic analysis revealed two quantitative trait loci (QTLs) associated with basal root responsiveness to auxin of which one explained 36% of the phenotypic variation among the RILs. This latter QTL mapped to the same location as a QTL for root tip formation at low P, suggesting that the host effect on root responsiveness to IAA interacts with specific root development. Also, significant correlations between basal root responsiveness to auxin and growth, root tips and root dry weight at low P were identified. To our knowledge, this is the first report on QTL detection for root responsiveness to auxin.

“…Phosphorus deficiency is thus one of the major yield-limiting nutrition problems for plants, especially in both acidic and calcareous soils where P retention is maximal (Barber 1984;Marschner 1995;Hinsinger 2001). Plant species have evolved various adaptations to acquire soil P (see reviews by Hinsinger 2001;Raghothama 1999;Raghothama and Karthikeyan 2005;Vance et al 2003), such as rhizosphere acidification (Hinsinger et al 2003;Neumann and Römheld 1999;Tang et al 2004;Shen et al 2004), exudation of carboxylates (Dinkelaker et al 1989;Jones 1998;Neumann and Römheld 1999;Ryan et al 2001;Shen et al 2003Shen et al , 2005Wang et al 2007), and secretion of phosphatase (Li et al 1997;Neumann et al 2000;Richardson et al 2000;George et al 2004). Plant species do not all show the same adaptations, and thus differ in the pools of soil P they can access to.…”

The main objective of the present study was to investigate phosphorus (P) dynamics in the rhizosphere of durum wheat (Triticum turgidum durum L.) and common bean (Phaseolus vulgaris L.) grown in monocropping and intercropping systems with nitrate supply. Wheat and common bean were grown either alone or in association in a cropping device with a thin (1 mm) soil layer sandwiched between large root mats. Wheat intercropped with common bean exhibited a 33% increase in shoot biomass and a 22% increased root biomass, without significantly affecting common bean growth. After 12 days of culture, rhizosphere pH decreased by 1.66 and 1.13 units in monocropping system of common bean and intercropping system, respectively. Wheat increased intercropped common bean proton release by 36% compared with monocropped beans. Common bean and wheat exhibited different behaviors in rhizosphere P dynamics. Monocropped wheat decreased Resin-P, NaHCO 3 -P and NaOH-P in its rhizosphere by 24, 96 and 10%, respectively. However, NaHCO 3 -P and NaOH-P were increased by 61 and 10% in the rhizosphere of intercropping. Almost all values about P fraction in intercropping system were between those in monocropped common bean and monocropped wheat. Through taping different P fraction, different plants species possibly can alleviate competition for phosphorus in intercropping system.
