Some rhizobia can convert insoluble P into available forms for plant growth but the underlying mechanisms for this are not understood. In this study, the function of rhizobia in P acquisition from P sources for soybean was studied. Four rhizobial strains were employed to evaluate their phosphate-solubilizing (PS) activity, their ability to mediate pH changes in growth medium for different P sources, and IAA production A sand culture experiment using different P sources was carried out to characterize P acquisition changes of soybean plants with or without rhizobium inoculation. Rhizospheric acidification in soybean was further analyzed in hydroponics. Our results showed that all the tested rhizobial strains exhibited significant PS activity for different P sources in the order of Ca-P>Al-P>Phy-P≥Fe-P as indicated by the halo/colony ratio technique and increased Pi percentage in the solid and liquid phases, resp. Furthermore, all of the rhizobial strains could acidify the growth medium for all P sources except Phy-P, but only three of them produced IAA. Compared to non-nodulated plants, the nodulated plants had greater plant biomass and P content in sand culture for all the tested P sources, especially for Ca-P. Moreover, H⁺ and total acid exudation was more significantly enhanced in the nodulated plants in hydroponics. Conclusions Our results suggested that the PS ability of rhizobia is more related to acidification of the growth medium than IAA production Rhizobium inoculation could enhance P acquisition in soybean, especially on soils where Ca-P is the primary P source, and the primary mechanism for rhizobial-mediated P solubilization appears to be via Pi remobilization of nodulated roots through rhizospheric acidification.

Sala, Martin;Makuc, Damjan;Kolar, Jana;Plavec, Janez;Pihlar, Boris published 《Potentiometric and ³¹P NMR studies on inositol phosphates and their interaction with iron(III) ions》 in 2011.

They have made some progress in their research.Reference of rel-(1R,2r,3S,4R,5s,6S)-Cyclohexane-1,2,3,4,5,6-hexayl hexakis(dihydrogen phosphate), dipotassium salt The article mentions the following:

Potentiometric, conductometric and ³¹P NMR titrations have been applied to study interactions between myo-inositol hexakisphosphate (phytic acid), (±)-myo-inositol 1,2,3,5-tetrakisphosphate and (±)-myo-inositol 1,2,3-trisphosphate with iron(III) ions. Potentiometric and conductometric titrations of myo-inositol phosphates show that addition of iron increases acidity and consumption of hydroxide titrant. By increasing the Fe(III)/InsP₆ ratio (from 0.5 to 4) 3 mol of protons are released per 2 mol of iron(III). At first, phytates coordinate iron octahedrally between P2 and P1,3. The second coordination site represents P5 and neighboring P4,6 phosphate groups. Complexation is accompanied with the deprotonation of P1,3 and P4,6 phosphate oxygens. At higher concentration of iron(III) intermol. P-O-Fe-O-P bonds trigger formation of a polymeric network and precipitation of the amorphous Fe(III)-InsP₆ aggregates. ³¹P NMR titration data complement the above results and display the largest chem. shift changes at pD values between 5 and 10 in agreement with strong interactions between iron and myo-inositol phosphates. The differences in T₁ relaxation times of phosphorous atoms have shown that phosphate groups at positions 1, 2 and 3 are complexated with iron(III). The interactions between iron(III) ions and inositol phosphates depend significantly on the metal to ligand ratio and an attempt to coordinate more than two irons per InsP₆ mol. results in an unstable heterogeneous system.

Feng, Xionghan;Yan, Yupeng;Wan, Biao;Li, Wei;Jaisi, Deb P.;Zheng, Lirong;Zhang, Jing;Liu, Fan published 《Enhanced Dissolution and Transformation of ZnO Nanoparticles: The Role of Inositol Hexakisphosphate》. The research results were published in《Environmental Science & Technology》 in 2016.Name: rel-(1R,2r,3S,4R,5s,6S)-Cyclohexane-1,2,3,4,5,6-hexayl hexakis(dihydrogen phosphate), dipotassium salt The article conveys some information:

The toxicity, reactivity, and behavior of ZnO nanoparticles (NPs) released in the environment highly depend on environmental conditions. Myo-inositol hexakisphosphate (IHP), a common organic phosphate, may interact with NPs and generate new transformation products. Here, the role of IHP in mediating the dissolution and transformation of ZnO NPs was studied in the laboratory kinetic experiments using powder x-ray diffraction, attenuated total reflectance FTIR spectroscopy, ³¹P NMR spectroscopy, high-resolution transmission electronic microscopy, and synchrotron-based extended x-ray absorption fine structure spectroscopy. The results indicate that IHP shows a dissolution-precipitation effect, which is different from citrate and EDTA that only enhances Zn dissolution The enhanced dissolution and transformation of ZnO NPs by IHP (<0.5 h) is strikingly faster than that induced by inorganic phosphate (Pi, >3.0 h) at pH 7.0, and the reaction rate increases with decreasing pH and increasing IHP concentration Multitechnique analyses reveal that interaction of ZnO NPs with IHP induces rapid transformation of ZnO NPs into Zn phytate complexes initially and poorly crystalline Zn phytate-like (Zn-IHP) phase finally. ZnO NPs preferentially react with IHP and transform to Zn-IHP when Pi and IHP concurrently coexist in a system. Overall, results from this study contribute to an improved understanding of the role of organic phosphates (e.g., IHP) in the speciation and structural transformation of ZnO NPs, which can be leveraged for remediation of ZnO-polluted water and soils.

Electric Literature of C6H18K2O24P6《Synthesis, solid-state characterization and solution studies of new phytate compounds with Cu(II) and 1,10-phenanthroline: progress in the structural elucidation of phytate coordinating ability》 was published in 2016. The authors were Quinone, D.;Veiga, N.;Torres, J.;Castiglioni, J.;Bazzicalupi, C.;Bianchi, A.;Kremer, C., and the article was included in《Dalton Transactions》. The author mentioned the following in the article:

Within all the eukaryotic cells there is an important group of biomols. that was potentially related to signalling functions: myo-inositol phosphates (InsP_s). In nature, the most abundant member of this family is the so called phytate (InsP₆, L^12-). The importance of the interaction of InsP₆ with cations was recognized during the last few years, and any attempt to know the function of this mol. in eukaryotic cells must include the fact that InsP₆ will be strongly associated with simple inorganic or organic ammonium cations. The authors expand on the authors’ earlier findings by studying the systems phen-phytate (phen = 1,10-phenanthroline) and Cu(II)-phen-phytate. The structures of (Hphen)₄(H₈L)·7.5H₂O and [Cu₅(H₇L)₂(H₂O)₂(phen)₅]·23H₂O are presented. Solution studies of the binary and ternary systems were also performed by potentiometric titrations at 37.0° and 0.15M ionic strength. The work was completed with a mol. modeling study. All this information is essential in the process of gaining reliable structural knowledge about the most important InsP₆ species in the in vitro and in vivo experiments, and how these features modulate their probable biol. functions.
