Ecol Evol. A novel understanding of humus chemistry and implications in soil science. While the 1D 13C spectra of fresh plant tissues well differentiated the composition of fresh pine and grass materials, the differences became negligible after decomposition and suggested a similar accumulation of recalcitrant carbon species, thus again supporting a mechanism of progressive selection of hydrophobic degradation products regardless of the plant origin [21]. Metabolomic analysis at an early stage of regeneration. In particular, the authors used HRMAS to compare the metabolome of wild-type plants with that of transgenic T-35S plants carrying the VaP5CSF129A transgene encoding a mutated enzyme involved in proline biosynthesis. 2015;53:735–44.

Magn Reson Chem. Nevertheless, the use of liquid-state NMR spectroscopy for the molecular identification of agricultural matrices (plant roots, leaves and fruits, animal tissues, soils, etc.) Moreover, this study also highlighted the advantage of the use of diffusion-based filter to selectively identify and monitor the signals of fast-diffusing components developed during degradation process [22]. 1), which may not only further improve spectral resolution, but also select coherence pathways and permit diffusion experiments to differentiate molecular species according to their degree of mobility in hydrated matrices. Ritota et al. The HRMAS technique was further employed to identify the components of a peat humic acid mostly involved in the organomineral complexes with both kaolinite and montmorillonite clay minerals and how the interactions were influenced by both clay mineralogy and several solution properties, such as pH, ionic strength, and the presence of Na+ and Ca2+ cations [19]. Moreover, these authors inferred that α-branched fatty acids/esters in cutin could be cross-linked to esters of mid-chain hydroxyls [38]. Nuclear magnetic resonance (NMR) is a powerful technique for characterization of food products based on measuring the profile of metabolites. 2015;49:13983–91. Three spectral regions are shown: a 0.8–3.3 ppm, b 3.34–4.27 ppm, and c 4.4–9.25 ppm. PubMed  Practical Applications of NMR in Industry Conference (PANIC) was initiated to provide an interactive forum for discussion of the latest developments in the use of NMR for practical applications to real problems faced by scientists in industry and research institutions. When the sample rotates around an axis inclined of 54.7° to the magnetic field, all broadening factors are theoretically nulled [7, 8]. An asterisk (*) indicates that absolute quantification was not possible at these positions due to spectral overlap. Comprehensive multiphase NMR Spectroscopy of Intact 13C Labeled Seeds. They were successful to show the feasibility even at moderate magnetic fields of NMR detection in bacterial cells of an unlabeled metabolite at a pharmacologically relevant (i.e., submillimolar) concentration [79].

Cade-Menun provided an essential overview of the most important studies on the application of solution-state 31 P NMR spectroscopy for the characterization and quantification of P forms in non-pasture cropland soils. In particular, tomato cutin was shown to contain a structural skeleton composed predominantly by an aliphatic polyester with some olefinic and aromatic moieties [38]. Zalesskiy SS, Danieli E, Blümich B, Ananikov VP. A HRMAS investigation on organomineral complexes obtained by coating either montmorillonite or kaolinite clays by peat humic acids showed that these humic-clay complexes, especially in acidic conditions, were responsible for the increasing sorption of the non-ionic and hydrophobic phenanthrene contaminant [19]. Kelleher BP, Simpson MJ, Simpson AJ. Both 1H and 31P HRMAS NMR spectra were used to elucidate the granule hydration in either wheat- or maize-derived starches at different temperatures [70]. 2011;59:12784–93. PubMed Google Scholar. Biochem Biophys Res Commun. The HRMAS technique has been also applied to evaluate transgenic plants. Moreover, HRMAS allows us to use edited pulse sequences which, especially in the case of biological tissues or agrofood products, may provide a simultaneous information on polar and non-polar components without the need of preliminary sample extraction. The same authors observed that the detection of aromatic signals may be significantly enhanced when the soil is swollen in dimethylsulfoxide (DMSO) rather than in water. The adsorbed or intercalated forms of herbicide 4-chloro-2-methylphenoxyacetic acid on a highly hydrated clay, such as hydrotalcite, were clearly distinguished by 1H-HRMAS. These extensive spectral-broadening interactions are described in a Hamiltonian that contains an angular dependence of (3cos2 The presumed beneficial role exerted by humic acids in plant regeneration was verified by HRMAS on root and shoot calli explanted by pear and quince plants, after treatments with different concentrations of peat humic acids [45].

AU - Schmidt, S. J. Due to its capacity to produce meaningful spectra of semi-solid and fresh samples, HRMAS represents an eligible technique to perform in vivo analysis of living micro- and macroorganisms. Biol Fertil Soils. HRMAS results were also determinant to show that conventional and organic management treatments affect differently the composition of fresh olive fruits [37]. The advanced NMR pulse sequence STDD (saturation transfer double difference) was used to prove the pH-dependent (D2O or sodium phosphate D2O buffer solution at pH7) interactions between a peat soil and several contaminants, including 1-naphthol and the pesticides trifluralin, acifluorfen, and 4-nitro-3-(trifluoromethyl) phenol [31]. Such finding was accompanied by a further study in which diffusion-edited HRMAS NMR spectra of HF-treated soil aggregates of different dimensions were related to the role of microbes in conservation tillage systems [27]. Recently, Mazzei and coworkers applied 1H HRMAS metabolomics to identify the effects on young Solanum lycopersicum (tomato) plants of seeds treatment with two bioactive secondary metabolites (6-pentyl-2H-pyran-2-one and harzianic acid) extracted from different trichoderma fungal strains [14]. Despite that most of HRMAS applications had been focusing on biomedical studies and materials chemistry [7, 13, 14], a body of literature has already pointed out that HRMAS may result determinant in investigations related to agricultural issues.

The HRMAS technique has been successfully applied to follow the effects of inorganic and organic contaminants in biological tissues. Moreover, an HRMAS approach was recently exploited to distinguish waxy from non-waxy Chinese rice grains, deriving from different Oryza sativa L. cultivars [69]. The high resolution of HRMAS spectra is due to the reduction of H–H dipolar couplings to few hundred Hz in many semi-solid samples, in respect to the 20–50 kHz usually found for rigid solid materials. Conceptually, the NMR phenomenon occurs when nuclei of magnetically active (spin number ≠ 0) atoms are immersed in a static magnetic field and exposed to a second oscillating magnetic field. [Figure reprinted with permission from Mazzei & Piccolo, Copyright 2012 by Food Chem. By comparing HRMAS results with those of ethanol extracts of the same petals analyzed by liquid-state NMR, it was observed that extraction favored hydrolysis reactions, thus decreasing the reliability of NMR results in the liquid-state. 1996;68:3370–6.
