This study is useful in the farming, fishery, poultry, sericulture, beekeeping and many more. They focused on the biocontrol of yeast Pichia anomala J121 and verified how their intracellular metabolites varied as a function of an induced oxygen limitation. J Agric Food Chem. R) around an axis inclined of an angle of 54.7° (the so-called “magic angle”) to the static magnetic field (B 2013;61:11201–11. In fact, these samples maintain a sufficient degree of molecular mobility to afford an efficient minimization of factors that affect NMR measurements of solid materials. 2015;176:278–87. Biochem Biophys Res Commun. 1996;118(51):13085–6. Food Chem.  |  1H HRMAS NMR spectra were successfully combined with the Batch Processing multivariate approach in order to model and interpret differences between wild-type and PttMYB76-modified poplar plants, while monitoring the time- or growth-related metabolic fluctuations in poplar plants [48]. Another study combined HRMAS and DRIFT (Diffuse reflectance infrared Fourier transform spectroscopy) techniques to identify the relationship between the structure of soil humic substances and long-term (40 years) soil management practices, including organic and/or mineral fertilizations [25].

Assessment of a 1H high-resolution magic angle spinning NMR spectroscopy procedure for free sugars quantification in intact plant tissue. Magn Reson Chem. J Agric Food Chem. 2015;53:667–78. Later, the same authors adopted a similar analytical approach to identify the structure of cutan and a cutin/cutan mixture from the Agave americana leaf cuticle [39]. HR-MAS NMR represents a powerful and versatile spectroscopic technique, enabling the molecular evaluation of samples (in semi-solid state) of agricultural concern, such as plant tissues, soil components, vegetables, and agro-food products, as well as it permits the acquisition of multidimensional and multinuclear NMR spectra to be potentially combined with mathematical and computational exercises, including multivariate statistical analyses.

This work also showed that the biomass degradation pathways are similar to those of plant material under similar degrading conditions, thus suggesting that the difference between recalcitrant carbon from different sources is negligible after decomposition. 13C–NMR spectra of humic substances extracted with different mechanisms. 2007 Nov-Dec;68(22-24):2799-815. doi: 10.1016/j.phytochem.2007.09.028.

Advances of high-resolution NMR techniques in the structural and metabolic analysis of plant biochemistry. Hence, this review aims to report on the most interesting applications of HRMAS NMR in agricultural chemistry. Lam L, Soong R, Sutrisno A, de Visser R, Simpson MJ, Wheeler HL, et al. The authors agreed to keep the copyright rule. Iglesias MJ, García-López J, Collados-Luján JF, López-Ortiz F, Díaz M, Toresano F, et al. This work showed that the metabolomic approach developed by HRMAS enabled the detection of the significant changes in phenolic compounds contained in As-treated plants. 2003;37:337–42. The figure shows the disposition of both RF solenoid and gradient coils as well as indicates the inclination of rotation axis at the magic angle (θ = 54.7°) in respect of static magnetic field (B Magn Reson Chem. In fact, the still significant segmental molecular motions in semi-solid matter allow the MAS system to efficiently minimize dipolar couplings [8]. 2015;49:13983–91.

Recently, this study was extended by exploiting results from diffusion, relaxation, cross polarization, and saturation transfer difference NMR experiments, which permitted to follow the sequestration of contaminants from the liquid phase into the whole soil [32]. Enhance growth The biochemistry can help the farmer to enhance their plant growt… Levitt M. Spin dynamics: basics of nuclear magnetic resonance. The emphasis is the practicality of the solution and “getting the job done”. HRMAS NMR spectroscopy was also applied in environmental chemistry studies, such as the interactions between a pesticide and soil mineral components. Alves Filho EG, Silva LMA, Choze R, Lião LM, Honda NK, Alcantara GB. Prevent Diseases The concept of the biochemistry can be used to create the best prevention method to the diseases. 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]. The authors used HRMAS and liquid-state NMR techniques to analyze the whole poplar tissues and their ethanol/water extracts, respectively. The combination of phase- and length-modulated pulses specific of the selected NMR pulse sequences enables a controlled manipulation of nuclear spins that ultimately provides structural and dynamical information and reveals through-bonding or through-space correlations among nuclei, in either mono- or multidimensional systems [3].
