The application of high throughput 1H-NMR of unpurified extracts to determine to determine genetic diversity and the contents of polar components in grain of wheat

Methods and results
milled whole wheat grain was extracted with 80:20 D2O:CD3OD containing 0.05% d4– trimethylsilylpropionate (TSP). 1H-NMR spectra were acquired under automation at 300 °K using an Avance Spectrometer operating at 600.0528 MHz. Regions for individual metabolites were identified by comparison to a library of known standards run under identical conditions. The individual 1H-NMR peaks or levels of known metabolites were then compared by Principal Component Analysis using SIMCA-P software.

high throughput 1H-NMR is an excellent tool to compare the extent of genetic diversity within and between wheat species, and to quantify specific components (including glycine betaine, choline and asparagine) in individual genotypes. It can also be used to monitor changes in composition related environmental factors and to support comparisons of the substantial equivalence of transgenic lines.
