Abstract / Bemerkung
Only little is known about the effect of a varying sulfur (S) nutrition on the pattern of metabolites in different organs of the ears of winter wheat (Tritcum aestivum L.) at final maturity. More insights into the metabolome as influenced by increasing S-fertilizer rates would, however, be of particular interest in order to unravel S-dependent physiological processes related to grain filling in wheat. We have therefore investigated the effects of varying sulfur nutrition on metabolite composition and distribution in the organs of the wheat ear and vegetative organs at final maturity. Gas chromatography-mass spectrometry-based metabolite profiles revealed that S deficiency decreased the bulk of metabolites in the straw in favor of an increasing metabolite concentration in the husk, rachis, and grains. Surprisingly, only four out of 109 detectable metabolites, namely N-acetyl glucosamine, lysine, ferulic acid, and -aminoisobutyric acid were most responsible for organ-specific differences in the metabolite profiles. Under S-deficient conditions, N-acetyl-glucosamine, lysine, and -aminoisobutyric were increasingly transferred from source tissues into the ears and grains.
