Metabolic profiling of Pratylenchus thornei resistant and susceptible wheat genotypes indicates that fatty acid, glycerolipid and flavonoid classes of metabolites constitutively expressed in resistant wheat roots could reduce nematode reproduction The root-lesion nematode Pratylenchus thornei reduces wheat production in many parts of the world. In this study the metabolic profiles of two wheat genotypes QT16258 (moderately resistant) and ′Janz′ (susceptible) were compared at 8 wk post inoculation with or without P. thornei. We performed untargeted liquid chromatog. mass spectrometry anal. (LC-MS) of the wheat root samples. A total of 11,704 MS features were identified, out of which 765 MS features were annotated using inhouse chem. standards Principal components anal. (PCA) and partial least square discriminant anal. (PLS-DA) indicated dissimilarity of the metabolome between P. thornei resistant and susceptible genotypes. Two-way anal. of variance indicated that metabolic differences were mainly constitutive rather than induced by inoculation with P. thornei. Eighty-four annotated metabolites were significantly (p ≤ 0.01) higher in relative concentration in QT16258 than Janz and belonged to the following classes of metabolites: flavonoids, fatty acids, glycerolipids, alkaloids, tannins, nucleotides, steroid glycosides and terpenoids. Eighty-five annotated metabolites were significantly (p ≤ 0.01) higher in relative concentration in Janz than QT16258 and belonged to the following classes of metabolites: amino acids, sugars, flavonoids and alkaloids. Several metabolites at higher concentration in QT16258, including quercetin-3,4-O-di-beta-glucoside (flavonoid), linoleic acid (fatty acid), lysophosphatidylethanolamine (glycerolipid), hirsutine (alkaloid), 1-methylsulfinylbutenyl-isothiocyanate (glucosinolate), could potentially strengthen the root cell walls to inhibit nematode penetration and/or reduce nematode motility. Some metabolites at higher concentrations in susceptible Janz, including phenolics, coniferyl alc. and indole acetic acid conjugates, could be nematode attractants as well as part of a hypersensitive browning reaction to nematode invasion. This study involved multiple reactions and reactants, such as (2S,3R,4S,5S,6R)-2-(3-Hydroxy-5-((E)-4-hydroxystyryl)phenoxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol (cas: 27208-80-6Safety of (2S,3R,4S,5S,6R)-2-(3-Hydroxy-5-((E)-4-hydroxystyryl)phenoxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol).

The most acidic simple alcohols (methanol and ethanol) are about as acidic as water, and most other alcohols are somewhat less acidic. Grignard and organolithium reagents are powerful tools for organic synthesis, and the most common products of their reactions are alcohols.Safety of (2S,3R,4S,5S,6R)-2-(3-Hydroxy-5-((E)-4-hydroxystyryl)phenoxy)-6-(hydroxymethyl)tetrahydro-2H-pyran-3,4,5-triol
