Metabolic profile of sweet potato leaves and roots

2019

A preliminary characterization of metabolic profile of sweet potato roots and leaves is important to identify compounds associate with nutritional value. Drapal et al 2019 described a metabolic profile of 27 cultivars of sweet potato including landraces and improved varieties.

A total of 130 metabolites were identified in leaf and storage root tissues harvested from 9-month-old plants grown at greenhouse conditions, four repetitions each. A third of all identified compounds were classified as part of the phenylpropanoid metabolism, while the other metabolites within the following metabolic groups: amino acids, sugars, tri-carboxyl acid cycle, sterols, membrane precursors and isoprenoids (Isopentenyl pyrophosphate-IPP derived). Different quantification methods were used ultra-high-performance liquid chromatography (UPLC), liquid chromatography-mass spectrometry (LC-MS), gas chromatography-mass spectrometry (GC-MS), and near-infrared reflectance spectroscopy (NIRS).

A set of 23 accessions in this study are available for distribution at the International Potato Center Genebank. A selection of 47 metabolites and their concentration (µg/g of dry weigh – DW) in leaves and/or roots is presented in this dataset. Mainly amino acids (Alanine, Arginine, Asparagine, Aspartic acid, γ-Amino butyric acid, Glutamic acid, Glycine, Histidine, Isoleucine, Leucine, Phenylalanine, Proline, Tryptophan, and Tyrosine), cell wall or membrane precursors (α-linolenic acid, Erythronic acid/Threonic acid, Gluconic acid, Linoleic acid, Palmitic acid, and Stearic acid), isoprenoids (Abscisic acid, α-Tocopherol, β-Carotene, γ-Tocopherol, Lutein, and Phytoene), phenolics (Caffeic acid, Cinnamic acid, Kaempferol-3-O-rutinoside, Kaempferol-3-O-rutinoside_1, o-Coumaric acid, Quercetin-glucoside malic acid, and trans-Caffeic acid), sugars (Fructose, Glucose, Glucose/Mannose/Galactose/Sorbose, Inositol, Mannose, and Sucrose), and tri- carboxyl acid cycle compounds (Citric acid, Fumaric acid, Isocitric acid, Maleic acid, and Malic acid).
