20.500.12556/RUL-179381 Noccaea praecox leaf metabolomes from unpolluted and metal-polluted sites Noccaea praecox is a hyperaccumulating plant, i.e. the Cd, Zn, and Pb concentrations in leaves exceed 100-fold the non-toxic levels. In this study, we report the untargeted leaf metabolome of N. praecox from an unpolluted site (Lokovec) and a metal-polluted site (Žerjav) in Slovenia. Using UPLC-MS/MS and metabolomic analysis, we identified 7,253 metabolites: 6,659 were non-annotated, and 594 were annotated. Among the identified metabolite classes, carbohydrates, terpenoids, flavonoids, and organic acids were the most dominant. Principal Component Analysis revealed distinct metabolomic profiles between the two N. praecox ecotypes, suggesting environmental-related effects in N. praecox physiology. This dataset is a valuable resource for studies on plant adaptation, metal accumulation, and metabolite biosynthesis under metal-stress conditions. hyperaccumulators Noccaea praecox untargeted metabolome metal pollution metabolomics rani mošnjak privzem kovin hiperakumulacijska vrsta netarčni metabolom metabolomika Noccaea praecox onesnaženje s kovinami true false true Angleški jezik Slovenski jezik Članek v reviji 2026-02-12 10:45:11 2026-02-12 10:45:14 2026-02-13 04:27:47 0000-00-00 00:00:00 2025 0 0 Str. 161-165 no. 3 Vol. 68 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 58 1854-3073 10.14720/abs.68.3.21668 253719811 ACTA25_Stevilka_68_3_161-165_clanek11_a4_.pdf ACTA25_Stevilka_68_3_161-165_clanek11_a4_.pdf 1 58ADA00047ECBA123ACCDFEA699AE71E cf827adc698f4e87ee9a77f0ad8bd27154d19de9da0fd8d226af9b7ae0ad8926 70203c8b-07f7-11f1-a1ba-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=227840 https://journals.uni-lj.si/abs/article/view/21668 1 5d99330a-07f7-11f1-a1ba-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=227839 Biotehniška fakulteta Acta biologica slovenica 0 0 0
