Metabolite profiling of leaves of three <i>Epilobium</i> species

BACKGROUND: The ability of plants to adapt oxygen deficiency is associated with the presence various adaptations, many which are mediated by significant changes metabolism. These allow resistant wetland grow even in oxygen-deficient environment.
 AIM: aim study was carry out metabolic profiling leaves species Epilobium palustre and hirsutum, mesophyte angustifolium order identify most characteristic metabolome traits hypoxia-resistant plants.
 MATERIALS AND METHODS: Metabolite performed GC-MS. Statistical analysis metabolomics data processed using R 4.2.1 Funny-Looking Kid.
 RESULTS: resulting profile included about 360 compounds. 70 these were identified 50 compounds determined a class. Sugars (64) widely represented obtained profiles. 16 amino 20 carboxylic acids, lipids secondary have been identified. Significant differences revealed between profiles leaf metabolomes E. hydrophytes hirsutum palustre. characterized high levels sugars. practically did not differ from each other accumulation including GABA shunt intermediates, dicarboxylic acids Krebs cycle, metabolites glycolysis lactic acid fermentation, reflects stimulation anaerobic respiration, nitrogen metabolism, alternative pathways NAD(P)H reoxidation CONCLUSIONS: Traits detected hydrophyte can be used assess degree plant resistance deficiency.
