Abstract

Graphical abstract: Highlights: We examined content of flavonoids and amines during de-etiolation of buckwheat seedlings. We explored the impact of methyl jasmonate on the biosynthesis of flavonoids and amines. Atmospheric methyl jasmonate greatly increases PEA level in buckwheat tissues. Abstract: The effects of atmospheric methyl jasmonate on the level of flavonoids and biogenic amines in de-etiolated seedlings of common buckwheat ( Fagopyrum esculentum Moench) were investigated. In cotyledons and hypocotyls of etiolated seedlings, some traces of anthocyanins were found, with no flavones and flavonols identified. A measurable content of flavones and flavonols was, however, determined in roots. De-etiolation process stimulated the accumulation of all flavonoid types. Methyl jasmonate clearly decreased the content of anthocyanins in the hypocotyl, not affecting their level in cotyledons. In case of roots, the content of anthocyanins increased after a 4-day treatment. In general, reduction in the level of flavones and flavonols was recorded only in the hypocotyl, however it was not always significant. Cotyledons of the seedlings treated with methyl jasmonate responded by a slight increase in flavonoids level. Methyl jasmonate considerably induced the accumulation of 2-phenylethylamine in all the seedling organs, increasing the content of putrescine and tryptamine in cotyledons, and decreasing the level of tryptamine in roots.
