“…Flavonoid biosynthesis is known to involve a variety of enzymes. 18 Phenylalanine ammonia-lyase (PAL, EC 4.3.1.5) is the key enzyme of the general phenylpropanoid pathway, which channels L-Phe from the primary metabolic pool to the synthesis of trans-cinnamic acid (t-CA). 19 The t-CA produced is then further transformed into many polyphenol compounds.…”

Present results showed that polyphenol compounds mainly accumulated in cotyledons and hypocotyls. There was a negative correlation between polyphenol compounds and PAL gene expression. The discrepancy suggested that polyphenol compounds might experience transportation within buckwheat sprouts. The study could provide useful information for further application of buckwheat in functional foods, and revelation of the correlation between bioactive components and related gene expressions. © 2018 Society of Chemical Industry.

“…Tartary buckwheat [Fagopyrum tataricum (L.) Gaertn., 2n = 2x = 16], a dicotyledon belonging to the genus Fagopyrum, is an important traditional short-season pseudocereal crop ( Jiang et al, 2007;Zhou et al, 2015;Yao et al, 2017aYao et al, , 2017b. It originated in southwest China, is currently being grown on marginal lands in mountainous areas of western China and the Himalayas, and is highly tolerant to harsh climates (Wang and Campbell, 2007;Zhou et al, 2015;Zhang et al, 2017).…”

Plant‐specific NAC (NAM, ATAF1/2, and CUC2) transcription factors (TFs) play important roles in various stress responses. However, the characteristics and functions of NAC TFs in Tartary buckwheat [Fagopyrum tataricum (L.) Gaertn.], an important pseudocereal crop that is strongly adapted to growth in adverse environments, have not been investigated. Here, eight NAC‐like genes, termed FtNAC2 through FtNAC9, were isolated and characterized from Tartary buckwheat. Amino acid sequence alignment analysis demonstrated that all the FtNAC proteins contain typical NAM domain of the NAC TFs family in the N terminus. Phylogenetic analysis showed that the eight FtNAC TFs were assigned to three abiotic stress‐related functional subgroups. To investigate their roles in response to stresses, the relative expression levels of FtNAC genes were analyzed under abiotic stresses (salt, drought, cold, and ultraviolet B) and exogenous phytohormones (abscisic acid, methyl jasmonate, and salicylic acid) treatments. All the FtNAC genes responded to one or more treatments, among which FtNAC4 and FtNAC7 showed >20‐fold upregulation of messenger RNA levels in response to salt, drought, abscisic acid, and salicylic acid treatments. The expression analysis of the NAC gene family in Tartary buckwheat under abiotic stress open the way to further investigate the molecular mechanism of NAC‐dependent transcriptional control of stress response.

Buckwheat (Fagopyrum esculentum) is a kind of medicinal and edible crops with high Flavonoid content. Flavonoids from tartary buckwheat have significant therapeutic effects on vascular diseases, diabetes and obesity. In this paper, the extracting technologies of flavonoids from buckwheat were investigated. The results showed that the optimum parameters for the extraction is temperature 60℃, alcohol concentration 60%, solid to liquid ratio 1:20, pH=2, duration 120 min.
