Nitric oxide mediates γ-aminobutyric acid signaling to regulate phenolic compounds biosynthesis in soybean sprouts under NaCl stress

Enhanced total flavonoid accumulation and alleviated growth inhibition of germinating soybeans by GABA under UV-B stress

“… 24 Previously, research revealed that GABA is a key signaling molecule in the metabolism of phenolic buildup in sprouting soybean seedlings 22 and sprouting barley 25 under salt stress. GABA mediated the accumulation of phenolic compounds and strengthened the antioxidant system in sprouting barley under salt stress according to Ma et al , 25 and similar conclusions were obtained by Xie et al 26 Although GABA has been proven to be a signaling molecule for phenolic component enrichment in growing soybeans when exposed to salt, it is unknown if GABA has the same impact when exposed to UV-B radiation. It is therefore necessary to explore whether GABA can act as a signaling molecule for isoflavone enrichment in germinating soybean under UV-B radiation and its exact mechanism of action.…”

Effect of Amino Acids on Folates Accumulation in Wheat Seedlings during Germination under Red Light Radiation

“…Glutamic acid (Glu) and p ABA are precursors in folate biosynthesis, and the addition of these molecules has been shown to enhance folate synthesis in plants [ 11 ]. Gamma-aminobutyric acid (GABA) is a non-protein amino acid which plays a versatile role in plants and can mediate the synthesis of many bioactive compounds, such as phenolics, as a signal molecule [ 12 ]. Aromatic amino acids, such as tyrosine (Tyr), phenylalanine (Phe), and tryptophan (Try), are potential molecules for enhancing folate accumulation because they are synthesized by chorismite, which is a precursor in p ABA biosynthesis, through the shikimate pathway [ 13 ].…”

Influence of sprouted oat flour substitution on the texture and in vitro starch digestibility of wheat bread

“…OBG was quantified using a 1.3:1.4 mixed-linkage Megazyme β-glucan kit under the manufacturer's instructions (Bray, Wicklow, Ireland). γ-aminobutyric acid (GABA) was determined by HPLC (Agilent, California, China) coupled with a diode array detector based on previously validated methods ( Xie, Wang, Sun, Gu, & Yang, 2021 ). Total phenolic compounds were identified by the Folin–Ciocalteau reagent with modifications.…”
