Gaba Synthesis

NaCl stress causes oxidative stress in plants; γ-aminobutyric acid (GABA) could alleviate such abiotic stress by enhancing the synthesis of phenolics, but the underlying mechanism is not clear. We investigated the effects of GABA on phenolics accumulation in soybean sprouts under NaCl stress by measuring changes in the content of physiological biochemicals and phenolic substances, in the activity and gene expression of key enzymes, and in antioxidant capacity. GABA reduced the oxidative damage in soybean sprouts caused by NaCl stress and enhanced the content of total phenolics, phenolic acids, and isoflavones by 16.58%, 22.47%, and 3.75%, respectively. It also increased the activities and expression of phenylalanine ammonia lyase, cinnamic acid 4-hydroxylase, and 4-coumarate coenzyme A ligase. Furthermore, GABA increased the activity of antioxidant enzymes and the antioxidant capacity. These events were inhibited by 3-mercaptopropionate (an inhibitor for GABA synthesis), indicating that GABA mediated phenolics accumulation and antioxidant system enhancement in soybean sprouts under NaCl stress.

A rare noriridoid and six known phenolic compounds were isolated from the parasite plant Rhopalocnemis phalloides. Using spectroscopic methods, these compounds were identified as 10-acetoxy- cis-2-oxabicyclo[4.3.0]nonan-7-en-3-one (1), p-hydroxybenzoic acid (2), protocatechuic acid (3), gallic acid (4), coniferyl aldehyde (5), l- O-trans-cinnamoyl-β-D-glucoside (6), and coniferin (7). The noriridoid compound is the first reported from the family Balanophoraceae. Of the isolated compounds, coniferyl aldehyde had the strongest inhibitory effect on nitric oxide production (IC50 = 8.24 μM).
