“…In plants, the biosynthesis of phenolic acids is primarily controlled by the phenylpropanoid pathway, with l ‐phenylalanine serving as the primary substrate 47 . Within this pathway, the major rate‐limiting enzymes, PAL, C4H and 4CL, play a pivotal role in regulating the normal operation of the pathway, thereby influencing the phenolic content in plants 48 . In this work, BR treatment significantly increased TPC, the levels of main individual phenolic compounds (including p ‐hydroxybenzoic acid, p ‐coumaric acid, gallic acid, fumalic acid and caffeic acid) and the activities of PAL, C4H and 4CL in mung bean sprouts during storage (Figs 4 and 5).…”

BACKGROUNDThe effects of exogenous brassinolide (BR) treatment (3.0 μM) on phenolic biosynthesis in mung bean sprouts were investigated. This investigation included the analysis of sugar content, substrates within the phenylpropane pathway, energy substances, enzymatic activity within the phenylpropane pathway, sugar metabolism and energy metabolism.RESULTSResults showed that BR treatment significantly increased the levels of total phenolics, p‐hydroxybenzoic acid p‐coumaric acid, gallic acid, fumalic acid, and caffeic acid. This enhancement was accomplished through the elevation of L‐phenylalanine levels and the activation of enzymes associated with the phenylpropane pathway in mung bean sprouts, including phenylalanine ammonia‐lyase, cinnamate 4‐hydroxylase and 4‐coumarate CoA ligase. Furthermore, BR treatment induced alterations in sugar metabolism in mung bean sprouts as evidenced by the increased levels of glucose, fructose, sucrose and phosphoenolpyruvate. Moreover, increased activity was observed for enzymes linked to sucrose metabolism and glycolysis in the BR‐treated group. Concurrently, BR treatment bolstered the levels of adenosine triphosphate and energy charge in mung bean sprouts, which was attributed to the activation of H+‐adenosine triphosphatase, Ca2+‐adenosine triphosphatase and succinic dehydrogenase.CONCLUSIONThese results suggest that BR treatment can accelerate the accumulation of phenolic compounds in mung bean sprouts. This effect is achieved not only through the activation of the phenylpropane pathway, but also through the modulation of sugar and energy metabolism. The modulation provides ample energy and a substrate for the biosynthesis of phenolics.This article is protected by copyright. All rights reserved.

BackgroundPhenolic acid exhibits a variety of well‐known physiological functions. In this study, optimal germination conditions to ensure total phenolic acid enrichment in barley sprouts induced by salicylic acid treatment and its effects on sprout physiology and activity, as well as the gene expression of key enzymes for phenolic acid biosynthesis, were investigated.ResultsWhen sprouts were treated with 1 mM salicylic acid during germination and germinated at 25 °C for 4 days, the phenolic acid content was 1.82 times that of the control, reaching 1221.54 μg/g FW. Salicylic acid significantly increased the activity of phenylalanine aminolase and cinnamic acid‐4‐hydroxylase and the gene expression of phenylalanine aminolase, cinnamic acid‐3‐hydroxylase, cinnamic acid‐4‐hydroxylase, 4‐coumaric acid‐coenzyme A, caffeic acid O‐methyltransferase, and ferulate‐5‐hydroxylase in barley sprouts. However, salicylic acid treatment significantly increased malondialdehyde and H2O2 content, H2O2 and O2− fluorescence intensity, as well as significantly decreased sprout length and fresh weight. Salicylic acid treatment markedly increased the activity of peroxidase and catalase and the gene expression of peroxidase, catalase, and ascorbate peroxidase in barley sprouts.ConclusionSalicylic acid treatment during barley germination significantly promoted the enrichment of total phenolic acid by increasing the activities and gene expression levels of enzymes involved in the phenolic acid biosynthesis pathway. Salicylic acid induced the accumulation of reactive oxygen species, inhibited sprout growth, and activated the antioxidant system. This study provides a basis for the future development of functional foods using phenol acid‐rich plants as raw materials.This article is protected by copyright. All rights reserved.
