“…In this study, the total phenolic contents in spicas of P. vulgaris under UV-B radiation were slightly higher than those of control treatment. Similar results were obtained by Manaf et al (2016) and Inostroza-Blancheteau et al (2014). Many studies have shown that phenolic compounds absorb in the UV-B electromagnetic region (280-320 nm) that and these compounds function as ROS scavengers to protect plants against UV-B radiation (Tegelberg et al 2001;Ortuñoa et al 2006).…”

Prunella vulgaris plants (full-bloom stage) were subjected to short-term (15 days) UV-B radiation in a growth chamber. UV-B radiation was effective at enhancing morphological and biomass characteristics and decreasing chlorophyll contents of P. vulgaris. Treatment of P. vulgaris with artificial UV-B radiation significantly increased peroxidase (POD), superoxide dismutase (SOD) and glutathione (GSH) activities compared to the control treatment. UV-B radiation significantly increased the levels of hydrogen peroxide (H 2 O 2 ), malondialdehyde (MDA) and proline in leaves of P. vulgaris compared to those of control plants. In addition, the contents of total flavonoids, rosmarinic acid, caffeic acid and hyperoside significantly increased under UV-B radiation. The total phenolic levels also increased under UV-B treatment. These results demonstrated that short-term UV-B radiation can enhance production of secondary metabolites in P. vulgaris, resulting in increased spica yield compared to that of control plants.

“…Quantitative real‐time PCR (qRT‐PCR) reactions were conducted in order to determine the expression patters of AcUFGT in A. chilensis leaves. All qRT‐PCR reactions were performed using Brilliant II SYBR Green QPCR Master Mix (Agilent Technologies, Santa Clara, CA) in an ABI 7300 Real‐Time PCR system (Applied Biosystems, Foster City, CA) using the procedure described by Inostroza‐Blancheteau et al (). EF1a sequences of Vitis vininfera , Populus euphratica , and Prunus persica were obtained from Genbank ® .…”

Abscisic acid is involved in phenolic compounds biosynthesis, mainly anthocyanins, in leaves of Aristotelia chilensis plants (Mol.) subjected to drought stress

Abscisic acid (ABA) regulates the physiological and biochemical mechanisms required to tolerate drought stress, which is considered as an important abiotic stress. It has been postulated that ABA might be involved in regulation of plant phenolic compounds biosynthesis, especially anthocyanins that accumulate in plants subjected to drought stress; however, the evidence for this postulate remains elusive. Therefore, we studied whether ABA is involved in phenolic compounds accumulation, especially anthocyanin biosynthesis, using drought stressed Aristotelia chilensis plants, an endemic berry in Chile. Our approach was to use fluridone, an ABA biosynthesis inhibitor, and then subsequent ABA applications to young and fully-expanded leaves of drought stressed A. chilensis plants during 24, 48 and 72 h of the experiment. Plants were harvested and leaves were collected separately to determine the biochemical status. We observed that fluridone treatments significantly decreased ABA concentrations and total anthocyanin (TA) concentrations in stressed plants, including both young and fully-expanded leaves. TA concentrations following fluridone treatment were reduced around fivefold, reaching control plant levels. ABA application restored ABA levels as well as TA concentrations in stressed plant at 48 h of the experiment. We also observed that TA concentrations followed the same pattern as ABA concentrations in the ABA treated plants. Quantitative real-time PCR revealed that AcUFGT gene expression decreased in fully-expanded leaves of stressed plants treated with fluridone, while a subsequent ABA application increased AcUFGT expression. Taken together, our results suggest that ABA is involved in the regulation of anthocyanin biosynthesis under drought stress.

“…This enzyme undergoes isomerization through the action of chalcone isomerase to form a flavanone. Also, anthocyanidin flavinium ions are produced by anthocyanidin synthase (ANS) and the glycosylated UDP-GIc: flavonoid-3-O-glycosyltransferases, responsible for the transfer of glucoside to the 3-O position of flavonoids, is a key enzyme in regulating anthocyanin synthesis during red coloration (Inostroza-Blancheteau et al, 2014).…”
