“…Multiple studies show that UV-C light exposure induced stilbene biosynthesis in different plant species (e.g., grapevine, pine, peanut, and gnetum), and the induction was accompanied by a transcriptional activation, protein accumulation, and enzyme activation of STS and some other stilbene biosynthesis enzymes (Wang et al 2010Tang et al 2010;Suzuki et al 2015;Deng et al 2016Deng et al , 2017Kiselev et al 2017). For grapevine berries, it has been shown that the induction of resveratrol biosynthesis after UV-C irradiation occurred primarily in the form of t-resveratrol (not piceids) and was dependent on the berry developmental stage .…”

“…Notably, Tang et al (2010) reported that resveratrol production contributed to the tolerance of peanut to UV-C by stimulating ROS accumulation and activation of antioxidant enzymes. Thus, it is also possible that resveratrol and other stilbenes could, in turn, stimulate ROS production and thus accommodate the active stilbene production.…”

Main conclusion This review analyzes the advances in understanding the natural signaling pathways and environmental factors regulating stilbene biosynthesis. We also discuss the studies reporting on stilbene content and repertoire in plants.Stilbenes, including the most-studied stilbene resveratrol, are a family of phenolic plant secondary metabolites that have been the subject of intensive research due to their valuable pharmaceutical effects and contribution to plant disease resistance. Understanding the natural mechanisms regulating stilbene biosynthesis in plants could be useful for both the development of new plant protection strategies and for commercial stilbene production. In this review, we focus on the environmental factors and cell signaling pathways regulating stilbene biosynthesis in plants and make a comparison with the regulation of flavonoid biosynthesis. This review also analyzes the recent data on stilbene biosynthetic genes and summarizes the available studies reporting on both stilbene content and stilbene composition in different plant families.

“…The supernatant (1 mL) was mixed with 1 mL of 0.6% thiobarbituric acid and then heated at 95°C for 30 min. The absorbances were determined at 450, 532 and 600 nm, and the MDA content was estimated by the formula C (lM) = 6.45 (A 532 -A 600 ) -0.56 A 450 (Tang et al 2010). …”

To investigate whether paraquat (PQ) is involved in regulation of antioxidant enzymes and lipid peroxidation under short-term salt stress, and to elucidate the physiological mechanism of salt stress mitigated by PQ, a cucumber cultivar (cv. Chunguang no. 2) was exposed to 100 mM NaCl for 48 h after pre-treatment with 10 lM PQ for 1 h. When compared to the control, salt stress increased the levels of malonaldehyde (MDA), superoxide radical (O 2 Á-) and hydrogen peroxide (H 2 O 2 ) and the activities of antioxidant enzymes, such as superoxide dismutase (EC 1.15.1.1), ascorbate peroxidase (EC 1.11.1.11) and glutathione reductase (EC 1.6.4.2) in the cucumber leaves. Under salt conditions, PQ pre-treatment prevented oxidative stress as observed by the decreases in MDA, H 2 O 2 and O 2 Á-that correlated with the increase in antioxidant defenses. We propose that, at low concentrations, the PQ pre-treatment can reduce the salt-induced oxidative damage by increasing the antioxidative mechanisms in cucumber plants.

“…Balakumar et al (1997) reported increased catalase activity in tomato plants after UV-B irradiation. Increased peroxidase activity under the influence of UV-B irradiation has been reported frequently in, for example, barley (Mazza et al, 1999), sugar beet (Panagopoulas et al, 1990), sunflower cotyledons (Yanarelli at al., 2006b), long green cucumber cultivar (Kataria et al, 2007), wheat and mung bean (Agrawal and Ratore, 2007), spinach (Lei at al., 2008), Picea asperata seedlings (Han et al, 2009) and peanut (Tang et al, 2010). Sometimes, however, the activity of this enzyme is found to decline when the irradiation dose is too high (Rao et al, 1996).…”

Ultraviolet-B (UV-B) radiation negatively affects plant cells, causing reactive oxygen species (ROS) to be generated. To study the effects of increased UV-B exposure on antioxidant processes, we exposed germination-stage cucumber seedlings to increased ultraviolet radiation and analyzed hydrogen peroxide content and the activity of superoxide dismutase (SOD), catalase (CAT), guaiacol peroxidase (GPX) and syringaldazine peroxidase (SPX). Enzymatic antioxidant system activity generally increased after UV-B supplementation. Activation of CAT, GPX and SPX in cucumber cotyledons correlated positively with increases in SOD activity and hydrogen peroxide content. The results indicate that ROS accumulated despite higher engagement of the enzymatic antioxidant system, and that elevated UV-B radiation triggered oxidative stress in the cucumber cotyledons.K Ke ey y w wo or rd ds s: : Catalase, guaiacol peroxidase, H 2 O 2 , superoxide dismutase, syringaldazine peroxidase.
