Morphological and biochemical behavior of fenugreek (Trigonella foenum-graecum) under copper stress

Effect of Heavy Metals on Seed Germination of Trigonella foenum-graceum L

“…These results agreed with findings on the Cluster Bean (21); wheat (22); the Psyllium (23); and on Mung bean (24). Heavy metal accumulation was markedly higher in roots as compared to shoots, while both showed a gradual decrease in growth, the effect was more pronounced in roots (25). Effect of Heavy Metals on fresh weight of Trigonella foenum-graceum L.…”

Luteolin Protects HUVECs from TNF-α-induced Oxidative Stress and Inflammation via its Effects on the Nox4/ROS-NF-κB and MAPK Pathways

“…The current study showed that luteolin is able to partly reverse the effects of TNF-α on the level of GSH and activity of SOD in HUVECs. These enzymes are involved in ROS scavenging 29) and associated with the important transcription factor Nrf-2, which binds to the antioxidant response element in the promoter region of many genes 26) ; therefore, this may be another mechanism underlying the decrease in intracellular ROS production mediated by luteolin.…”

Copper-induced changes in nutrient uptake, enzymatic and non-enzymatic antioxidant systems in horehound ( Marrubium vulgare L.)

“…Our findings suggest that phenols are involved in Cu detoxification process, having an increase of phenol and flavonoid contents, as already observed in fenugreek (Elleuch et al 2013). From a physiological point of view, an increase in total phenol and flavonoid content is expected due to their ROS scavenging activity, Cu chelating and detoxifying properties (Gordon & RoedigPenman 1998).…”

“…Accordingly, we studied the effect of Cu-induced stress on SOD, CAT and APX enzymatic activity Marrubium vulgare leaves extracts. Results clearly evidenced that metal stress is able to induce activation of antioxidant enzymes such as SOD, which converts superoxide (O 2 • -) into H 2 O 2 (Dey et al 2015), and CAT, responsible for transformation of H 2 O 2 in water (H 2 O) and oxygen (O 2 ) (Karuppanapandian et al 2011), indicating that these enzymes are involved in the detoxification mechanism in M. vulgare, as already observed in other species (Haribabu & Sudha 2011, Thounaojam et al 2012, Elleuch et al 2013.These results led to hypothesize that such increment is an adaptive response of plants to cope with Cu-induced oxidative stress. To sum up, our observations are in line with literature data (Elleuch et al 2013) and suggest that the generation of reactive oxygen species (ROS) under Cu stress and the SOD and CAT activated are an adaptive mechanism to M. vulgare that serves to maintain the ROS at a steady-state level.…”

“…In contrast, in Cu-tolerant species like Populus deltoides, Haumaniastrum katangense, fenugreek and mustard rapeseed (Guerra et al 2009, Peng et al 2012, Elleuch et al 2013, Feigl et al 2013 Cu was preferentially accumulated in roots.…”
