Possible Interaction: Antioxidants and Silicon

“In addition, Si relieved root damage, promoted the increase of photosynthetic efficiency, and improved the antioxidant system to resist SMZ toxicity.”

“Moreover, Si also activates antioxidant system which helps in scavenging of free radicals generated under Meth herbicide stress in wheat seedlings.”

“Here, we discuss recent findings on how silicon is able to modulate antioxidant defense of plants in response to oxidative stress triggered by different abiotic constraints.”

“Moreover, Si influences the oxidative status of plants by modifying the activity of various antioxidants , improves membrane stability, and acts upon the gene expression, although its exact role in these processes is still not well explained.”

“The inoculated plants treated with Si exhibited higher level of auxins and improved activity of antioxidant enzymes under Pb stress.”

“Furthermore, Si alleviated oxidative damages under both NaCl and PEG by regulating antioxidant enzyme activities.”

“ Silicon stimulated growth, proline content … activities of various antioxidant biomolecules and enzymes, leaf Ca2+, K+ and N, endogenous H2S and L-DES activity, but reduced H2O2 and MDA contents, membrane leakage and leaf B. Silicon-induced B tolerance was further enhanced by 0.2 mM NaHS, a H2S donor.”

“4) Silicon application direct/indirectly mitigates oxidative stress via regulating the antioxidant defense and polyamine metabolism. (”

“ Silicon up-regulated most of the antioxidant defense components as well as glyoxalase systems, which helped to improve ROS scavenging and MG detoxification.”

“Application of silicon , along with NaCl, in the test seedlings of both the cultivars, reduced ROS accumulation and boosted antioxidant defense mechanism, through enhancing ascorbate and GSH levels, and activities of ascorbate-glutathione cycle enzymes as well.”
