20.500.12556/RUL-136786 Silicon mitigates negative impacts of drought and UV-B radiation in plants Due to climate change, plants are being more adversely affected by heatwaves, floods, droughts, and increased temperatures and UV radiation. This review focuses on enhanced UV-B radiation and drought, and mitigation of their adverse effects through silicon addition. Studies on UV-B stress and addition of silicon or silicon nanoparticles have been reported for crop plants including rice, wheat, and soybean. These have shown that addition of silicon to plants under UV-B radiation stress increases the contents of chlorophyll, soluble sugars, anthocyanins, flavonoids, and UV-absorbing and antioxidant compounds. Silicon also affects photosynthesis rate, proline content, metal toxicity, and lipid peroxidation. Drought is a stress factor that affects normal plant growth and development. It has been frequently reported that silicon can reduce stress caused by different abiotic factors, including drought. For example, under drought stress, silicon increases ascorbate peroxidase activity, total soluble sugars content, relative water content, and photosynthetic rate. Silicon also decreases peroxidase, catalase, and superoxide dismutase activities, and malondialdehyde content. The effects of silicon on drought and concurrently UV-B stressed plants has not yet been studied in detail, but initial studies show some stress mitigation by silicon. abiotic stress crop plants antioxidants Si fertilization oxidative stress abiotski stres poljščine antioksidanti gnojenje s Si oksidativni stres true false true Angleški jezik Slovenski jezik Članek v reviji 2022-05-20 13:22:24 2022-05-20 13:22:25 2022-09-15 04:14:20 0000-00-00 00:00:00 2022 0 0 16 str. iss. 1, art. 91 Vol. 11 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 581.1 2223-7747 10.3390/plants11010091 91934979 plants-11-00091-v2.pdf plants-11-00091-v2.pdf 1 1BEA9260F6F51BE88104F9B2B29E19BD 85e6c99fa51775b35a3a23be19fe1ecea244b1e0e4066cc48d9867bf66cd7c70 33e0316a-d82f-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=156575 https://www.mdpi.com/2223-7747/11/1/91 1 01374605-d82f-11ec-8aca-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=156574 Biotehniška fakulteta 0 0 0
