Abstract
Selen (Se) je nutrijent s dvojakom prirodom djelovanja na biljke: pri niskim koncentracijama ponaša se kao antioksidans, pospješuje njihovu prilagodbu i otpornost na abiotički stres, dok pri prekomjernim kocentracijama djeluje kao prooksidans. Glioksalazni sustav jedan je od mehanizama zaduženih za detoksifikaciju reaktivnih kisikovih vrsta i karbonilnih spojeva čiji je nastanak induciran između ostalog i visokim koncentracijama Se. S ciljem istraživanja aktivnosti glioksalaze I (GLO1) u odgovoru na oksidativni stres, sjeme pšenice (Triticum aestivum) tretirano je s pet različitih koncentracija dvaju oblika Se (otopine selenita i selenata). U izdancima pšenice došlo je do porasta aktivnosti enzima GLO1 samo pri najvišim koncentracijama selenita i selenata (50 µM), dok je u korijenu jedino najviša koncentracija selenita izazvala povišenu aktivnost GLO1 enzima. Utjecaj Se na aktivnost GLO1 ovisi o primijenjenoj koncentraciji, kemijskom obliku Se te vrsti biljnog organa koji je tretiran.
Abstract (english)
Selenium (Se) is a nutrient with dual effect on plants: at low concentrations it acts as an antioxidant, enhances their acclimation i resistance to abiotic stress, while at excessive concetrantions it acts as prooxidant. Glyoxalase system is one of the available mechanisms responsible for detoxification of reactive oxygen species and carbonyl compounds whose production canbe induced with high Se concentrations. In order to investigate glyoxalase 1 (GLO1) activity in response to oxidative stress, seeds of wheat (Triticum aestivum) were treated with five different concentrations of two different forms of Se (selenite and selenate). In wheat shoots, the activity of GLO1 enzyme increased only at the highest concentrations of selenite and selenate (50 µM), while in the roots only the highest concentration of selenite caused increased activity of GLO1 enzyme. The effect of Se on GLO1 activity depends on the concentration applied, the chemical form of Se and the type of plant organ being treated.
