Abstract
Za obranu od stresa uzrokovanog teškim metalima biljke su razvile različite antioksidacijske i detoksikacijske mehanizme u kojima glioksalazni sustav ima važnu ulogu. Budući da je soja značajna poljoprivredna kultura vrlo je važno poznavati detoksikacijske mehanizme koji mogu doprinijeti zaštiti od teških metala kao što je kadmij, čija sve veća prisutnost u okolišu ugrožava razvoj i prinos biljaka. Cilj ovoga istraživanja bio je odrediti učinak različitih koncentracija kadmija na glioksalazni sustav, odnosno aktivnost enzima glioksalaza 1 (GLO1), u korijenu i izdanku tri kultivara soje koji se međusobno razlikuju u stupnju akumulacije kadmija u zrnu. Utjecaj kadmija na aktivnosti enzima glioksalaznog sustava ovisio je o primjenjenoj koncentraciji kadmija i tipu tkiva, ali ne i o kultivaru. Aktivnost enzima GLO1 u izdanku sva tri kultivara soje povećana je pri svim primijenjenim količinama kadmija, dok u korijenu soje postoji trend povećanja koji nije značajan kod svih koncentracija, ali je u korelaciji s količinom primijenjenog kadmija. Uvid u biokemijske mehanizme detoksikacije u kojima važnu ulogu ima i glioksalazni sustav omogućava razvijanje strategija za povećanje tolerancije na kadmij
Abstract (english)
To protect from stress caused by heavy metals, plants have evolved different antioxidative and detoxification mechanism in which glyoxalase system has an important role. Because soybean crops are agriculturally very important, it is also important to know detoxification mechanisms that may contribute to the protection against heavy metals such as cadmium, which presence in the environment threatens the development and yield of plants. The aim of this study was to determine the effect of different concentrations of cadmium on glyoxalase system and activity of enzyme glyoxalase І (GLO1) in roots and shoots of three soybean cultivars, which differ from each other in degree of Cd accumulation in the grain. The influence of cadmium on the enzymes activity depends on applied concentration of cadmium and on the type of tissue, but not on cultivar. The activities of enzyme GLO1 in shoots of all three varieties of soybean were increased with all applied concentration of cadmium, while in soybean roots the activity has a tendency to increase, althought not significant at lower concentrations, but there is a correlation between applied concentration of cadmium and the activity of enzyme GLO1. Understanding biochemical mechanisms of detoxification, in which glyoxalase system has an important role, enables the development of strategies for increasing tolerance to Cd
