The Assessment of Metal Resistance through the Expression of Hsp-70 and HO-1 Proteins in Giant Reed

None of our investigations have identified stress in response to the HSP70 and HO-1 proteins metals under study, which aimed understand genetic basis metal tolerance Arundo donax. Thus, present work investigate levels expression two important stress-related proteins, HSP70, A. donax after exposure various metals. The plants were collected from uncontaminated sites Abbottabad, Pakistan. Their rhizomes grown Hoagland solution, upon attaining suitable biomass, used effects on protein expression. treatments carried out with synthetic wastewater containing four Cr (0, 34, 66, 134, 267 mgL−1), namely, Cd, As, Pb, Cu Ni 25, 50, 75, 100 for three weeks. applied according a randomized block design (RBD) based hydroponics. selected was examined 10 days exposure. For studies, leaves separated following previously reported standard procedure. maximum level expressions noted at 66 mgL−1 Cr, then it slightly declined. Significantly, high observed Cd concentrations 50 mgL−1. Cu, As Ni, significantly 75 these showed linear increase increasing giant reed. It is clear research that may contribute plant stress, addition other possible mechanisms.
