ACCUMULATION OF CR6+, PB2+ AND CD2+ AND ULTRAVIOLET RADIATION ALTER METHYLATION AND GENOMIC DNA STATUS IN RAMALINA FARINACEAE

In this study was aimed to determine the genotoxic effect of Ramalina farinacea lichen species against stress sources at molecular level. After applying three different heavy metals (Pb2+, Cd2+, and Cr6+) R. farinacea, extent which sample absorbed these determined by Flame Atomic Absorption Spectroscopy. RAPD MSAP-AFLP assays were also used status DNA damage. The metal analysis showed that had high levels Pb2+, Cr6+ content. According results obtained from analyses, band changes observed seven primers stresses UV stress. An increase in Genomic Template Stability (GTS) during time treated with all concentrations. radiations revealed highest polymorphism lowest GTS rate depending on dose. Among methylation combinations, Type II found show altered response contents radiations. can be level as a biomarker suitable effect. This is first reveal damage using species.
