SSR markers as tools to reveal mutation events in Scots pine (Pinus sylvestris L.) from Chernobyl

Microsatellites (SSRs) were surveyed to detect somatic mutations caused by chronic irradiation in Pinus sylvestris from Chernobyl (Ukraine). The analysed trees grow close to the exploded nuclear power plant. They survived the accident, but show morphological anomalies and reduced growth and vitality. Ionising radiation is a known mutagen which causes double-strand breaks of DNA in all living organisms. Using six SSR markers, one tree was found in which a mutation (deletion) was detected at the gene locus SPAG 7.14.
