Description
The proposed research project is aimed to provide new insights on the spore resistance to heavy ions and the effects on different linear energy transfer (LET)-charged HZE particles. With this project, spores of Bacillus subtilis 168, (wild-type and several selected DNA repairdeficient strains) were used for studying the microbial response heavy ions irradiation. DNA repair capabilities were investigated be the determination of the spore survivability and spore-specific protection mechanisms after irradiation. The activation of DNA repair genes were detected during germination by using DNA microarrays. For studying the DNA repair of treated spores during germination an integrated systems approach was used, id est (i.e.) all experiments were performed in a combination of various biochemical and molecular biological methods to study the spore resistance to heavy ion bombardment.
