Understanding of how species may evolve in response to environmental changes remains relatively unclear, particularly for plants. Plants, because of their intrinsic immobility, are constantly exposed to various environmental agents and endogenous processes that impose damage to DNA and cause genotoxic stress, which can reduce plant genome stability, growth and productivity. Like any other organisms plants employ a wide variety of strategies to either reverse, excise, or tolerate the presence of DNA damage products. Although repair and damage tolerance mechanisms have been thoroughly described in E. coli, Saccharomyces cerevisiae, rodents and human, surprisingly little is known about these processes in plants. However, in recent years, there has been increased interest in plant DRR and in using plants as models for understanding the under lying mechanism of DRR [4]."}
