Among the environmentally sensitive sources of genome plasticity, the book treats tandem repeats, mutagenic break repair, transcription-associated mutagenesis and transposable elements. Additionally, it deals with epigenetic mechanisms such as DNA methylation and regulatory RNA-based systems. These not only regulate the activity of mobile DNA, they can also synergize with it. In closing, symbiosis and genetic noise are also discussed as possible sources of phenotypic plasticity.
Brave Genomes emphasizes the role of the environment in generating genotypic and phenotypic diversity. This emerges, in turn, as the most efficient response to challenging conditions.

Authors
Silvia Bulgheresi Associate Professor in Environmental Cell Biology, Department of Functional and Evolutionary Ecology, University of Vienna, Australia.Silvia Bulgheresi is Associate Professor in Environmental Cell Biology and independent researcher at the University of Vienna. Her research on the molecular mechanisms underlying symbiont growth, division and chromosome segregation challenged long-established bacterial cell biology tenets. Since 2008, she has been teaching environmental cell biology, microbial symbioses, as well as microbial genome plasticity to Bachelor, Master ad PhD students. It is in the effort of collecting the notes, thoughts and students' questions that arose over two decades that this book was born.
