DNA damage response (DDR) is a term that includes a variety of highly sophisticated mechanisms that cells have evolved in safeguarding the genome from the deleterious consequences of DNA damage. It is estimated that every single cell receives tens of thousands of DNA lesions per day. Failure of DDR to properly respond to DNA damage leads to stem cell dysfunction, accelerated ageing, various degenerative diseases or cancer. The sole function of DDR is to recognize diverse DNA lesions, signal their presence, activate cell cycle arrest and finally recruit specific DNA repair proteins to fix the DNA damage and thus prevent genomic instability. DDR is composed of hundreds of spatiotemporally regulated and interconnected proteins, which are able to promptly respond to various DNA lesions. So it is not surprising that mutations in genes encoding various DDR proteins cause embryonic lethality, malignancies, neurodegenerative diseases and premature ageing. The importance of DDR for cell survival and genome stability is unquestionable, but how the sophisticated network of hundreds of different DDR proteins is spatiotemporally coordinated is far from being understood. In the last ten years ubiquitin (ubiquitination) and the ubiquitin-relative SUMO (sumoylation) have emerged as essential posttranslational modifications that regulate DDR. Beside a plethora of ubiqutin and sumo E1-activating enzymes, E2-conjugating enzymes, E3-ligases and ubiquitin/sumo proteases involved in ubiquitination and sumoylation, the complexity of ubiqutin and sumo systems is additionally increased by the fact that both ubiquitin and sumo can form a variety of different chains on substrates which govern the substrate fate, such as its interaction with other proteins, changing its enzymatic activity or promoting substrate degradation. The importance of ubiquitin/SUMO systems in the orchestration of DDR is best illustrated in patients with mutations in E3-ubiquitin ligases BRCA1 or RNF168. BRCA1 is essential for proper function of DDR and its mutations lead to triple-negative breast and ovarian cancers. RNF168 is an E3 ubiquitin ligase, which creates the ubiquitin docking platform for recruitment of different DNA damage signalling and repair proteins at sites of DNA lesion, and its mutations cause RIDDLE syndrome characterized by radiosensitivity, immunodeficiency and learning disability. In addition, recently discovered the ubiquitin receptor protein SPRTN is part of the DNA replication machinery and its mutations cause early-onset hepatocellular carcinoma and premature ageing in humans. Despite more than 700 different enzymes directly involved in ubiquitination and sumoylation processes only few of them are known to play a role in DDR. Therefore, we feel that the role of ubiquitin and the ubiquitin-related SUMO in DDR is far from being understood, and that this is the emerging field that will hugely expand in the next decade due to the rapid development of a new generation of technologies, which will allow us a more robust and precise analyses of human genome, transcriptome and proteome. In this Research Topic we provide a comprehensive overview of our current understanding of ubiquitin and SUMO pathways in all aspects of DDR, from DNA replication to different DNA repair pathways, and demonstrate how alterations in these pathways cause genomic instability that is linked to degenerative diseases, cancer and pathological ageing.

The free-radical chemistry of DNA had been discussed in some detail in 1987 in my book The Chemical Basis of Radiation Biology. Obviously, the more recent developments and the concomitant higher level of understanding of mechanistic details are missing. Moreover, in the living cell, free-radical DNA damage is not only induced by ionizing radiation, but free-radical-induced DNA damage is a much more general phenomenon. It was, therefore, felt that it is now timely to review our present knowledge of free-radical-induced DNA damage induced by all conceivable free-radical-generating sources. Originally, it had been thought to include also a very important aspect, the repair of DNA damage by the cell’s various repair enzymes. Kevin Prise (Cancer Campaign, Gray Laboratory, L- don) was so kind to agree to write this part. However, an adequate description of this strongly expanding area would have exceeded the allocated space by much, and this section had to be omitted. The directors of the Max-Planck-Institut für Strahlenchemie (now MPI für Bioanorganische Chemie), Karl Wieghardt and Wolfgang Lubitz, kindly allowed me to continue to use its facilities after my retirement in 2001. Notably, our - brarian, Mrs. Jutta Theurich, and her right-hand help, Mrs. Rosemarie Schr- er, were most helpful in getting hold of the literature. I thank them very much. Without their constant help, this would have been very difficult indeed.

Plants are vulnerable to pathogens including fungi, bacteria, and viruses, which cause critical problems and deficits. Crop protection by plant breeding delivers a promising solution with no obvious effect on human health or the local ecosystem. Crop improvement has been the most powerful approach for producing unique crop cultivars since domestication occurred, making possible the main innovations in feeding the globe and community development. Genome editing is one of the genetic devices that can be implemented, and disease resistance is frequently cited as the most encouraging application of CRISPR/Cas9 technology in agriculture. Nanobiotechnology has harnessed the power of genome editing to develop agricultural crops. Nanosized DNA or RNA nanotechnology approaches could contribute to raising the stability and performance of CRISPR guide RNAs. This book brings together the latest research in these areas. CRISPR and RNAi Systems: Nanobiotechnology Approaches to Plant Breeding and Protection presents a complete understanding of the RNAi and CRISPR/Cas9 techniques for controlling mycotoxins, fighting plant nematodes, and detecting plant pathogens. CRISPR/Cas genome editing enables efficient targeted modification in most crops, thus promising to accelerate crop improvement. CRISPR/Cas9 can be used for management of plant insects, and various plant pathogens. The book is an important reference source for both plant scientists and environmental scientists who want to understand how nano biotechnologically based approaches are being used to create more efficient plant protection and plant breeding systems. Shows how nanotechnology is being used as the basis for new solutions for more efficient plant breeding and plant protection Outlines the major techniques and applications of both CRISPR and RNAi technologies Assesses the major challenges of escalating these technologies on a mass scale

Advanced Chemical Biology The modern approach to teaching chemical biology Advanced Chemical Biology is organized around the central dogma of life, progressing from genes to proteins and higher-order cellular structures, including core application areas such as imaging, chemical genetics, activity-based protein profiling, and natural product discovery and biosynthesis. Advanced topics and applications in, e. g., microbiology, developmental biology, and neurobiology, are covered in separate sections. Every chapter is homogeneous in style and layout, consisting of a short historical introduction followed by a description of the underlying concepts and a selection of recent examples of how the concept has been turned into practice. The subdivision of the contents into core and supplemental chapters enables a flexible use in teaching, both for a one-semester and a two-semester course. Written by authors and editors coming from the leading scientific institutions that have developed the concepts and technologies for this discipline, Advanced Chemical Biology includes specific information on topics like: DNA function, synthesis and engineering, chemical approaches to genome integrity, and RNA function, synthesis, and probing Chemical approaches to transcription and RNA regulation in vivo, chemical biology of genome engineering, and peptide/protein synthesis and engineering Directed evolution for chemical biology, chemical biology of cellular metabolism, chemical biology of lipids, and protein post-translational modifications Chemical glycobiology, chemical and enzymatic modification of proteins, genetic code expansion, bio-orthogonal chemistry, and cellular imaging With its broad scope and focus on turning concepts into applications, Advanced Chemical Biology is an excellent starting point for anyone entering the field and looking for a guide to the wide range of available methods and strategies that chemical biology has to offer. With a Foreword by Nobel Laureate Carolyn Bertozzi.
