Book excerpt: The techniques used to decipher the genetic makeup of species as well as epigenetic mechanisms are essential for explaining life forms and studying their DNA. As a eukaryotic model, Paramecium is well suited for genetic analysis. Taking a rather unconventional view of genetics, Paramecium: Genetics and Epigenetics explores how to use this protozoan as a basis for studying complex cells. The book discusses various aspects of Paramecium, including the cortex, the cytoplasm, nuclei, asexual fission, conjugation, autogamy,macronuclear regeneration, cytogamy, life cycle phases, and behavior. It examines the assorted mating types of the genus and how these mating types are determined. It also elucidates some techniques that identify genetically defined genes with the DNA from a library that comprises those genes and details the genetic, epigenetic, chemical, and molecular facets of several different traits. In addition, the authors chronicle the history and reemergence of investigating RNA and DNA in Paramecium. With many powerful tools now available, Paramecium research is entering a new frontier in molecular biology. A full account of Paramecium genetics, this book presents a wealth of time-consuming observations and remarkable phenomena that will lead to a better understanding of complex cells.

This book was released on 2013 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents a study of the molecular mechanisms underlying the determination of mating types in the ciliate Paramecium tetraurelia, and their non-Mendelian inheritance. The identification of mutations known to affect mating types reveals that type E depends on expression of the transmembrane protein mtA, which in turn requires the transcription factors mtB and mtC. Type O is determined by excision of the mtA promoter during the development of the somatic macronucleus from the germline micronucleus, a stage when the genome is entirely rearranged to eliminate transposable elements and their single-copy remnants. These deletions are targeted by scnRNAs, germline-derived small RNAs produced during meiosis that first scan the maternal macronuclear genome to identify missing sequences, and then allow the zygotic macronucleus to reproduce the same deletions. Excision of the mtA promoter is regulated by the scnRNA pathway, explaining the maternal inheritance of mating types. In the sibling species P. septaurelia, mating-type genes are conserved but type O is determined by coding-sequence deletions in mtB. Three main conclusions are drawn from this study: (1) independent evolution of similar mechanisms in the two species suggests frequent exaptation of the scnRNA pathway to regulate cellular genes and to mediate epigenetic inheritance of phenotypic polymorphisms; (2) the mtF gene, required for type O determination, encodes a novel trans-acting factor involved in a subset of rearrangements; (3) an insertion polymorphism in the germline mtB gene reveals an unanticipated consequence of scnRNA-mediated deletions, potentially resulting in hybrid dysgenesis and speciation.

Available in PDF, EPUB and Kindle. Book excerpt: Why a Book on Paramecium? Biologists usually concentrate their efforts on a single problem and a single organism. There is a difficulty with this practice, however, for as work on a problem proceeds it often becomes more ad vantageous to study the problem in another organism. Some biologists avoid the difficulty by moving from one organism to the other as the problem de mands. However, this tactic also has a disadvantage, for a thorough knowledge of the life cycle and thorough mastery of ways to handle a given organism in the laboratory are obviously of great importance to the researcher, and one can never know several organisms as well as one can know a single one. Another way of doing research is to pick the organism, learn all one can about it from all points of view, and then assess the significance of the findings. Tracy Sonneborn practiced research in very much this way. He would have found virtually every chapter in this volume about Paramecium a fascinating summary of one of his areas of research. Indeed, the beginnings of most of the topics in this book are founded on his studies. With every new fact he learned about Paramecium, he carefully assessed the significance of his findings, not on ly for research on protozoa, but for biology in general. His work, and in a way this book too, are indicative of the success of his strategy.
