Description
Control Mechanisms in Developmental Processes covers the proceedings of the 1967 26th Symposium of The Society for Developmental Biology, held in La Jolla, California. This book is divided into three parts encompassing 10 chapters that summarize the role of cytoplasmic units and the nucleus in developmental processes and the regulatory mechanisms. The opening part of the book describes the chemical changes during the development of plastids in leaves of higher plants. The book goes on discussing the nuclear and cytoplasmic controls in Neurospora morphology. This compilation also examines the aspects of development, growth, and control in the basal bodies and flagella of Chlamydomonas reinhardii. The second part describes genetic systems in plants that serve to initiate or program the sequence in plant development and the life cycle of hybrids between somatic cells of different species. A chapter discusses the genetic basis of higher plant morphogenesis by analysis of the differences between genotypes that differ from each other with respect to a single gene having a pronounced and highly specific effect upon form. A discussion on the activation of protein synthesis upon fertilization and early development of animal eggs to the biochemical basis of the determination process is also included. The concluding part deals with the differentiation of erythroid cells; the induction of hemoglobin synthesis; the regulation of heme and globin synthesis; and the role of heme in the synthesis and assembly of hemoglobin. This part also describes the differentiation of cells to the point where they can perform the various types of immunological reactions. This book is an invaluable source for developmental biologists and researchers.
