The Biochemistry of Plants, Volume 15: Molecular Biology presents information pertinent to gene expression, cytoskeletal proteins, and hydroxyproline-rich glycoprotein. This book discusses the specific gene systems and examines the regulatory regions within the genes. Organized into 17 chapters, this volume starts with an overview of the important mechanism for regulating gene expression, which is significant in the selective turnover of gene products. This book then proceeds with a discussion of the concept of protein degradation and the extracellular carriers of genetic information. Other chapters review the viral and plasmid systems, which are relevant to plants. This text discusses as well the phenotypic changes in plants, including plant genetic tumor and habituated plant tissues that exhibit hormone autotrophic growth. The final chapter examines the importance of genetic manipulation at the cellular level via protoplast fusion, cell selection, and transformation. Biologists, biochemists, enzymologists, biophysicists, and plant scientists will find this book extremely useful.
