Gene Manipulations in Fungi combines a review of classical fungal genetics, contemporary research, and responsible speculation about the future. This book focuses on yeasts and molds; because yeast is the primary model system for eukaryotes and that there is an elegant research on molds. The applications of fungi, including their economic importance, are addressed. The book emphasizes the need for improved transformation systems, appropriate vectors, and broadly applicable selectable markers in this field of interest. This book will help stimulate the development of innovative approaches in this subject matter.
