Providing an overview of the fundamental aspects of molecular fungal development, this book covers different elements in the maturational and reproductive cycles of selected fungal taxa. Illustrating various molecular pathways in parasites and hosts, the book explores the development of interventional strategies for combating disease. The highlights include: discussions of pseudohyphal yeast growth, hyphal tip growth and genetic control of hyphae fusion, genetic control of aging, spore death, control of the generation of vegetative and sexual reproductive units, symbiotic interactions of fungi with the roots of higher plants, and parasitic interactions of fungi with both plants and animals.
