The Cereal Rusts, Volume I: Origins, Specificity, Structure, and Physiology presents the historical, evolutionary, taxonomic, structural, genetic, and physiological characteristics of cereal rust fungi and the diseases they cause in cereal crops. The cereal rusts are potentially serious disease threats to cereal crops and have caused widespread losses in wheat, oats, barley, and related crops. This three-part volume brings together in a single reference source the accumulated knowledge, complex, challenging science of cereal rusts. The first chapters of this 16-chapter volume cover the pioneering contributions of early scientists to the knowledge of cereal rusts, the evolution of cereal rusts, and the taxonomy of cereal rust fungi. The book also examines the specificity of cereal rusts including formae speciales, race specificity, pathogen-host genetics, histology and molecular biology of host parasite specificity, and the genetics of rust fungus populations as reflected by virulence frequency. The text further discusses the structure and physiology aspects; the germination of urediospores and differentiation of infection structures; and the infection under artificial conditions. The ultrastructure of hyphae and urediospores; the development and physiology of teliospores; and the obligate parasitism and axenic culture of rust fungi are also explained. This volume also encompasses the structure and physiology of haustoria; structural and physiological alterations in susceptible hosts; and effects of rust on plant development in relation to nutrient translocation.
Cereal rust investigators, plant pathologists, agronomists, agriculturalists, research biochemists, cytologists, geneticists, physiologists, taxonomists, epidemiologists, and pathologists will find this book invaluable.
