Fungal Pathogenicity and the Plant's Response

Fungal Pathogenicity and the Plants Response covers the proceedings of the Third Long Ashton Symposium held at Long Ashton Research Station University of Bristol on September 22-24, 1971. Topics for this biennial symposium are decided for their importance to Agriculture and Horticulture and for the timeliness of a critical review of developments in fungal pathogenicity and plants response.
Composed of five sections, this book discusses the direct involvement of fungal proteins in fungal pathogenicity, the role of extracellular enzymes in fruit rotting, and the control of vertical distribution of apple scab disease. It then examines the role of ethylene in plant diseases, growth of obligate parasites, and the concepts of host-pathogen relations. It also focuses on plants induced and preformed resistance factors, including phaseollin, phytoalexin, and benzoic acid. The concluding section discusses the significant role of enzymes, particularly lysosomal enzymes, in fungal pathogenicity.
With a strong focus on original data and speculative comment on host-parasite contact, this book will be helpful for research workers, teachers, and students who wish to broaden their knowledge in fungal pathogenicity.
