Excerpt from A d104-Book of Mycology and Plant Pathology This book is the outcome of twenty-seven years' experience, as a teacher of botany, during which fifteen years have been given to a graduate course on the morphology, classification and physiology of the fungi, and five years to a course which combined with this consideration a parallel study of the most important cultural and inoculation methods used by the practical bacteriologist and mycologist at the present day. The English and Germans have led in the production of text-books on mycology and pathology; Berkeley, Smith, Cooke and Massee in England, Frank, Sorauer, von Tubeuf and Kuster in Germany. Americans have been behind in this important field, notwithstanding, that American plants harbor some of the most destructive fungi, which, through our careless methods of agriculture and horticulture up to the present, are annually destructive to the extent of millions of dollars. This lack is being rapidly remedied and the appearance of text-books by Duggar, Stevens, Hall and Stevens, Mel T. Cook and general monographs by Erwin T. Smith, and others, augurs well for the future of this line of literary and scientific labor. The bacteriologists have led and mycologists should follow. The following pages represent in a much extended form the lectures and laboratory exercises given by the author before his botanic classes at the University of Pennsylvania, and before public audiences elsewhere, especially, Farmers' Institutes with which he has had three years' experience as a lecturer in Pennsylvania. The arrangement of the text has been suggested by the needs of the classroom and from an acquaintance with similar work in other colleges and universities in America. It is hoped that the book and the suggestions, as to teaching which it contains, will appeal to those responsible for similar courses. The keys are given with the anticipation that they will prove useful to the student and teacher who desire exercises in the classification of the fungi: The illustrations have been chosen with care, and credit is given in all cases for those borrowed from other books and monographs.

The book deals with fungi, deftly defined as “the organisms studied by mycologists”. The fungi are now placed under three kingdoms: Fungi, Protozoa and Chromista/Straminopila due to their phylogenetic heterogeneity. In the last decade, world wide research projects: the “Deep Hypha” and AFTOL (Assembling the Fungal Tree of Life), have provided a phylogenetic classification based on genetic relatedness as evidenced by DNA sequencing data. The ‘Eumycotan fungi’, the ‘Protozoan fungi’ and the ‘Chromistan fungi’ represent distinct monophyletic groups. i.e. each group has a common ancestor and all are its descendants. The classification offered by above mega research projects and accepted by Dictionary of Fungi (2008) and leading international journals, forms the basis of this book. There are many surprises: Fungi and Animalia together form a monophyletic group. But there is no common name for them, and are called as “sister groups”. The mycologists would discover emergence of a new world of ‘modern mycology’ gleaned from recent publications. The book starts with History of Mycology remembering Louis Pasteur’s famous quote “History of science is science itself”. There are 31 chapters describing the form and function of fungi. Their symbiotic associations, chemical activities, secondary metabolites, mycotoxins, heterothallism, parasexuality and sex hormones are described under exclusive chapters. Each chapter is followed by a ‘summary’, and ‘test questions’. The book will be indispensable for students of botany, microbiology, plant pathology and medical mycology.

This book is based on the syllabus prescribed by the Indian Council of Agricultural Research, New Delhi, for the first and second year undergraduate students of plant pathology in State Agricultural and Horticultural Universities and hence, is of special importance to these students. The text, conveniently divided into 13 chapters, deals with fundamental aspects of plant pathology viz., scope and objectives, importance of plant diseases, history and development of plant pathology, theory of plant diseases, causes of plant diseases (biotic, abiotic and plant viruses with representative examples) symptoms, general characteristics of plant pathogens, classification of phytopathogens, growth and reproduction of plant pathogens including replication of plant viruses, liberation or dispersal of plant pathogens, their survival and types of parasitism and variability in plant pathogens. At the end of each chapter, important questions have been provided for the benefit of the students. Diagrams, convincing tables and suitable graphs/illustrations are furnished at appropriate places. A complete bibliography and apt subject index are appended at the end. Besides undergraduate students, this book will also serve as a basic guide to meet the requirement of teachers/researchers in plant pathology and related fields.

Plant Pathology presents information and advances in plant pathology including disease induction and development and disease resistance and control. This book is organized into two major parts encompassing 14 chapters that focus on diseases, pathogenicity, and pathogen variability. The first part of the book deals with general considerations of disease, the disease cycle, parasitism and pathogenicity, and the variability in pathogens. This is followed by a presentation of the mechanisms by which pathogens cause disease and plants resist disease. Core chapters focus on the effects of pathogen-produced enzymes, toxins, growth regulators, and polysaccharides on the structural organization and on the basic physiological processes of photosynthesis, translocation, and respiration. The chapters also discuss the defense mechanisms of the plant. Moreover, this book explains the genetics of host-parasite interaction, effects of environment on disease development, and control. The second part of the book deals with the infectious diseases caused by fungi, bacteria, parasitic higher plants, viruses, and nematodes. This part also looks into the noninfectious diseases caused by environmental factors. The diseases caused by each type of pathogen are discussed comprehensively as a group and are subsequently discussed individually in detail. This book includes diagrams of cycles for each disease to create visual images for better understanding of the disease and message retention. This book is ideal for students with introductory course in plant pathology.
