This book deals with the various aspects viz., the disease, geographical distribution, symptoms on different hosts, host range, yield losses, and disease assessment method, while detailed description on pathogen include taxonomic position, phylogeny, variability, sporulation, perpetuation, and spore germination, host-parasite interactions in the form of seed infection, disease cycle, process of infection, and pathogenesis, epidemiology, forecasting, fine structures, biochemical changes, and phytotoxins, host defence mechanism, techniques to study host-parasite relationships, and management practices including cultural, chemical, biological control practices, and deployment of host resistance. The last section deals with gaps in our understanding, and knowledge about management of these diseases, techniques for the diagnosis of disease and offer suggestions for future research priorities. Each aspect has been vividly illustrated with photographs, histograms, figures, tables, electron micrographs for stimulating, effective and easy reading and understanding. We are sure that this comprehensive encyclopaedic treatise on "Alternaria diseases of crucifers” will be of immense use to the researchers, teachers, students and all others who are interested in the diagnosis and management of Alternaria diseases of crucifers world over. Four species of Alternaria are wide spread and most devastating on cruciferous oil yielding crops, vegetables, forage crops, ornamental plants, and numerous weeds all over the world. The damage to the plants is in the form of infections on seed in the soil during sowing, on seedlings during emergence and growth, on stem, leaves, inflorescence, pods and finally to the seed causing yield losses in seed quantity and quality.

Powdery mildew disease is the fourth most widespread disease in cruciferous crops and a devastating effect, causing significant losses in terms of quality and quantity in rapeseed and mustard. Powdery mildews are also a favourable host-pathosystem model for basic research on host–parasite interactions, developmental morphology, cytology, and molecular biology to identify the effector proteins/genes governing different biological functions. This book provides a comprehensive overview of all the published information in the field for researchers, teachers, students, extension experts, industrialists and farmers, and includes illustrations, photographs, graphs, figures, tables, histograms, micrographs, electron micrographs, and flow charts to aid understanding. It also describes standardized reducible techniques. The book discusses each disease in detail, describing the distribution, symptomatology, host range, yield losses and disease assessment, as well as the taxonomy, morphology, phylogeny, variability, sporulation, survival and perpetuation of the pathogen. Further, it explores topics such as spore germination; infection; pathogenesis; disease cycle; epidemiology; forecasting; fine structures; host resistance; biochemical, histological, genetic and molecular aspects such as cloning and mapping of R genes; sources of resistance; disease resistance breeding; and the genetics of host-parasite interactions and disease management.

The book is presenting a comprehensive information on fundamental, and applied knowledge of Plasmodiophora brassicae Woronin. infecting cruciferous crops, and weeds. Clubroot of crucifers has spread over more than 88 countries of the world with average annual loss of cruciferous crops from 10-15 per cent at global level. It is considered as a disease of cultivation since once introduced in a field, its inoculum piles up year by year in the form of resilient resting spores of P. brassicae which spreads in the field through field operations. This disease is very unique since the pathogen can survive in the soil in the rhizosphere of non-host plants in addition to its main host cruciferous species, cultivated or wild. This book complies inclusive information about the disease, its geographical distribution, symptoms, host range, yield losses, and disease assessment scales. The book also explores host-parasite interactions in the form of seed infection, disease cycle, process of infection, pathogenesis, epidemiology and forecasting. Chapters discuss the genetic and molecular mechanisms of host-parasite relationships, management practices including cultural, chemical, biological control practices, and other integrated approaches. The book is immensely useful to researchers, teachers, extension specialists, farmers, and all others who are interested to grow healthy and profitable cruciferous crops all over the world. Also the book serves as additional reading material for undergraduate and graduate students of agriculture and especially plant pathology. National and international agricultural scientists, policy makers will also find this to be a useful read.

The brassicas include an important group of oilseed crops such as canola and commercial vegetables such as cabbage and broccoli. Infection by species of the fungus Alternaria causes severe yield losses to those crops. This document compiles the most recent information on fundamental and applied knowledge of Alternaria species infecting Brassicaceae crops and weeds. It includes a review of the symptoms, geographical distribution, yield losses, and disease assessment methods of infections from the four most widely distributed species of Alternaria; information on the characteristics of the pathogen, its host range, disease cycle, process of infection, epidemiology, fine structures and electron microscopy, resistance, and phytotoxins; and techniques for disease infection and management. The document concludes with an evaluation of future strategies and priorities in the management of Alternaria diseases.

Biotic stresses cause yield loss of 31-42% in crops in addition to 6-20% during post-harvest stage. Understanding interaction of crop plants to the biotic stresses caused by insects, bacteria, fungi, viruses, and oomycetes, etc. is important to develop resistant crop varieties. Knowledge on the advanced genetic and genomic crop improvement strategies including molecular breeding, transgenics, genomic-assisted breeding and the recently emerging genome editing for developing resistant varieties in oilseed crops is imperative for addressing FPNEE (food, health, nutrition. energy and environment) security. Whole genome sequencing of these crops followed by genotyping-by-sequencing have facilitated precise information about the genes conferring resistance useful for gene discovery, allele mining and shuttle breeding which in turn opened up the scope for 'designing' crop genomes with resistance to biotic stresses. The eight chapters each dedicated to an oilseed crop in this volume elucidate on different types of biotic stress agents and their effects on and interaction with the crop plants; enumerate on the available genetic diversity with regard to biotic stress resistance among available cultivars; illuminate on the potential gene pools for utilization in interspecific gene transfer; present brief on the classical genetics of stress resistance and traditional breeding for transferring them to their cultivated counterparts; depict the success stories of genetic engineering for developing biotic stress resistant varieties; discuss on molecular mapping of genes and QTLs underlying biotic stress resistance and their marker-assisted introgression into elite varieties; enunciate on different emerging genomics-aided techniques including genomic selection, allele mining, gene discovery and gene pyramiding for developing resistant crop varieties with higher quantity and quality of yields; and also elaborate some case studies on genome editing focusing on specific genes for generating disease and insect resistant crops.
