Plant-pathogen Interactions


Book Description

Plant diseases are destructive and threaten virtually any crop grown on a commercial scale. They are kept in check by plant breeding strategies that have introgressed disease resistance genes into many important crops, and by the deployment of costly control measures, such as antibiotics and fungicides. However, the capacity for the agents of plant disease - viruses, bacteria, fungi, and oomycetes - to adapt to new conditions, overcoming disease resistance and becoming resistant to pesticides, is very great. For these reasons, understanding the biology of plant diseases is essential for the development of durable control strategies. Plant-Pathogen Interactions provides and overview of our current knowledge of plant-pathogen interactions and the establishment of plant disease, drawing together fundamental new information on plant infection mechanisms and host responses. The role of molecular signals, gene regulation, and the physiology of pathogenic organisms are emphasized, but the role of the prevailing environment in the conditioning of disease is also discussed. Emphasizing the broader understanding that has emerged from the use of molecular genetics and genomics, Plant-Pathogen Interactions highlights those interactions that have been most widely studied and those in which genome information has provided a new level of understanding.




The plant microbiome and its importance for plant and human health


Book Description

The study of plant-microbe associations by new techniques has significantly improved our understanding of the structure and specificity of the plant microbiome. Yet, microbiome function and the importance of the plant’s microbiome in the context of human and plant health are largely unexplored. Comparable with our human microbiome, millions of microbes inhabit plants, forming complex ecological communities that influence plant growth and health through its collective metabolic activities and host interactions. Viewing the microbiota from an ecological perspective can provide insight into how to promote plant health and stress tolerance of their hosts or how to adapt to a changing climate by targeting this microbial community. Moreover, the plant microbiome has a substantial impact on human health by influencing our gut microbiome by eating raw plants such as lettuce and herbs but also by influencing the microbiome of our environment through airflow. This research topic comprising reviews, original and opinion articles highlights the current knowledge regarding plant microbiomes, their specificity, diversity and function as well as all aspects studying the management of plant microbiomes to enhance plant growth, health quality and stress tolerance.

Biopesticides may be microbial (nematodes, bacteria, fungi, virus, herbs etc.), plant-incorporated protectants (PIPs), plant products (citronella oil, neem oil, capsaicin, pyrethrin etc.), synthetic biochemical molecules, pheromones, semio-chemicals, plant extracts, or nanobiopesticides. - Includes emerging areas of nanobiopesticides, chemical aspects of biopesticides and plant exudates - Presents strategies for researching nematodal biological control - Addresses problems related to the mass production, manufacture and formation of biopesticides from both animal and plant products




Geminivirus: Detection, Diagnosis and Management


Book Description

Geminivirus: Detection, Diagnosis and Management focuses on the latest techniques for managing diseases caused by these circular, single-stranded (ss) DNA genomes. The most significant impact of plant diseases in host populations is often caused by emerging diseases, whose incidence in a plant host is increasing as a result of long-term changes in their underlying epidemiology. Genetic changes in pathogen and host populations, as well as changes in host ecology and environment, are major factors contributing to disease emergence. Understanding plant virus evolution is crucial for modeling the within-host and between-host dynamics and genetics of virus populations. The book presents a comprehensive review of how these viruses develop, including contributing factors such as population bottlenecks during cell-to-cell movement, systemic colonization, or between-host transmission by different procedures. Presented in five sections—Detection and Diagnosis, Emergence and Diversity, Vector and Transmission, Virus–Host Interaction, and Disease Management, the book includes host range determinant and virulence factors involved in pathogenesis, virus–vector interactions during acquisition, retention, and transmission and evaluating management strategies to control Geminivirus. The book is an essential reference for students and researchers interested in plant virology, particularly begomoviruses, geminiviruses, and vector transmission biology. - Introduces identification and characterization of geminiviruses that infect agricultural crops, their wild relatives, and weed hosts - Discusses recombination and reassortment mechanisms influencing viral genetic diversity, virulence, and vector transmission - Explores the origin, evolution, and bottlenecks of Geminiviruses - Introduces identification and characterization of geminiviruses that infect agricultural crops, their wild relatives, and weed hosts - Discusses recombination and reassortment mechanisms influencing viral genetic diversity, virulence, and vector transmission - Explores the origin, evolution, and bottlenecks of Geminiviruses

Diagnosing Hemp and Cannabis Crop Diseases


Book Description

Hemp and cannabis, both belonging to Cannabis sativa, have emerged as some of the most valuable crops because of their multiple functionalities - industrial, medicinal, and recreational uses. Like all other crops, they are at risk of diseases and pests. In certain cases, an entire hemp field can fail due to unexpected disease. As a new and highly regulated crop, research on Cannabis crop diseases is scarce, and the science of plant diagnostics is not well covered in the literature. Taking hemp/cannabis as a model crop, the book illustrates how to diagnose a disease problem and how to manage it effectively. It presents real disease cases encountered during crop production, and explains methods of diagnosis, both in the field and in the lab, in order to find out the cause(s).




Plant Tolerance to Environmental Stress


Book Description

Global climate change affects crop production through altered weather patterns and increased environmental stresses. Such stresses include soil salinity, drought, flooding, metal/metalloid toxicity, pollution, and extreme temperatures. The variability of these environmental conditions pared with the sessile lifestyle of plants contribute to high exposure to these stress factors. Increasing tolerance of crop plants to abiotic stresses is needed to fulfill increased food needs of the population. This book focuses on methods of improving plants tolerance to abiotic stresses. It provides information on how protective agents, including exogenous phytoprotectants, can mitigate abiotic stressors affecting plants. The application of various phytoprotectants has become one of the most effective approaches in enhancing the tolerance of plants to these stresses. Phytoprotectants are discussed in detail including information on osmoprotectants, antioxidants, phytohormones, nitric oxide, polyamines, amino acids, and nutrient elements of plants. Providing a valuable resource of information on phytoprotectants, this book is useful in diverse areas of life sciences including agronomy, plant physiology, cell biology, environmental sciences, and biotechnology.
