Description
The study of vector biology encompasses a multitude of diverse aspects and levels of pursuit, each one required separately and then collaboratively with the others to explain holistically a range of vector host-finding, feeding or ingestion, and dispersal activities, among a plethora of other behaviors, including response to plant volatiles, phytochemicals, and physical factors. At another level, vector biologists characterize the behaviors of insects and their mouthparts at the host plant surface interface, while others investigate the complex external and internal anatomies of the vector using, in some instances, noninvasive electropenetration waveforms that characterize stylet penetration, salivation, ingestion of cellular contents, and inoculation of plant pathogens that result in pathogen transmission to the host. Others elucidate molecular-, cellular-, and functional genomics-level features and characteristics of pathogen effectors and determinants of specificity and their interactions with host proteins or other kinds of interactor molecules that culminate in successful passage through the vector and return to the plant host. In recent decades, clearly much has been learned about mechanistic aspects of these interactions at different levels of completeness and extents of complexity; however, because of the recalcitrant nature of these multitrophic biological systems, much more remains to be learned.
This book is organized into seven parts, each addressing a distinct area of focus in plant pathogen–vector biology. Part 1 sets the stage by providing insights into biochemical, genetic, and genomic considerations by exploring mechanistic parameters of chemical ecological roles in vector-mediated virus transmission, followed by a perspective ensuing from the piecing together of fine-level, coordinated functional genomics–physiological–biochemical analyses of interactions that govern the phytoplasma pathogen metabolic pathway genes that characterize the leafhopper–phytoplasma infection cycle.
Parts 2–6 cover systematically the interactions that govern each of the main modes of vector-mediated transmission in the context of a pathogen’s coevolved interactions with particular anatomical structures of each type of vector and the defined pathway and specificity of the retention–inoculation characteristics. Pathogens discussed in these sections include Eubacteria, including free-living and fastidious life styles, fungi and organisms once classified as fungal pathogens, plant-pathogenic nematodes, and plant RNA and DNA viruses, some that infect only the plant host and others that replicate in both a plant and an animal (vector) host. The vectors themselves span arthropods, represented by insects with a variety of host-feeding tropisms and bearing diverse mouthpart types, to mites, fungi (including chytrids), organisms once classified as fungal pathogens, nematodes, and trypanosomatids. Each chapter discusses a best-studied plant pathogen–biological vector example of the particular mode and associated anatomical locus, bringing together many years of research that has been undertaken to advance the understanding of pathogen–vector biology and these interactions at biochemical, cellular–tissue–organ, and functional genomics levels for which such information is currently available. Among these are noncirculative stylet-borne or mouthpart-borne (nonpersistent), noncirculative foregut-borne (semipersistent), noncirculative foregut-borne (persistent), circulative (persistent), nonpropagative circulative (persistent), and persistent propagative pathogen–vector complexes. This is an intriguing range of relationships recognized to occur among pathogen–vector complexes and perhaps does not yet represent all of the possibilities!
In Part 7, short treatises are presented that cover a number of emerging pathogen–vector complexes about which much more information is needed to elucidate the vector biology to a level that rational approaches may become possible to address the new, poorly recognized, or previously unrecognized plant-pathogen vectors and the constraints they pose to agriculture.
