This book describes how genomics has revolutionized our scientific
understanding of agriculturally important plant-associated bacteria.
Each chapter focuses on the genomics of particular bacteria: the first
described plant pathogen, Erwinia amylovora; phytoplasmas lacking cell
walls; fastidious, phloem-restricted liberibacters; Pseudomonas
syringae, which is a genetically tractable model system; Xanthomonas
citri, which causes a disease that can devastate citrus crops and
Pseudomonas fluorescens, which can protect plants from diseases.
Topics considered in this volume include the importance of horizontal
gene transfer in originating new bacterial strains and species and
advances in transcriptomics that allow us to describe the complex
regulatory networks critical to plant-microbe interactions. The
availability of the Xanthomonas oryzae genome has led to new
technologies in genome editing, which will revolutionize approaches to
genetic engineering, even in eukaryotes. The contributions show how
genomics has greatly accelerated progress toward understanding the
biology of these bacteria and how that understanding can be translated
into novel crop protection methods.
