Genomic Analysis of Plant Pathogenic Bacteria

摘要: This chapter provides an overview of how genome sequence data are changing our understanding the mechanisms and evolution plant pathogenesis, discusses opportunities challenges present for future research. The majority pathogenic bacteria contain large numbers genomic islands, it is clear that in many cases they play essential role disease. Genes encoding P. syringae phytotoxins coronatine syringomycin reside on PIs, as do their recently discovered counterparts E. carotovora subsp. atroseptica SCR1043. Pathogenicity virulence factors have received greatest focus analysis pathogens. Protein secretion systems pathogenesis most been extensively studied, particularly proteobacterial phytohormones indole-3-acetic acid (IAA or auxin) produced by phytopathogenic bacteria. IAA production has shown to contribute planta epiphytic growth, virulence, regulation syringae. Genome analyses pathogens highlighted three aspects physiological adaptation life plants: specialization, innovation, flexibility. A largely uninvestigated element content function pathogen genomes, genomes facultative pathogens, rests what when not causing
