摘要: This chapter focuses on the pathogenicity determinants of Pseudomonas syringae as a paradigm for microbial pathogenesis in plants. It specifically upon genetic P. strains necessary colonization plant tissue. As mammalian pathogens, essential several plant-pathogenic bacteria are localized apparent islands (PAIs). Proteins translocated by type III protein translocation complex (PTC) similar to that its counterparts mediate both and host range strains. Hybridization analysis indicates all carry homolog HrpW is present closely related Erwinia hrp cluster. The pectate lyase-like domain was most highly conserved region from two organization clusters regulatory mechanisms controlling environmental regulation clearly distinct between groups hrp clusters. For example, primary factor X. campestris R. solanacearum hrp an AraC (HrpX HrpB, respectively. By analogy pathogenic bacteria, such syringae, probably involves (i) adhesion cells, (ii) activation PTC, (iii) into (iv) physiological changes cells stimulate release nutrients, (v) production virulence factors facilitate growth (vi) spread surrounding
