Fastidious Vascular-Colonizing Bacteria
Quote:Quote:Most phytopathogenic bacteria invade their host plants through natural openings or wounds, colonizing intercellular spaces, expressing virulence factors and inducing various host plant responses. A few, however, are introduced directly into the sugar-rich phloem sieve tubes or into the water-transporting xylem elements by vascular-feeding insects.
Quote:Their location within living (sieve tubes) or degenerated (xylem elements) plant cells, rather than in intercellular spaces, offers different challenges and opportunities for them to avoid the host plant's defense system. In addition, many of the plant vascular-inhabiting bacteria establish intimate relationships. These relationships may be beneficial or deleterious with the insects that transmit them from plant to plant.
