Webb110). This relative inaccessibility means that the phloem is not easily invaded and, as a result, many phloem pathogens are vectored by insects. The plant responds to the invasion, of course, and defense mechanisms can be effective, but the phloem is itself an escape route; many mobile pathogens migrate along the sieve tubes, out of harm’s way.
