In Erwinia amylovora, the dsp region, required for pathogenicity on the host plant but not for hypersensitive elicitation on tobacco, is separated from the hrp region by 4 kb. The genetic analysis reported in this paper showed that this 4kb region is not required for pathogenicity on pear seedlings. The environmental conditions allowing expression of a dsp… CONTINUE READING
