چکیده مقاله:
During ۲۰۰۷-۲۰۰۸, ۵۸ strains of P. syringae pv. syringae (Pss) were isolated from various
Prunus species and other hosts such as sugar beet, pear, quince, oat, millet, wheat, barley,
and rice in Fars, Isfahan, Kohgiloye and Boyer Ahmad, Chahar Mahal-o-Bakhtiari
provinces of Iran. The strains were tested for pathogenicity, the presence of the syrB gene
and BOX PCR (BOX A۱R primer). All tested Pss strains were pathogenic on peach
seedlings regardless of their original hosts. A total of ۵۸ isolates of the Pss and Pss IVIA
۷۷۳-۱ amplified a ۷۵۲-bp fragment with the syrB primers. The results of analysis of the
BOX fingerprints from P. syringae pv. syringae strains showed that the strains isolated
from stone fruits, graminous hosts and pome fruits formed a relatively distinct cluster,
which were separable from the strains isolated from the other hosts. Results of this study
indicate the existence of a relative degree of host specialization within the heterogeneous
pathovar Pss.
