Specific primers were designed based on the sequences of the spacer region between the 16S and 23S ribosomal DNA (rDNA) for
direct, rapid and specific detection of
Burkholderia gladioli. These primers were named GLA-f and GLA-r. PCR performed on boiled bacterial suspensions yielded an amplification product of
approximately 300 bp. No products from other bacterial species, including
B. glumae were amplified, even after complete DNA extraction by the cetyltrimethyl-ammonium bromide (CTAB) method. Using the specific
primers designed in this study, the PCR method can detect
B. gladioli in plant samples within 6 hr. These data demonstrate the potential of specific PCR for the detection of
B. gladioli.
Key words : Burkholderia gladioli, Burkholderia glumae, rDNA, PCR.
