Abstract: | In 2001, a bacterial rot of onion (Allium cepa L.) bulbs was observed in Japan. The causal agent was identified as Bukholderia cepacia (Palleroni & Holmes 1981 ex Burhkolder 1950) Yabuuchi, Kosako, Oyaizu, Yano, Hotta, Ezaki, and Arakawa 1993. The identified bacteria were divided into two groups (Y and W) based on colony colors, and several phenotypic and genetic characteristics. Based on recA polymerase chain reaction assays, the strains of the Y and W groups belong to genomovar I (B. cepacia sensu stricto) and genomovar III (B. cenocepacia), respectively.The nucleotide sequence data reported are available in the DDBJ/EMBL/GenBank databases under the accession numbers AB162427 and AB162428 |
