Bacillus niabensis sp. nov., isolated from cotton-waste composts for mushroom cultivation.

A group of five bacilli, designated strains 4T12, 4T19(T), 5M45, 5M53 and 5T52, isolated from cotton-waste composts for mushroom cultivation, were examined. These strains were Gram-positive, aerobic, motile, spore-forming rods. 16S rRNA gene sequence analyses revealed that the isolates belonged to the genus Bacillus, showing the highest levels of similarity (approx.

Construction of a bacterial artificial chromosome library and characterization of hrp/hrc gene cluster of Pseudomonas syringae pathovar tagetis LMG5090.

Pseudomonas syringae pv. tagetis causes apical chlorosis of several plant species in the Asteraceae, including marigold. As a means to facilitate the isolation of pathogenicity genes and to characterize the genome of this bacterium, we have constructed a bacterial artificial chromosome library of P.

The genome sequence of Xanthomonas oryzae pathovar oryzae KACC10331, the bacterial blight pathogen of rice.

The nucleotide sequence was determined for the genome of Xanthomonas oryzae pathovar oryzae (Xoo) KACC10331, a bacterium that causes bacterial blight in rice (Oryza sativa L.). The genome is comprised of a single, 4 941 439 bp, circular chromosome that is G + C rich (63.

Phylogenetic analysis of the genera Bradyrhizobium, Mesorhizobium, Rhizobium and Sinorhizobium on the basis of 16S rRNA gene and internally transcribed spacer region sequences.

A total of 128 strains was isolated from more than 23 legume hosts in Korea. Phylogenetic relationships between these Korean isolates and reference strains of the genera Bradyrhizobium, Mesorhizobium, Rhizobium and Sinorhizobium were analysed using their 16S rRNA gene and internally transcribed spacer (ITS) region sequences. Among the Bradyrhizobium strains, dendrograms based on both the 16S rRNA gene and ITS region sequences produced two main groups.

Sensitive and specific detection of Xanthomonas campestris pv campestris by PCR using species-specific primers based on hrpF gene sequences.

A sensitive and specific assay was developed to detect bacterial black rot of crucifers caused by Xanthomonas campestris pv. campestris (X. c.
