Duganella hordei sp. nov., Duganella caerulea sp. nov., and Duganella rhizosphaerae sp. nov., isolated from barley rhizosphere.

ABSTRACT: Duganella sp. strains R1^T, R57^T, and R64^T, isolated from barley roots in Japan, are Gram-stain-negative, motile, rod-shaped bacteria. Duganella species abundantly colonized barley roots. Strains R1^T, R57^T, and R64^T were capable of growth at 4 °C, suggesting adaptation to colonize winter barley roots. Strains R57^T and R64^T formed purple colonies, indicating violacein production, while strain R1^T did not. Based on 16S rRNA gene sequence similarities, strains R1^T, R57^T, and R64^T were most closely related to D. violaceipulchra HSC-15S17^T (99.10%), D. vulcania FT81W^T (99.45%), and D. violaceipulchra HSC-15S17^T (99.86%), respectively
