Double-Wing Motif Protein is a Novel Biofilm Regulatory Factor of the Plant Disease Biocontrol Agent, .

Transposon mutagenesis screening of YB-1471, a novel rhizosphere biocontrol agent of Fusarium crown rot (FCR) of wheat, resulted in the identification of , linked to reduced biofilm formation. The gene encodes a protein possessing a putative tertiary structure of a "double-wing" DNA-binding domain. Expression of increased during biofilm development in stationary cultures and during rapid growth in shaking cultures.

Isolation and Genome-Based Characterization of Biocontrol Potential of YB-1631 against Wheat Crown Rot Caused by .

Fusarium crown rot (FCR) caused by is one of the most serious soil-borne diseases of wheat. Among 58 bacterial isolates from the rhizosphere soil of winter wheat seedlings, strain YB-1631 was found to have the highest in vitro antagonism to growth. LB cell-free culture filtrates inhibited mycelial growth and conidia germination of by 84.

Response of to Biocontrol Agent YB-185 by Phenotypic and Transcriptome Analysis.

The use of biological control agents (BCAs) is a promising alternative control measure for Fusarium crown rot (FCR) of wheat caused by . A bacterial strain, YB-185, was isolated from the soil of wheat plants with FCR and identified as . YB-185 exhibited strong inhibition of mycelial growth and conidial germination in culture.
