Molecular characterization of a novel strain of Bacillus halotolerans protecting wheat from sheath blight disease caused by Rhizoctonia solani Kuhn.

ABSTRACT: Rhizoctonia solani Kühn naturally infects and causes Sheath blight disease in cereal crops such as wheat, rice and maize, leading to severe reduction in grain yield and quality. In this work, a new bacterial strain Bacillus halotolerans LDFZ001 showing efficient antagonistic activity against the pathogenic strain Rhizoctonia solani Kühn sh-1 was isolated. Antagonistic, phylogenetic and whole genome sequencing analyses demonstrate that Bacillus halotolerans LDFZ001 strongly suppressed the growth of Rhizoctonia solani Kühn sh-1, showed a close evolutionary relationship with B. halotolerans F41-3, and possessed a 3,965,118 bp circular chromosome. Bioinformatic analysis demonstrated that the genome of Bacillus halotolerans LDFZ001 contained ten
