Analysis of the Complete Genome Sequence of Bacillus atrophaeus GQJK17 Reveals Its Biocontrol Characteristics as a Plant Growth-Promoting Rhizobacterium

الملخص EN

Bacillus atrophaeus GQJK17 was isolated from the rhizosphere of Lycium barbarum L.

in China, which was shown to be a plant growth-promoting rhizobacterium as a new biological agent against pathogenic fungi and gram-positive bacteria.

We present its biological characteristics and complete genome sequence, which contains a 4,325,818 bp circular chromosome with 4,181 coding DNA sequences and a G+C content of 43.3%.

A genome analysis revealed a total of 8 candidate gene clusters for producing antimicrobial secondary metabolites, including surfactin, bacillaene, fengycin, and bacillibactin.

Some other antimicrobial and plant growth-promoting genes were also discovered.

Our results provide insights into the genetic and biological basis of B.

atrophaeus strains as a biocontrol agent for application in agriculture.
