Complete genome sequence of Bacillus amyloliquefaciens L-H15, a plant growth promoting rhizobacteria isolated from cucumber seedling substrate.

Bacillus amyloliquefaciens L-H15 is a plant growth promoting rhizobacteria (PGPR) isolated from the cucumber seedling substrate collected in Beijing, China. The complete genome of B. amyloliquefaciens L-H15 consists of one single circular chromosome (3,864,316 bp) without any plasmid. From the genome, we identified clusters responsible for non-ribosomal synthesis of secondary metabolites, and genes related to the plant growth promotion hormone such as indole-3-acetic acid (IAA) and acetoin secretion. In addition, genes that contribute to biofilm formation were also found on the genome of L-H15. Complete genome information enables further study on the beneficial interactions between B. amyloliquefaciens L-H15 and host plants, and the future application of B. amyloliquefaciens L-H15 as biofertilizer and biocide.
