Isolated Bacillus subtilis strain 330-2 and its antagonistic genes identified by the removing PCR.

ABSTRACT: Plant growth-promoting bacteria (PGPB) may trigger tolerance against biotic/abiotic stresses and growth enhancement in plants. In this study, an endophytic bacterial strain from rapeseed was isolated to assess its role in enhancing plant growth and tolerance to abiotic stresses, as well as banded leaf and sheath blight disease in maize. Based on 16S rDNA and BIOLOG test analysis, the 330-2 strain was identified as Bacillus subtilis. The strain produced indole-3-acetic acid, siderophores, lytic enzymes and solubilized different sources of organic/inorganic phosphates and zinc. Furthermore, the strain strongly suppressed the in vitro growth of Rhizoctonia solani AG1-IA, Botrytis cinerea, Fusarium oxysporum, Alternaria alternata, Cochliobolus heterostrophus, and Nigrospora oryzae.
