Use of rpoB gene phylogenetic marker-based distinction of abiotic stress tolerant and plant-growth promoting Bacillus paralicheniformis isolates from their closely related Bacillus licheniformis

Abstract

Bacillus paralicheniformis is a new identified species, which was distinguished from Bacillus licheniformis in 2015 through extensive phylogenomic and phylogenetic analyses. In this context, this study aimed to achieve a clear identification of the active plant-growth promoting rhizobacteria (PGPR) B. paralicheniformis isolates among the closely related B. licheniformis through molecular typing, helping for the development of clearly-identified PGPR isolates to be used as biofertilizers. A total of 15 rhizobacteria were isolated from the olive rhizosphere
