Isolation and genomic characterization of six endophytic bacteria isolated from Saccharum sp (sugarcane): Insights into antibiotic, secondary metabolite and quorum sensing metabolism

J Genomics. 2018 Oct 2:6:117-121. doi: 10.7150/jgen.28335. eCollection 2018.


Six endophytic bacteria were isolated from Saccharum sp (sugarcane) grown in the parish of Westmoreland on the island of Jamaica located in the West Indies. Whole genome sequence and annotation of the six bacteria show that three were from the genus Pseudomonas and the other three were from the genera Pantoea, Pseudocitrobacter, and Enterobacter. A scan of each genome using the antibiotics and secondary metabolite analysis shell (antiSMASH4.0) webserver showed evidence that the bacteria were able to produce a variety of secondary metabolites. In addition, we were able to show that one of the organisms, Enterobacter sp RIT418 produces N-acyl-homoserine lactones (AHLs), which is indicative of cell-cell communication via quorum sensing (QS).
