The study focused on understanding how the PGPR strain Bacillus atrophaeus UCMB-5137 regulates genes during interactions with plants, specifically in response to root exudates.
The gene regulation observed in B. atrophaeus differed from the well-studied B. amyloliquefaciens FZB42, with UCMB-5137 showing heightened sensitivity to root exudates, suggesting a unique colonization strategy.
The research identified potential roles of non-coding RNA and other regulatory factors in this process, highlighting gaps in our knowledge about gene regulation networks in Bacillus species.
Bacillus atrophaeus UCMB-5137 shows an extraordinary activity in root colonization and plant and crop protection. Its draft genome sequence comprises 21 contigs of 4.11 Mb, harboring 4,167 coding sequences (CDS).
