Background: Bacillus subtilis strains have been widely studied for their innumerous benefits in agriculture, including viticulture. Providing numerous assets, B. subtilis spp. are described as promising plant-protectors against many pathogens and as influencers to adaptations in a changing environment. This study reports the draft genome sequence of the beneficial Bacillus subtilis PTA-271, isolated from the rhizospheric soil of healthy Vitis vinifera cv. Chardonnay at Champagne Region in France, attempting to draw outlines of its full biocontrol capacity.Results: The PTA-271 genome has a size of 4,001,755 bp, with 43.78% of G + C content and 3,945 protein coding genes. The draft genome of PTA-271 putatively highlights a functional swarming motility system hypothesizing a colonizing capacity and a strong interacting capacity, strong survival capacities and a set of genes encoding for bioactive substances. Predicted bioactive compounds are known both to: stimulate plant growth or defenses such as hormones and elicitors, influence beneficial microbiota, and counteract pathogen aggressiveness such as effectors and many kinds of detoxifying enzymes.Conclusions: Plurality of the putatively encoded biomolecules by Bacillus subtilis PTA-271 genome appears as strengths for PTA-271 biocontrol potential towards plants, highlighting a big potential against a broad spectrum of pathogens whatever environmental constraints.
