Bacillus cabrialesii : Five Years of Research on a Novel Species of Biological Control and Plant Growth-Promoting Bacteria.

Bacillus cabrialesii is a novel bacterial species isolated from wheat ( Triticum turgidum L. subsp. durum ) plants in the Yaqui Valley, Mexico, by our research team. Over years of research studying this strain at the cutting-edge level, it has shown different mechanisms of action. B. cabrialesii is strongly reported as a plant-growth-promoting bacterium and a biological control agent on wheat crops. Knowing this, B. cabrialesii has been brought from lab to field as part of a bacterial consortium, not to mention that there are ongoing investigations into formulating a cost-effective bioinoculant to increase the yield and/or quality of wheat. Moreover, studies of this novel species as a biocontrol agent in other crops (pepper, tomato, cucumber, and potato) are being carried out, with preliminary results that make B. cabrialesii a promising biological control agent, inhibiting the growth of phytopathogens. However, research into this bacterium has not only been reported in our country; there are many studies around the world in which promising native Bacillus strains end up being identified as B. cabrialesii , which reaffirms the fact that this bacterial species can promote plant growth and combat phytopathogens, showing great agrobiotechnological potential.
