Interpretive Summary:

Technical Abstract: The revolution in DNA sequencing technology has led to and improved understanding of genetics and taxonomy of biocontrol agents. Our lab recently reported the genomes of some important Bacillus bacterial biocontrol agents, which in turn resulted in a change of taxonomy for these commercially important strains. Our study showed that four species of Bacillus (Bacillus amyloliquefaciens subsp. plantarum, Bacillus methylotrophicus, Bacillus oryzicola and Bacillus velezensis) are the same species. Under the rules of prokaryote taxonomy, the name of the first described species takes precedent over the other names. In this case, Bacillus velezensis, is the correct nomenclature for these strains. This class of Bacillus strains is the second most popular commercial prokaryotic biocontrol agents after Bacillus thuringiensis. In addition, our knowledge of what defines a given “species” has greatly changed in the last five years. Now correctly identifying your strains can directly provide more information about the physiology and phenotype of your strain.
