RETRACTION
Volume 77, no. 14, p. 4849–4858, 2011, https://doi.org/10.1128/AEM.02599-10. The publisher hereby retracts this article because data in Fig. 2B, 3B, and 5B cannot be supported. It is noted that Beth A. Lazazzera and Henri-Pierre Fierobe were not involved in generating these data. Their contributions were confined to providing training in Bacillus subtilis genetic manipulation and providing plasmid reagents, respectively.
