Erratum to: Dynamic complex formation between HD-GYP, GGDEF and PilZ domain proteins regulates motility in Xanthomonas campestris: c-di-GMP signalling proteins and bacterial motility (Molecular Microbiology, (2012), 86, 3, (557-567), 10.1111/mmi.12000)

The following article from Molecular Microbiology (2012) 86(3), 557–567, ‘Dynamic complex formation between HD-GYP, GGDEF and PilZ domain proteins regulates motility in Xanthomonas campestris’ by Robert P. Ryan, Yvonne McCarthy, Patrick A. Kiely, Rosemary O'Connor, Chuck S. Farah, Judith P. Armitage and J. Maxwell Dow published online in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the authors, the journal Editor-in-Chief, John D Helmann, and John Wiley & Sons Ltd. Since publication of the above article, it has been brought to our attention that there are several image duplications across Figures 3, 5 and 6 including duplication with another article in PNAS: ‘Cell–cell signal-dependent dynamic interactions between HD-GYP and GGDEF domain proteins mediate virulence in Xanthomonas campestris’, by Robert P. Ryan, Yvonne McCarthy, Maxuel Andrade, Chuck S. Farah, Judith P. Armitage, and J. Maxwell Dow; PNAS (2010) 107(13), 5989-5994. The authors apologise for the errors that arose due to poor labelling of the electronic images used in the construction of the figures and for not spotting the duplication during review, and, with agreement of all parties, the decision has been made to retract this article. We apologise for any inconvenience the publication of this work may have caused our readers.
