MICROBIOLOGY Correction for “Diverse high-torque bacterial flagellar motors assemble wider stator rings using a conserved protein scaffold,” by Morgan Beeby, Deborah A. Ribardo, Caitlin A. Brennan, Edward G. Ruby, Grant J. Jensen, and David R. Hendrixson, which appeared in issue 13, March 29, 2016, of Proc Natl Acad Sci USA (113:E1917–E1926; first published March 14, 2016; 10.1073/pnas.1518952113).
The authors note that, due to a printer’s error, the unit “pN/nm” appeared incorrectly throughout the article and should instead appear as “pN⋅nm.” The online version has been corrected.
