The authors discovered that in Table S1, a subset of the C. elegans strain numbers that were listed was incorrect. This does not affect any of the data or conclusions reported in the study, but the correction is necessary for potential strain requests. The supplemental material PDF has been corrected and is available at http://jcb.rupress.org/content/209/4/507/suppl/DC1. The authors apologize for the error.
