Nat. Biotechnol.; 10.1038/nbt.4232; corrected online 23 October 2018

In the version of this article initially published online, the citations to Supplementary Figures 12a and 12b were interchanged in section “TRM1 and disease resistance” and the last sentence of Results referred to the rhizosphere of Hawaii 7996; it should have referred to that of Moneymaker pretreated with TRM1-10. The error has been corrected in the print, PDF and HTML versions of this article.
