Correction to: Nature Plants https://doi.org/10.1038/s41477-017-0092-7, published online 29 February 2018.

In the version of this Article originally published, the authors incorrectly labelled the timescale in Fig. 6b as milliseconds (ms) on the x axis and the indicated half-life values; the correct units are microseconds (μs). The figure has now been amended in all versions of the Article.
