Editorial. Counting what counts: quantitative approaches in plant cell biology (COPB)

In the new Cell Biology issue of Current Opinion in Plant Biology, editors Haswell and Dixit have chosen to focus on quantitative cell biology, arguing that, “if seeing is believing, then measuring is knowing.” Topics of the issue’s reviews span parts of the cell (including cell wall, cytoskeleton, stromules), things cells do (including morphogenesis) and tools and models (including optical tweezers, Chlamydomonas, Physcomitrella, and guard cells). You can find all of the articles in this issue here. (Summary by Mary Williams) Curr. Opin. Plant Biol. 10.1016/j.pbi.2018.10.003
