The layered effect: A single-cell map of corn’s root reveals a regulator of cellular diversity

This article was originally published on this site

A new study uses novel single-cell profiling techniques to reveal how plants add new cell layers that help them resist climate stressors like drought or flooding. The research focuses on corn — a critically important crop around the world — in an effort to create a cell-by-cell map of the plant’s root system, which mediates drought stress and absorbs nutrients and fertilizer from the soil.
