Root hair development involves asymmetric cell division in Brachypodium distachyon and symmetric division in Oryza sativa.

• The root epidermis of most angiosperms comprises hair (H) cells and nonhair (N) cells. H cells are shorter than N cells in grasses (Poaceae). • The aim of this study was to determine the developmental basis for differences in H and N cell size in the grasses Brachypodium distachyon and Oryza sativ...
