title: Root hair development in grasses and cereals (Poaceae).
abstract: Root hairs are tubular, cellular outgrowths of epidermal cells that extend from the root surface into the soil. Root hairs tether root systems to their growth substrate, take up inorganic nutrients and water, and interact with the soil microflora. At maturity, the root epidermis comprises two cell types; cells with root hairs and hairless epidermal cells. These two cell types alternate with each other along longitudinal files in grasses and cereals (Poaceae). While the mechanism by which this alternating pattern develops is unknown, the later stages of root hair differentiation are controlled by a conserved mechanism that promotes root hair development among angiosperms.
