Epidermal cell fate determination in arabidopsis patterns defined by a steroid-inducible regulator

  • The plant epidermis is a single layer of clonally related cells.
  • Plant epidermis fulfils a basic protective function, but specialised cells within the epidermis have specific roles.
  • The seedling epidermis arises by isolation of the outer layer during embryogenesis. The aerial epidermis and the root epidermis originate later, in the shoot apical meristem and in the root apical meristem, respectively.
  • Stomatal guard cells allow gas exchange, and their patterning is controlled by cell‐lineage‐based developmental mechanisms.
  • Trichomes protect the plant from herbivores, and their patterning is controlled by cell–cell interactions.
  • Root hairs increase surface area for water and nutrient uptake, and are patterned according to positional signals.
  • The cuticle overlying the epidermis can contribute to epidermal cell shape and function.
  • There is interplay between the regulation of epidermal cell shape and the regulation of cuticle production.
