Other claims from this paper (5)

Observation Subsidiary cell walls form a rim resting on guard cell walls.
Observation Modeling showed guard cell tangential walls bend outward during opening.
Mechanism The rim restricts outward movement of guard cell walls.
Mechanism The rim makes the open pore sink deeper into the epidermis.
Intervention effect The rim makes the pore narrower and more covered than a pore without it.
