Extended Data Fig. 7: With different sets of turgor pressure, stiffer polar materials still result in smaller stomatal pore width.
From: Esterified-pectin-coupled polar stiffening controls grass stomatal opening

a, Stomatal pore width with different turgor pressures of GCs. Ratio of turgor pressure between GCs and SCs was maintained at 2/0.35. b, Stomatal pore width with different turgor pressures of SCs. Turgor pressure of GCs was maintained at 2 MPa.
