Plant seed proteins are small hydrophilic proteins some of which are structurally related. These proteins contain from 83 to 153 amino acid residues and may play a role in equipping the seed for survival, maintaining a minimal level of hydration in the dry organism and preventing the denaturation of cytoplasmic components.[1][2] They may also play a role during imbibition by controlling water uptake.
