  • According to this hypothesis, the plant hormone auxin causes induction of the H+ proton extrusion into the apoplast which leads to the activation of expansin which a pH-sensitive protein.
  • Expansin is responsible for wall stretching and relaxation and causes hydrolysis of hydrogen bonds and thus helps in cell expansion.
