Functions of Abscisic Acid
  • Stimulates the closure of stomata (water stress brings about an increase in ABA synthesis).
  • Inhibits shoot growth but will not have as much affect on roots or may even promote growth of roots.
  • Induces seeds to synthesize storage proteins.
  • Inhibits the affect of gibberellins on stimulating de novo synthesis of a-amylase.
  • Has some effect on induction and maintanance of dormancy.
  • Induces gene transcription especially for proteinase inhibitors in response to wounding which may explain an apparent role in pathogen defense.
