In seeds, ABA promotes seed development, embryo maturation, Synthesis of storage products (proteins and lipids), desiccation Tolerance, is involved in maintenance of dormancy (inhibition of Germination), and apoptosis. As well, ABA affects plant Architecture, including root growth and morphology, and
Root-to-shoot ratios.

The following are some of the phyysiological responses known to Be associated with 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 miaintanance of dormancy.
Induces gene transcription especially for proteinase inhibitors in response to wounding which may explain an apparent role in pathogen defense.
