Abscisic Acid (ABA)

Abscisic Acid (ABA)

What is Abscisic Acid?

  • Glands are organs that secrete hormones at different times to stimulate body processes such as growth, development, and the breaking down of sugars.
  • Abscisic acid is a plant hormone involved in many developmental plant processes, such as dormancy and environmental stress response.

The function of Abscisic Acid

  • Plants have openings on the bottom side of their leaves, known as stomata.
  • Stomata take in carbon dioxide and regulate water content.
  • Abscisic acid has been found to function in the closing of these stomata during times when the plant does not require as much carbon dioxide or during times of drought when the plant cannot afford to lose much water through transpiration.
  • ABA functions in many plant developmental processes, including seed and bud dormancy, the control of organ size and stomatal closure.
  • It is important for plants in the response to environmental stresses, including drought, soil salinity, cold tolerance, freezing tolerance, heat stress and heavy metal ion tolerance.
