General description

Gibberellic acid is a tetracyclic diterpenoid compound, which is synthesized by terpenoid pathway in chloroplasts, cytoplasm, plastid, and endoplasmic reticulum.
Gibberellic acid is an endogenous plant growth regulator

Application

Gibberellic acid has been used as a supplement in Murashige and Skoog media (MS) for treating young leaves of hybrid poplar to follow MYB transcription factor PtrMYB012 expression and in vitro peas seed germination. It has also been used in gibberellic acid (GA)-sensitivity assay in wheat seeds and to promote seed germination in Arabidopsis seeds.
The specific actions of Gibberellin A3 (G1025, G7645) and A4 (G7276) or combinations of Gibberellins should be determined in specific plant applications.

Packaging

1 g in glass bottle

Biochem/physiol Actions

Phytohormone that controls important aspects of plant growth: germination, elongation, and flowering. The effects are mediated by inducing degradation of the DELLA repressor protein, and probably other minor signalling pathways.
Gibberellic acids (GA) are important plant growth hormones that promote plant cell growth and elongation. Gibberellins promote rapid stem and root growth, induce mitotic division and initiate (break dormancy) and increase seed germination rates. The gibberellins are also involved in processes such as gravitropism and flowering.

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. How do I solubilize Gibberellic acid, Product G7645?

    Gibberellic acid is tested for solubility in ethanol (50 mg/ml), yielding a clear, colorless to faint yellow solution.   This may require heating in a water bath for complete solubility.

  4. How is the purity of Gibberellic acid, Product G7645, determined?

    We measure purity by Thin Layer Chromatography, not by HPLC.

  5. How would you recommend that I store a solution of Gibberellic acid, Product G7645?

    This product can be initially dissolved in ethanol, diluted with water and stored at 2-8° C.

  6. Can solutions of Gibberellic acid, Product G7645, be sterilized?

    Yes. Sterilization can be either by filter sterilization or coautoclaving with other media components.

  7. What concentration of Gibberellic acid, Product G7645, should I use with my plant culture?

    Gibberellic acid is used at 0.01 - 5.0 mg/L.
