Gibberellic acid is present at a high concentration in the fungus Gibberella fujikuroi, which is the major commercial source for gibberellic acid. Gibberellins are naturally found in plants and some species of fungus and bacteria. This hormone is present in all flowering plants and many non-flowering plants, such as ferns.
The fungus Gibberella fujikuroi, which was first found to alter the growth of Japanese rice plants, is the largest natural source of commercial gibberellic acid extraction. This fungus is cultivated on a large scale in industrial-sized vats, and then extracted through a refinement process causing their stems to become spindly. Another natural source of gibberellins that is cultivated commercially for extraction is Gibberella moniliformis, which affects corn plants.
Gibberellic acid is extracted from the fungus using a method that involves heating the fungus to degrees Fahrenheit. Download citation.

During pollen tube growth, the amount of gibberellin has been shown to increase. Gibberellins also affect male and female fertility in plants. Gibberellic acid plays a role in suppressing female flower formation.
Recent discoveries in botany have led to greater understanding of signaling pathways for gibberellic acids. To get beyond this inhibition, gibberellic acids form a complex that leads to the breakdown of the DELLA growth repressors.
Scientists are still seeking to understand the process for how GAs make all of these things happen. Theoretically, gibberellins must be transporting long distances inside plants. The mechanism for this is not yet clear.
Since plants cannot move, the importance of signaling molecules and hormones is of great importance. This, in turn, will aid agriculture as humans face the need for highly efficient crop yields.
