gibberelliinit
Gibberellins are a class of plant hormones that play a crucial role in various aspects of plant growth and development. Discovered in the 1930s by Japanese scientists studying rice blast disease, these compounds were found to be produced by the fungus Gibberella fujikuroi. The term "gibberellins" is now used to refer to this entire group of naturally occurring plant hormones, although the initial discovery was made in a fungal context.
These hormones are diterpenoid compounds, meaning they are synthesized from a precursor molecule called mevalonic acid.
