Keyword - Gibberellin signaling pathway (KW-0939)


Protein involved in the gibberellin (GA) signaling pathway (e.g. transport and signal transduction) that regulates many aspects of plant growth including seed germination, hypocotyl elongation, stem elongation, leaf expansion, trichome development, pollen maturation and flower and fruit development. GAs are tetracyclic diterpenoid phytohormones found in plants, fungi and bacteria. They are named GA1....GAn in order of discovery. The term "gibberellin" was first given to a substance, produced by the fungus Gibberella fujikuroi, which caused overgrowth symptoms in rice. This substance was later proven to be a mixture of GAs, with GA1 and GA3 being the active factors.
