Gibberellin receptor and its role in gibberellin signaling in plants.
Gibberellins (GAs) are a large family of tetracyclic, diterpenoid plant hormones that induce a wide range of plant growth responses. It has been postulated that plants have two types of GA receptors, including soluble and membrane-bound forms. Recently, it was determined that the rice GIBBERELLIN INSENSITIVE DWARF1 (GID1) gene encodes an unknown protein with similarity to the hormone-sensitive ...
متن کاملCytosolic activity of the gibberellin receptor GIBBERELLIN INSENSITIVE DWARF1A.
Arabidopsis has three gibberellin receptors, GIBBERELLIN INSENSITIVE DWARF1 A (GID1A), GID1B and GID1C. All GID1s are localized to the nucleus but have also been detected in the cytoplasm. Since other major gibberellin signaling components have been localized to the nucleus, the current model suggests that gibberellin perception and signaling is nuclear. In this work we investigated whether GID...
متن کاملStructural Basis for Gibberellin Recognition by Its Receptor GID 1 Life Science : Structural Biology
Gibberellins are a large family of tetracyclic diterpenoid plant hormones that induce a wide range of plant growth responses including seed germination, stem elongation, leaf expansion, pollen maturation and induction of flowering. Gibberellins were first discovered by a Japanese plant pathologist, Eiichi Kurosawa, from the pathogenic fungus Gibberella fujikuroi in 1926 [1]. Kurosawa was workin...
متن کاملGibberellin biosynthesis and its regulation.
The GAs (gibberellins) comprise a large group of diterpenoid carboxylic acids that are ubiquitous in higher plants, in which certain members function as endogenous growth regulators, promoting organ expansion and developmental changes. These compounds are also produced by some species of lower plants, fungi and bacteria, although, in contrast to higher plants, the function of GAs in these organ...
متن کاملProteolysis-independent downregulation of DELLA repression in Arabidopsis by the gibberellin receptor GIBBERELLIN INSENSITIVE DWARF1.
This article presents evidence that DELLA repression of gibberellin (GA) signaling is relieved both by proteolysis-dependent and -independent pathways in Arabidopsis thaliana. DELLA proteins are negative regulators of GA responses, including seed germination, stem elongation, and fertility. GA stimulates GA responses by causing DELLA repressor degradation via the ubiquitin-proteasome pathway. D...
