Cytosolic 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 کاملThe DELLA domain of GA INSENSITIVE mediates the interaction with the GA INSENSITIVE DWARF1A gibberellin receptor of Arabidopsis.
Gibberellic acid (GA) promotes seed germination, elongation growth, and flowering time in plants. GA responses are repressed by DELLA proteins, which contain an N-terminal DELLA domain essential for GA-dependent proteasomal degradation of DELLA repressors. Mutations of or within the DELLA domain of DELLA repressors have been described for species including Arabidopsis thaliana, wheat (Triticum ...
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...

متن کاملRice GIBBERELLIN INSENSITIVE DWARF1 is a gibberellin receptor that illuminates and raises questions about GA signaling.
Recently, gibberellins (GAs) joined the list of plant hormones with a known receptor protein with the report by UeguchiTanaka et al. (2005) that the GIBBERELLIN INSENSITIVE DWARF1 (GID1) protein of rice has the expected properties of the long-sought GA receptor. This exciting discovery not only provides a major new piece to the puzzle of the GA signal transduction pathway but also raises new qu...
