Gibberellin Metabolism in Maize (The Stepwise Conversion of Gibberellin A12-Aldehyde to Gibberellin A20.
The stepwise metabolism of gibberellin A12-aldehyde (GA12-aldehyde) to GA20 is demonstrated from seedling shoots of maize (Zea mays L.). The labeled substrates [13C,3H]GA12-aldehyde, [13C,3H]GA12, [14C4]GA53, [14C4/2H2]GA44, and [14C4/2H2]GA19 were fed individually to dwarf-5 vegetative shoots. Both [13C,3H]GA12-aldehyde and [13C,3H]GA12 were also added individually to normal shoots. The labele...
متن کاملGibberellin homeostasis in tobacco is regulated by gibberellin metabolism genes with different gibberellin sensitivity.
Gibberellins are phytohormones that regulate growth and development of plants. Gibberellin homeostasis is maintained by feedback regulation of gibberellin metabolism genes. To understand this regulation, we manipulated the gibberellin pathway in tobacco and studied its effects on the morphological phenotype, gibberellin levels and the expression of endogenous gibberellin metabolism genes. The o...
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 کاملGibberellin 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 کاملGibberellin metabolism and signaling.
Gibberellins (GAs) are a family of plant hormones controlling many aspects of plant growth and development including stem elongation, germination, and the transition from vegetative growth to flowering. Cloning of the genes encoding GA biosynthetic and inactivating enzymes has led to numerous insights into the developmental regulation of GA hormone accumulation that is subject to both positive ...
