Gibberellin 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 ...
متن کاملUpdate on Gibberellin Signaling
Bioactive gibberellins (GAs) are plant hormones that control growth and development throughout the life cycle of the plant. Isolation and characterization of mutants that are impaired in GA biosynthesis have been crucial in both understanding the role of GAs in regulating plant development and elucidating the GA biosynthetic pathway (Davies, 1995; Hedden and Phillips, 2000). The broad spectrum ...
متن کاملGibberellin signaling in plants.
The plant hormone gibberellin (GA) regulates major aspects of plant growth and development. The role of GA in determining plant stature had major impacts on agriculture in the 1960s, and the development of semi-dwarf varieties that show altered GA responses contributed to a huge increase in grain yields during the 'green revolution'. The past decade has brought great progress in understanding t...
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 Signaling: GRASs Growing Roots Dispatch
Gibberellins are a class of terpenoid molecules that can act as plant growth regulators. This class was discovered through the investigation of sick rice plants that were infested by the fungus Gibberella fujikuroi. In 1926, Eiichi Kurosawa determined that a substance, dubbed gibberellic acid, secreted by the fungus was causing the disease. Subsequently, it was realized that gibberellic acid is...
