Аннотация: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 the molecular basis of GA action, with the cloning and characterization of GA signaling components. Here, we review the molecular basis of the GA signaling pathway, from the perception of GA to the regulation of downstream genes.
