Gibberellin signaling in plants
Development, 2013The 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’.

A bioassay is described which is dependent upon the fact that gibberellin induced α-amylase release from barley half-seeds is proportional to the logarithm of gibberellin concentration applied. This bioassay has been successfully applied to the estimation of gibberellin-like substances in plant extracts.

Current Opinion in Plant Biology, 1998
Recent findings provide insights into the gibberellin signaling system in plants. Genes for gibberellin biosynthetic enzymes have been cloned, and an emerging theme is that gibberellin biosynthesis is negatively regulated by gibberellin responses.

Science, 1964
Two "gibberellin-like" substances were present in malted wheat, compared to only one in sound, unmalted wheat. Alcoholic extracts of wheat malt fractionated by paper chromatography and bioassayed for gibberellin-like activity by three methods, indicated a new gibberellin in malted wheat.

This review covers recent advances in gibberellin (GA) signaling. GA signaling is now understood to hinge on DELLA proteins. DELLAs negatively regulate GA response by activating the promoters of several genes including Xerico, which upregulates the abscisic acid pathway which is antagonistic to GA.

Chemical conversion of C20 gibberellins into C19 gibberellins
Journal of the Chemical Society, Chemical Communications, 1976Oxidative decarboxylation of ent-gibberellane-19,20-dioic acids with lead tetra-acetate yields mixtures of 19,10- and 20,4-lactones thereby providing a chemical correlation between C20 and C19 gibberellins.

GIBBERELLIN INSENSITIVE DWARF1 encodes a soluble receptor for gibberellin
Nature, 2005Gibberellins (GAs) are phytohormones that are essential for many developmental processes in plants. It has been postulated that plants have both membrane-bound and soluble GA receptors; however, no GA receptors have yet been identified. Here we report the isolation and characterization of a new GA-insensitive dwarf mutant of rice, gid1.
