Critical Reviews in Biotechnology, 1991
AbstractGibberellins are a classic example of the production of plant growth regulators by microorganisms. They are important biotechnological products and are increasingly used in agriculture and horticulture.This article intends to assemble information on the history of the identification of gibberellins (GA) and producing microorganisms, especially ...

The occurrence of gibberellins and gibberellin-like substances in algae
Phycologia, 1977Abstract The present status of work on gibberellins and gibberellin-like substances in algae has been reviewed in the light of recent developments in research on higher plants. We emphasize the needs to develop specific algal bioassays, and to establish the chemical identity of gibberellins which are indigenous to algae.

Activity of synthetic gibberellin A15 and (±)-gibberellin A15isolactone
Phytochemistry, 1974Abstract The activities of (±)-gibberellin A15 ((±)-GA15) and (±)-gibberellin A15-isolactone ((±)-iso-GA15) which were obtained by stereocontrolled total synthesis and gibberellin A15 (E-GA15) synthesized by interconversion of enmein were assayed by the rice seedling test.

Publisher Summary The gibberellins are now recognized as being an important group of plant hormones, regulating growth and morphogenesis, distinct chemically and functionally from the more familiar indole auxins. Nine structurally related gibberellins are known (structures I-IX). They are conventionally named gibberellins A 1 to A 9 .

Mechanistic action of gibberellins in legume nodulation.
Journal of Integrative Plant Biology, 2014Legume plants are capable of entering into a symbiotic relationship with rhizobia bacteria. This results in the formation of novel organs on their roots, called nodules, in which the bacteria capture atmospheric nitrogen and provide it as ammonium to the

Gibberellin Receptor and Its Role in Gibberellin Signaling in Plants
Annual Review of Plant Biology, 2007Gibberellins (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 ...

Physiologia Plantarum, 1997
Research on gibberellin (GA) mutants is reviewed, focusing on reports, published since 1993. The mutants have usually been identified via a shoot elongation screen. This screen exposes mutations influencing GA synthesis, deactivation and reception, and also those acting further down the elongation pathway.

Chromatography of gibberellins
Journal of Chromatography A, 1994Abstract The recent literature on the use of chromatography in the analysis of gibberellins in plants is reviewed. Particular emphasis is placed on the application of solid-phase purification techniques, immunoaffinity chromatography, HPLC, GC-MS and LC-MS.

Plant Growth Regulation, 1993
Data on the occurrence of free and conjugated gibberellins in different tribes of Gramineae are compiled and discussed with regard to their biosynthetic pathways. From the gibberellins detected so far the functioning of both the early 13-hydroxylation and the non-3,13-hydroxylation pathway of GA biosynthesis in gramineous plants can be deduced and the ...
