Several microorganisms possess the capacity of synthesizing gibberellins (GAs) in axenic culture. GA concentrations in the range of approximately 20 to 200 milligrams per litre of culture filtrate are produced by wild-type strains of the following fungi: Gibberella fujikuroi (GA3, GA4, GA7, GA1 and others), Sphaceloma manihoticola and other species of this genus (GA4, GA9 and others), Phaeosphaeria sp. (GA1, GA4, GA9 and others). Neurospora crassa is capable of producing GA3 in the range of… 
Isolation and characterization of gibberellic acid (GA3) producing rhizobacteria from sugarcane roots
Received: 23-05-2017, Revised: 19-06-2017, Accepted: 24-06-2017 Gibberellic acid (GA3) is an important plant hormone controlling plant’s growth and development. It is being widely used in
Endophytic fungal association via gibberellins and indole acetic acid can improve plant growth under abiotic stress: an example of Paecilomyces formosus LHL10
TLDR
The results reveal that mutualistic interactions of phytohormones secreting endophytic fungi can ameliorate host plant growth and alleviate adverse effects of salt stress.

TLDR
This review concentrates mainly on the fungal biosynthetic pathway, the genes and enzymes involved, the regulation network, the biotechnological relevance of recent studies, and on evolutionary aspects of GA biosynthesis genes.
ROLE OF ENDOPHYTE CHAETOMIUM GLOBOSUM LK 4 IN GROWTH OF CAPSICUM ANNUUM BY PRODUCION OF GIBBERELLINS AND INDOLE ACETIC ACID
Endophytic fungi represent a trove of unexplored natural source of plant hormones like gibberellins (GAs) and indoleacetic acid (IAA). In present study, we isolated eight endophytes from the roots of
Characterization of gibberellin producing strains of Fusarium moniliforme based on DNA polymorphism
TLDR
Investigations in gibberellins and genetic relatedness by random amplified polymorphic DNA may find an application in the diagnosis of unknown Fusarium species and in distinguishing isolates of Gibberella fujikuroi within the section of Liseola.
Isolation and Characterization of Actinomycets Producing Gibberellic Acid
TLDR
It is perceived that actinomycetes isolated from temperate regions have the higher capabilities to produce gibberellins, and one on spreading’s such isolates act in the fields eventually may result in the higher agricultural yields.
Endophytes Aspergillus caespitosus LK12 and Phoma sp. LK13 of Moringa peregrina produce gibberellins and improve rice plant growth
Two new strains of endophytic fungi were isolated from the bark of Moringa peregrina and identified as Aspergillus caespitosus LK12 and Phoma sp. LK13. These endophytes were identified through
Techniques to Study Microbial Phytohormones
TLDR
The present review focuses on the techniques used for isolation and purification of microbial phytohormones, including auxin, gibberellin, cytokinins, ethylene and abscisic acid.
Inductive effect produced by a mixture of carbon source in the production of gibberellic acid by Gibberella fujikuroi
TLDR
In this investigation, glucose-corn oil mixture was used as a carbon source on the basis of 40 g of carbon in a 7 L stirred tank bioreactor and affected the fermentation time as well as the production of the GAs.

Inhibition of Gibberellin Production in the Fungi Gibberella fujikuroi and Sphaceloma manihoticola by Plant Growth Retardants.
TLDR
For the triazole-type compounds and tetcyclacis, a relatively distinct correlation exists in their ability to inhibit GA formation in fungal cultures, to block ent-kaurene oxygenase in a cell-free system, and to reduce shoot growth of rice seedlings.

TLDR
From a selected rice-infecting strain of Gibberella fujikuroi a plant-growth-promoting substance has been isolated in pure form, distinct in chemical properties from the gibberellins described by Japanese investigators.
Accumulation of Gibberellin A1 and the Metabolism of Gibberellin A9 to Gibberellin A1 in a Phaeosphaeria sp. L487 Culture
TLDR
The new fungal biosynthetic pathway to GA1 from GA9 via GA4 was elucidated by feeding experiments with synthetic [17-2H2]GA9 and [17.2H1]GA4.
Abscisic acid and gibberellin-like substances in roots and root nodules ofGlycine max
TLDR
The content of endogenous gibberellin (GA)-like substances of roots and root nodules of SOya, and GA production byRhizobium japonicum cultures, were investigated by a combined thin layer chromatographic (TLC)-dwarf pea epicotyl bioassay technique and suggested that rhizobial GA production may contribute to the nodule GA content.
