Uses

Used in Agriculture:
Gibberellin A13 is used as a growth regulator for promoting cell elongation, seed germination, and fruit development in plants. It helps in overcoming dormancy, improving crop yield, and enhancing stress resistance in various plant species.
Used in Plant Tissue Culture:
In the field of plant tissue culture, Gibberellin A13 is used as a growth factor to stimulate the growth and differentiation of plant cells, tissues, and organs. It aids in the successful propagation of plants through in vitro techniques, such as micropropagation and organogenesis.
Used in Dwarfism Research:
Gibberellin A13 is used as a research tool in studying the genetic basis of dwarfism in plants. By manipulating the levels of Gibberellin A13, scientists can gain insights into the molecular mechanisms underlying plant growth and development, which can lead to the development of new strategies for crop improvement.
Used in Stress Tolerance:
Gibberellin A13 is used to enhance the stress tolerance of plants, particularly under environmental stress conditions such as drought, salinity, and temperature extremes. By modulating the levels of Gibberellin A13, plants can be made more resilient to these stress factors, leading to improved crop performance and productivity.
Used in Plant Hormone Research:
Gibberellin A13 is used as a model compound in the study of plant hormone action and signaling pathways. Understanding the role of Gibberellin A13 in plant growth and development can provide valuable information on the complex regulatory networks that control plant responses to various environmental cues and stress factors.

Influence of electron transport proteins on the reactions catalyzed by Fusarium fujikuroi gibberellin monooxygenases

The multifunctional cytochrome P450 monooxygenases P450-1 and P450-2 from Fusarium fujikuroi catalyze the formation of GA14 and GA4, respectively, in the gibberellin (GA)-biosynthetic pathway. However, the activity of these enzymes is qualitatively and quantitatively different in mutants lacking the NADPH:cytochrome P450 oxidoreductase (CPR) compared to CPR-containing strains. 3β-Hydroxylation, a major P450-1 activity in wild-type strains, was strongly decreased in the mutants relative to oxidation at C-6 and C-7, while synthesis of C19-GAs as a result of oxidative cleavage of C-20 by P450-2 was almost absent whereas the C-20 alcohol, aldehyde and carboxylic acid derivatives accumulated. Interaction of the monooxygenases with alternative electron transport proteins could account for these different product distributions. In the absence of CPR, P450-1 activities were NADH-dependent, and stimulated by cytochrome b5 or by added FAD. These properties as well as the decreased efficiency of P450-1 and P450-2 in the mutants are consistent with the participation of cytochrome b5:NADH cytochrome b5 reductase as redox partner of the gibberellin monooxygenases in the absence of CPR. We provide evidence, from either incubations of GA12 (C-20 methyl) with cultures of the mutant suspended in [18O]H2O or maintained under an atmosphere of [18O]O2:N2 (20:80), that GA15 (C-20 alcohol) and GA24 (C-20 aldehyde) are formed directly from dioxygen and not from hydrolysis of covalently enzyme-bound intermediates. Thus these partially oxidized GAs correspond to intermediates of the sequential oxidation of C-20 catalyzed by P450-2.
