a loss-of-function mutation of isoform ga2ox2 causes an increase in gibberellin 4 levels and partly suppresses the germination inability during dark imbibition after inactivation of phytochrome. The efficiency of deactivation of exogenous gibberellin 4 by the enzyme is dependent on light conditions |

ectopic expression of gibberllin 2-oxidase in wheat decreases the content of bioactive gibberellins and produces a range of dwarf plants with different degrees of severity. The dwarf phenotype is stably inherited over at least four generations and includes dark-green leaves, increasing tillering and, in severe cases, a prostrate growth habit. Expression of gibberlic acid biosynthesis genens TaGA20ox1 and TaGA3ox2 is up-regulated ant that of two alpha-amylase genes down-regulated in scutella of semi-dwarf lines. The phenotypes are restored to normal by application of gibberellin 3 |

expression of isoform PcGA2ox1 in Solanum melanocerasum and Solanum nigrum results in transgenic plants with a range of dwarf phenotypes associated with a severe reduction in the concentrations of biologically active gibberellins 1 and 4. Flowering and fruit development are unaffected. Transgenic plants contain greater concentrations of chlorophyll b and total chlorophyll, although chlorophyll a and carotenoid contents are reduced |

isoform GA2ox1 overexpressing transformants exhibit a dwarf phenotype, reduced stolon growth and earlier in vitro tuberization. Transgenic plants with reduced expression of GA2ox1 show normal growth, an altered stolon swelling phenotype, and delayind in vitro tuberization. tubers of Ga2ox1 suppression clones contain increased levels of gibberllin 20 |

isolation of a CaMV 35S-enhancer activation tagged mutant, H032, showing an increased level of OsGA2ox6 mRNA compared to the wild-type plants. RNAi and ectopic expression analysis of OsGA2ox6 show that the dwarf trait and the decreased levels of bioactive GAs in the H032 mutant are a result of the upregulation of the OsGA2ox6 gene. The H032 mutant retains normal flowering and seed production |

loss-of-funtion mutation of GA2ox7 suppresses the dwarf phenotype of DWARF AND DELAYED FLOWERING 1 (DDF1) mutants, indicating that their gibberellin deficiency is due to overexpression of GA2ox7, DDF1 activates the promoter of GA2ox7 in leaves. Under high-salinity stress (250 mM), osmotic stress (300 mM mannitol) GA2ox7 is unregulated and slightly unregulated under the stress hormone abscisic acid (100 microM), the GA2ox7 loss-of-function mutant is less growth retarded than the wild-type under high-salinity stress |
