GA4 is the active gibberellin in the regulation of LEAFY transcription and Arabidopsis floral initiation.
Plant Cell 18 , 2171-2181, (2006) Flower initiation in Arabidopsis thaliana under noninductive short-day conditions is dependent on the biosynthesis of the plant hormone gibberellin (GA). This dependency can be explained, at least partly, by GA regulation of the flower meristem identity gene ... |

Gibberellin as a factor in floral regulatory networks.
J. Exp. Bot. 60 , 1979-1989, (2009) Gibberellins (GAs) function not only to promote the growth of plant organs, but also to induce phase transitions during development. Their involvement in flower initiation in long-day (LD) and biennial plants is well established and there is growing insight i... |

Effect of medium properties and additives on antibody stability and accumulation in suspended plant cell cultures.
Biotechnol. Appl. Biochem. 35 , 171-180, (2002) Factors affecting antibody accumulation and stability were investigated in transgenic plant cell cultures. Whereas IgG(1) antibody was stably maintained in media used for animal cell culture, there was a rapid loss over a period of 1-2 h of antibody added to ... |

Role of GA3, GA4 and uniconazole-P in controlling gravitropism and tension wood formation in Fraxinus mandshurica Rupr. var. japonica Maxim. seedlings.
J. Integr. Plant Biol. 50 , 19-28, (2008) GA(3) and GA(4) (gibberellins) play an important role in controlling gravitropism and tension wood formation in woody angiosperms. In order to improve our understanding of the role of GA(3) and GA(4) on xylem cell formation and the G-layer, we studied the eff... |

Micropropagation of photinia employing rhizobacteria to promote root development.
Plant Cell Rep. 26 , 711-717, (2007) An alternative protocol was developed for in vitro propagation of photinia (Photinia x fraseri Dress), an ornamental shrub, using the plant growth-promoting rhizobacteria (PGPR) Azospirillum brasilense and Azotobacter chroococcum during rhizogenesis.
