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 par...

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 biennia...

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 wa...
