Three Roles for Gibberellin in Flowering

  • Rod King
Conference paper


Seasonal flowering of plants involves responses to many environmental signals including changes in irradiance, temperature and daylength. The range and complexity of environmental inputs is summarized by Thomas and Vince-Prue (1997) but integrating this information into plant response has only begun recently. Genetic studies of flowering time in Arabidopsis (Simpson and Dean, 2002) highlight a network of interacting pathways involving plant response to daylength, vernalization, photosynthetic input and gibberellin (GA) and a fifth, autonomous pathway, whereby the plant progresses to flowering in the absence of external signals.
