Gibberillic acids (GA) are important plant growth hormones that promote plant cell growth and elongation. Gebberillins promote rapid stem and root growth, induce mitotic division and initiate (break dormancy) and increase seed germination rates. The gibberellins are also involved in processes such as gravitropism, tensioning and floral display.

Control over cell growth by mobile regulators underlies much of eukaryotic morphogenesis. In plant roots, cell division and elongation are separated into distinct longitudinal zones and both division and elongation are influenced by the growth regulatory hormone gibberellin (GA). Previously
Environmental changes during seed production are important drivers of lot-to-lot variation in seed behaviour and enable wild species to time their life history with seasonal cues. Temperature during seed set is the dominant environmental signal determining the depth of primary
Genetically identical plants growing in the same conditions can display heterogeneous phenotypes. Here we use Arabidopsis seed germination time as a model system to examine phenotypic variability and its underlying mechanisms. We show extensive variation in seed germination time variability
Several pathways conferring environmental flowering responses in Arabidopsis (Arabidopsis thaliana) converge on developmental processes that mediate the floral transition in the shoot apical meristem. Many characterized mutations disrupt these environmental responses, but downstream developmental processes have been more refractory to
Seed production temperature regulation of primary dormancy occurs through control of seed coat phenylpropanoid metabolism
