Abstract__ Background Gibberellins GA are plant hormones that can regulate germination elongation growth and sex determination. They ubiquitously occur in seed plants. The discovery of gibberellin receptors together with advances in understanding the function of key components of GA signalling in Arabidopsis and rice reveal a fairly short GA signal transduction route. The pathway essentially consists of GIDl gibberellin receptors that interact with F-box proteins which in turn regulate degradation of downstream DELLA .
