Résumé : Production of mutants by genetic transformation is one alternative to dissect the response to hormonal treatment. Ethylene is an important plant hormone involved in latex production. Transgenic Hevea brasiliensis plants overexpressing an ethylene mutant receptor etrl -1 from Arabidopsis thaliana were regenerated. These plants did not show any morphological response the ethephon stimulation. This plant material is a source of information to understand the role of ethylene in Hevea brasiliensis.
