This work has been carried out in several model and/or interesting species such as maize, cabbage Brassica oleracea and Arabidopsis thaliana, the fruit fly of plant biologists; in addition, the search for genes involved in floral fragrance and flower structure has been initiated in rose as well as preliminary work on the origin of flowering plants using Amborella trichopoda-core species of all current flowering plants endemic to New Caledonia.
