The mantled somaclonal variation of oil palm (Elaeis guineensis Jacq.) is morphologically similar to mutants defective in MADS-box genes of the B-class. Indeed in such mutants male floral organs are converted into female ones and this can be observed in oil palm flowers of both sexes.

The detrimental consequences of somaclonal variation on fruit set then oil yields and its unpredictable

incidence in clonal progenies have prompted the search for early detection markers. More generally, a better understanding of the molecular mechanisms underlying the onset and the maintenance of this variant

phenotype is needed. The mantledsomaclonal variation is observed only in clonal populations generated through somatic embryogenesis at a large commercial stage.

Thus, because of the nature of the variation, research strategy must involve two parallel approaches aimed at studying simultaneously the in vitro stages of clonal palms production (the flask) and the in

plantadevelopment of the reproductive organs which are affected by the phenotype (the flower).

On both materials a novel combination of epigenetics approaches, high-throughput sequencing technologies and bioinformatics analyses now provide new insights into a complex developmental phenomenon. Our research work also paves the way for innovation and development oriented towards end-users in the palm oil industry.
