Previous genetic engineering of plant secondary cell walls targeted its core polymers to facilitate their extractability. The ectopic introduction of the polymer callose into poplar wood secondary cell walls modifies the ultrastructure of cellulose microfibril aggregates and suggests new avenues when considering biomass genetic engineering.
