METHOD TO CONTROL GENE EXPRESSION IN BACTERIA, NAMELY RHIZOBIACEAE, TO IMPROVE ROOT NODULE DEVELOPMENT, NITROGEN FIXATION AND PLANT BIOMASS PRODUCTION

摘要

A promintron sequence derived from an intervening sequence of the rolA gene of Agrobacterium rhizogenes strain A4 is described. The sequence is able to dri ve gene expression within bacteroids in all stages of nodule development in ord er to obtain, over the developmental time of the nodule, a constitutive expression of the gene(s) of interest. Uses of said sequence, derived vector s and recombinant bacteria are also described.
