  • Method to improve phosphate solubilization in plants
    Patent number: 9157104
    Abstract: The present invention relates to the use of a bacterium having an high indole-3-acetic acid (IAA) content for solubilizing phosphate rock (PR) in the ground, wherein said bacterium is obtained by transformation with a gene encoding an agent able to increase the IAA content.
    Type: Grant

  • Method for increasing the survival of bacterial strains of the Rhizobium genus
    Patent number: 7846708
    Abstract: The present invention describes a method for increasing the survival of the bacteria of Rhizobium genus, comprising the steps of: making the bacteria to grow in a chemically defined medium; keeping the bacteria in growth stationary phase for a proper period of time; exposing the bacteria to effective quantities of indole-3-acetic acid (IAA). Within the invention scope there is an alternative method to increase the survival of the bacteria of the Rhizobium genus by means of genetic engineering comprising the steps of: making a recombinant vector codifying enzymes able to produce IAA to express in effective way in said bacteria; making the bacteria to grow in chemically defined culture medium; keeping the bacteria in growth stationary phase for a proper period of time.

  • Method to control gene expression in bacteria, namely Rhizobiaceae, to improve root nodule development, nitrogen fixation and plant biomass production
    Publication number: 20040229365
    Abstract: A promintron sequence derived from an intervening sequence of the rolA gene of Agrobacterium rhizogenes strain A4 is described. The sequence is able to drive gene expression within bacteroids in all stages of nodule development in order to obtain, over the developmental time of the nodule, a constitutive expression of the gene(s) of interest. Uses of said sequence, derived vectors and recombinant bacteria are also described.
