dc.description | Background: The bacterial chromosome may be used to stably maintain foreign DNA in the mega-base range. Integration into the chromosome circumvents issues such as plasmid replication, stability, incompatibility, and copy number variance. The site-specific integrase IntA from Rhizobium etli CFN42 catalyzes a direct recombination between two specific DNA sites: attA and attD (23 bp). This recombination is stable. The aim of this work was to develop a R. etli derivative that may be used as recipient for the integration of foreign DNA in the chromosome, adapting the IntA catalyzed site-specific recombination system. Results: To fulfill our aim, we designed a Rhizobium etli CFN42 derivative, containing a “landing pad” (LP) integrated into the chromosome. The LP sector consists of a green fluorescent protein gene under the control of the lacZ promoter and a spectinomycin resistance gene. Between the lacZ promoter and the GFP gene we inserted an IntA attachment site, which does not affect transcription from the lac promoter. Also, a mobilizable donor vector was generated, containing an attA site and a kanamycin resistance gene; to facilitate insertion of foreign DNA, this vector also contains a multicloning site. There are no promoters flanking the multicloning site. A biparental mating protocol was used to transfer the donor vector into the landing pad strain; insertion of the donor vector into the landing pad sector via IntA-mediated attA X attA recombination thereby interrupted the expression of the green fluorescent protein, generating site-specific cointegrants. Cointegrants were easily recognized by screening for antibiotic sensitivity and lack of GFP expression, and were obtained with an efficiency of 6.18 %. Conclusions: Integration of foreign DNA in Rhizobium, lacking any similarity with the genome, can be easily achieved by IntA-mediated recombination. This protocol contains the mating and selection procedures for creating and isolating integrants. | - |
