Abstract

We have developed a rapid and simple RT-PCR based method to check the integrity of chimeric genes within plasmid constructs for plant transformation. It exploits the Agrobacterium tumefaciens-mediated transient expression of plasmid constructs in plant tissue. Total RNA was isolated from tobacco leaves co-cultivated for 3 days with Agrobacterium tumefaciens harbouring the plant transformation vectors constructed in our laboratory. First strand cDNA synthesis with oligo(dT) primers generate a pool of cDNA that was used for PCR amplification with primers specific for each of the genes present within the constructs. PCR amplification reactions were successful for all chimeric genes tested, thus confirming their intactness and suitability to be used for stable plant transformation.
