| Abstract: | Transformation of anti lyc b in carrot to tobacco varieties SRI and Xanthi was done by infecting leaf plates with Agrobacterium tumefaciens carrying expression vector of the gene.GUS test and Southern hybridization revealed that the rates of transformation basing on the GUS test were all 41.7%;Southern hybridization of Xanthi plants positive to GUS test showed the transformation ratio was 67%.Analysis on the contents of lycopene and carotene in Xanthi transgenic plants indicated that there were differences not only between transgenic and non transgenic plants but also between two different transgenic plants. |

| Keywords: | tobacco anti lyc b transformation |
