Abstract

 

In this present study, we established an efficient Agrobacterium-transformationsystem using an inducible expression vector co-cultivated with lisianthus leaf explants. To explore the potential application of the inducible system pJCGLOX in transgenic lisianthus (Eustoma grandiflorum cv. LisaBlue). Arabidopsis FLOWERING LOCUS T (FT) gene was employed as the target gene. Genomic polymerase chain reaction (PCR) and southern blotting confirmed the presence of this transgene in the genomes of several kanamycin-resistant lines. Transcription of FT was shown to be activated in these transformants after inducing treatment, demonstrating efficacy of the inducible systems in this kind of flower.

 

Key words: Genetic transformation, inducible gene expression. Eustoma grandiflorum, CRE-lox recombination.
