  • Title: Agrobacterium-mediated transformation of Bangladeshi Indica rices.
    Author: Al-Forkan M, Power JB, Anthony P, Lowe KC, Davey MR.
    Journal: Cell Mol Biol Lett; 2004; 9(2):287-300. PubMed ID: 15213809.
    Abstract:
    Morphologically normal, fertile transgenic plants were obtained by co-culturing embryogenic calli of the Bangladeshi Indica rice cultivars BR26 and Binni with Agrobacterium tumefaciens strain LBA4404 carrying the super binary vector pTOK233. Acetosyringone (100 microM) in the medium during co-culture (25-28 degrees C) and selection on hygromycin B (50 mg l(-1)) were essential for efficient transformation. Stable integration and expression of beta-glucuronidase, neomycin phosphotransferase and hygromycin phosphotransferase genes in regenerated plants were confirmed by histochemical and fluorometric assays, ELISA and Southern analysis. Two to 3 copies of T-DNA were integrated into regenerated plants; transgene expression did not correlate with gene copy number. Mendelian segregation of transgenes occurred in T1 seed progeny.
