    Unintended polar metabolite profiling of carotenoid-biofortified transgenic rice reveals substantial equivalence to its non-transgenic counterpart

    Substantial equivalence is a critical concept for biosafety assessment of genetically modified (GM) crops. To investigate substantial equivalence among carotenoid-biofortified GM rice and five conventional ric...

    Compositional comparative analysis between insect-resistant rice (Oryza sativa L.) with a synthetic cry1Ac gene and its non-transgenic counterpart

    Composition analysis of genetically modified crops is an important consideration in the assessment of food safety. Agb0101 (Oryza sativa L. cv. Nakdongbyeo) developed in Korea is a form of insect-resistant rice t...

    Characterization of the potato upreg1gene, encoding a mutated ADP-glucose pyrophosphorylase large subunit, in transformed rice

    The potato upreg1, which encodes a mutated ADP-glucose pyrophosphorylase (AGPase) large subunit, was introduced into rice to evaluate its potential to enhance sink-driven yield productivity in this crop. We also ...

    Auto-excision of selectable marker genes from transgenic tobacco via a stress inducible FLP/FRT site-specific recombination system

    Antibiotic resistance marker genes are powerful selection tools for use in plant transformation processes. However, once transformation is accomplished, the presence of these resistance genes is no longer nece...
