DNA from the Bacillus subtilis temperate bacteriophage phi do7 was found to efficiently transfect B. subtilis protoplasts; protoplast transfection was more efficient than competent cell transfection by a magnitude of 10(3). Unlike competent cell transfection, protoplast transfection did not require primary recombination, suggesting that phi do7 DNA enters the protoplast as double-stranded molecules.
已发现来自枯草芽孢杆菌温和噬菌体phi do7的DNA能有效地转染枯草芽孢杆菌原生质体;原生质体转染比感受态细胞转染效率高10^3倍。与感受态细胞转染不同,原生质体转染不需要初次重组,这表明phi do7 DNA以双链分子形式进入原生质体。
