【Abstract】 The lower osmotic-centrifugal method was used to transfer the DNA isolated from PBI 121 and purple rice into embryonic cells of rice and wheat. By the detection of X-Gluc, the brief expression of the GUS gene had been observed, this fact indicating that it had been transfered into rice cells. At the same time, the regenerated wheat plants with purple color were obtained as well.The results showed that the method may be an efficient method by which foreign DNA can be directly transferred into plant cells with wall.更多还原
