| Dripping antibiotic solution on growing point as a novel approach to screening transgenic plants |
|
|
| Abstract: |
| The two methods of screening transgenic plants,including transgenic seeds sowed in the medium with hygromycin (TSSM) and dripped hygromycin solution on the growing point of transgenic seedling (DSGPTS),were compared and analysed.The results indicated that the transgenic plants were obtained with the method of DSGPTS,when 800 mg/L of hygromycin was dripped on the growing point of transgenic seedling at its age of 4 days.PCR analysis showed that the results of both TSSM method and DSGPTS method were showing no difference.The advantage of DSGPTS method is that the transgenic seedling is safe from pollution and the percentage of survival for the transgenic seedling is high. |
