Abstract: |
|||
| The invention belongs to the field of biological engineering breeding disclosing a method of increasing the conversion efficiency of Malus plants mediated by Agrobacterium using ultrasonic. Chipping the Malus octa-edged begonia leaves into small pieces, immerging in 75mg.L-1As Agrobacterium suspension with OD600 0.6 for two minutes, treating with 100 w ultrasonic, transferring to regeneration medium for resistance screening, transforming Malus octa-edged begonia leaves to obtain resistant callus and resistant seedling with a conversion rate of 2.2%. Ultrasonic technology is first applicated in the genetic transformation of Malus plants greatly enhancing transgenic efficiency of Malus plants. The application of ultrasonic assisted Agrobacterium-mediated gene transduction for transducting rolC and transforming Malus rootstock octa-edged begonia receives a 2.2% conversion efficiency, which is consumedly higher than ordinary Agrobacterium mediated method with 0.1 ~ 0.8% conversion efficiency. | |||
