17. Transgenic Breeding - PlantBreeding
2013/8/9· The quaternary gene pool (GP-4) does not allow any transfer of DNA between the crop of interest or other organism by mating and ual recoination. In this case the process of transgenesis must be used to insert a DNA sequence from any biological or synthetic source known as a transgeneinto the crop plant of interest.

Maize transformation utilizing silicon carbide whiskers: a …
We review here the most recently developed technique for maize transformation which involves the vortexing of silicon carbide whiskers with maize cells in the presence of plasmid DNA. Fertile transgenic plants have been regenerated following whisker-mediated transformation which is compared with the alternatives described to date, namely protoplast uptake, particle boardment and

How to Transform Microalgae - Bitesize Bio
2019/8/8· For efficient transformation of plants and microalgae in the laboratory, a binary vector system based on the principles of T-DNA transfer is used in Agrobacterium mediated transformation. The T-DNA region is loed on a T-DNA binary vector while the Vir genes which express virulence proteins required for T-DNA transfer are contained in a separate Ti plasmid (Figure 2).
