What is plant biotechnology?
Products on the market
Benefits of biotechnology
A precise process in which scientific techniques
are adopted to develop useful and beneficial plants.
Using plant biotechnology, a single gene may be added to the strand.
(only desired gene is transferred)
Traditional plant breeding
DNA is a strand of genes, much like a strand of pearls. Traditional plant breeding combines many genes at once.
(many genes are transferred)
Single cell has the ability to regenerate into a whole plant
Any plant organ can serve as an explant to initiate cultures
Many different explants can be used, depending on the plant species and its favored method of regeneration as well as the method of transformation
Select transgenic embryos
using GFP/NPT II system
