Abstract
Acquiring transgenic lines is fundamental strategy for plant gene/protein function study. How to successfully obtain the transgenic lines is a big matter with transformation methods. Now Arabidopsis floral dip transformation method is more routinely used in hundreds of laboratories because of easily operating and high successful rate. Here simplified Arabidopsis transformation protocol was described, which was commonly used in our lab and developed from several protocols.
