| Abstract: | Amplified fragment length polymorphism (AFLP) fingerprinting is one of the most widely used molecular techniques in plant biology today. In this paper, we describe the application of the extremely sensitive nonradioactive biotin–streptavidin system to visualize AFLP fragments blotted onto nylon membranes. The protocol is tested for different plant species (from bryophytes, gymnosperms and angiosperms) and primer combinations. Advantages of this protocol over other nonradioactive detection methods are discussed, and the suitability of the method for laboratories without automated sequencing facilities are emphasized. |
