• To optimize Mu insertion site amplification and assess its performance with complex genomic templates.

Main Methods:

• Developed a novel detection method for amplified genomic sequences.
• Applied the method to optimize Mutator (Mu) transposon insertion site amplification in maize.
• Tested amplification efficiency using templates from increasing numbers of Mu-active maize plants.

Main Results:
