The effect of introns on gene expression.

Introns are often dismissed as junk DNA, but they can have huge effects on gene expression through mechanisms that are not yet understood. I am investigating this interesting phenomenon in plants using molecular genetics, and by testing bioinformatic insights generated by Dr. Ian Korf and his group.
