	       ABSTRACT
	       Despite the widespread prevalence of transposable
	       elements (TEs) in the genomes of higher eukaryotes, what
	       is virtually unknown is how they are able to amplify to
	       high copy numbers without being silenced and without
	       killing their host.  In this seminar I will discuss our
	       recent studies on MITEs (miniature inverted repeat
	       transposable elements), a type of class 2 element that
	       was discovered in my laboratory 20 years ago as the most
	       prevalent TE associated with plant genes.  To understand
	       how MITEs can attain high copy numbers, we succeeded in
	       identifying a MITE, mPing, in the midst of rapid
	       amplification throughout the genomes of several related
	       rice strains. Nextgen sequencing technologies are being
	       employed to determine mPing’s strategies for success and
	       to understand how mPing impacts host transcription and
	       generates phenotypic diversity.
