Details: The success strategies of transposable elements that
diversify genomes
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 mPings strategies for success and
to understand how mPing impacts host transcription and
generates phenotypic diversity.
