Using rice to understand the origin and amplification of miniature inverted repeat transposable elements (MITEs)

Abstract

Recent studies of rice miniature inverted repeat transposable elements (MITEs), largely fueled by the availability of genomic sequence, have provided answers to many of the outstanding questions regarding the existence of active MITEs, their source of transposases (TPases) and their chromosomal distribution. Although many questions remain about MITE origins and mode of amplification, data accumulated over the past two years have led to the formulation of testable models.
