Transposable elements and the evolution of gene expression.
Most plant genomes are populated with enormous quantities of transposable elements (TEs) or sequences derived from TEs. The impact of TEs on their host has been addressed by characterizing mutations of the maize waxy and R genes caused by TE insertions. Association between a new class of TEs (called MITEs) and normal plant genes is also reviewed. The notion that different classes of TEs have found their respective niches in the maize genome is discussed.
