Transcriptional activity of transposable elements in maize.

ABSTRACT:

Background

Mobile genetic elements represent a high proportion of the Eukaryote genomes. In maize, 85% of genome is composed by transposable elements of several families. First step in transposable element life cycle is the synthesis of an RNA, but few is known about the regulation of transcription for most of the maize transposable element families. Maize is the plant from which more ESTs have been sequenced (more than two million) and the third species in total only after human and mice. This allowed us to analyze the transcriptional activity of the maize transposable elements based on EST databases.

Results

We have investigated the transcriptional activity of 56 families of transposable elements in different maize organs based on the systematic search of more than two mil
