Transcriptional activity of PIF and Pong-like Class II transposable elements in Triticeae.

ABSTRACT:

Background

Transposable elements are major contributors to genome size and variability, accounting for approximately 70-80% of the maize, barley, and wheat genomes. PIF and Pong-like elements belong to two closely-related element families within the PIF/Harbinger superfamily of Class II (DNA) transposons. Both elements contain two open reading frames; one encodes a transposase (ORF2) that catalyzes transposition of the functional elements and their related non-autonomous elements, while the function of the second is still debated. In this work, we surveyed for PIF- and Pong-related transcriptional activity in 13 diploid Triticeae species, all of which have been previously shown to harbor extensive within-genome diversity of both groups of elements.
