Transposable elements are the main components of grass genomes, especially in Triticeae species. In a previous analysis, we identified a very short element, Morgane_CR626934-1; here we describe more precisely this unusual element. Morgane_CR626934-1 shows high sequence identity (until 98%) with ESTs belonging to other possible small elements, expressed under abiotic and biotic stress conditions. No putative functional polyprotein could be identified in all of these different Morgane-like sequences. Moreover, elements from the Morgane_CR626934-1 subfamily are found only in wheats and Agropyrum genomes and among these species, only Ae. tauschii and T. aestivum present a high copy number of these elements. They are highly conserved in wheat genomes (95.5%). Based on the uncommon characteristics of the described Morgane-like elements, we proposed to classify them in a new group within the Class I LTR retrotransposon, the Morgane group.
