Identification of transcriptionally active transposons in Barley.

ABSTRACT:

Background

The genomes of many major crops including barley (Hordeum vulgare) consist of numerous transposons. Despite their important roles in crop genome evolution and morphological variations, most of these elements are silent or truncated and unable to be mobile in host genomes. Thus far, only a very limited number of active transposons were identified in plants.

Results

We analyzed the barley full-length cDNA (FLcDNA) sequences and detected 71 unique FLcDNAs exhibiting significant sequence similarity to the extant transposase proteins. These FLcDNAs were then used to search against the genome of a malting barley cultivar 'Morex', seven new intact transposons were identified. Sequence alignments indicated that six intact transposons contained the entire FLcDNAs whereas a
