Novel exon combinations generated by alternative splicing of gene fragments mobilized by a CACTA transposon in Glycine max.

ABSTRACT:

Background

The recent discoveries of transposable elements carrying host gene fragments such as the Pack-MULEs (Mutator-like transposable elements) of maize (Zea mays), rice (Oryza sativa) and Arabidopsis thaliana, the Helitrons of maize and the Tgm-Express of soybeans, revealed a widespread genetic mechanism with the potential to rearrange genomes and create novel chimeric genes affecting genomic and proteomic diversity. Not much is known with regard to the mechanisms of gene fragment capture by those transposon elements or the expression of the captured host gene fragments. There is some evidence that chimeric transcripts can be assembled and exist in EST collections.

Results

We report results obtained from analysis of RT-PCR derived cDNAs of the Glycine max mutant flower
