The structure of StBEL genes drawn to scale, according to the alignment of cDNA sequences against the corresponding genomic sequences. The cDNA sequence for the new StBELs was obtained by RT-PCR with gene-specific primers in combination with both 5′ and 3′ RACE and by utilizing genome sequence as needed. All genomic sequence for the StBEL family was obtained from sequence data from the Potato Genome Sequencing Consortium website (http://solanaceae.plantbiology.msu.edu). The conserved internal second and third exons representing coding sequence are indicated by arrows on the BEL5 gene structure.
