Genomic structure of Bm-ASH genes. The red region stands for the ORF, and the yellow region stands for non-coding regions; gDNA stands for genomic DNA; (+) and (-) show the published genomic sequences  being forward or reverse compared with the cDNAs. "?" shows the region unsequenced. The 6 bp in Bm-ASH1 indicates that there is a 6 bp uncoding region in the first exon of the gene just following the coding region, so is the 4 bp in Bm-ASH2. Genomic sequences are all from SilkDB . The name of the genomic DNA fragment in Bm-ASH1 is Scaffold002070, in Bm-ASH2 is Scaffold007910, in Bm-ASH3 is Scaffold013050, and in Bm-ase is Scaffold000880, respectively.
