Figure 4From: RNA editing and alternative splicing of the insect nAChR subunit alpha6 transcript: evolutionary conservation, divergence and regulationA similar hierarchy of selection efficiency of alternative exons 8 of nAChR subunit alpha6 genes among D. melanogaster (Dme), B. mori (Bmo), T. castaneum (Tca) and A. mellifera (Ame): exon 8b > exon 8a > exon 8c. Expression of alternative exons 8 is identical with its conservation. The diagram indicates amino acid conservation from multiple alignments of duplicated exon 8 sequences from orthologs in different species. 20–30 cDNA clones were sequenced for each species. The diagram also indicates nucleotide conservation from multiple alignments of duplicated exon 8 sequences from orthologs within Drosophila species.Back to article page
