Two alkaline phosphatase genes, Alp-m and Alp-s, were independently cloned from the silkworm Bombyx mori. They were mapped to a small DNA region and shown to be organized in tandem. Exon-intron structures of the two genes were highly conserved, with the exception of the second intron in Alp-m, which has no counterpart in Alp-s. The similarity between the nucleotide sequences of the exons of the two genes was strikingly high (60-79%), suggesting that Alp-m and Alp-s originated from a duplication of their common ancestor gene. The intergenic sequence between the two Alp genes shows length polymorphism in different B. mori strains, which can be explained by presence/absence of two putative insertion sequences. This structural variation suggests a possible scenario for the divergence of the two Alp genes after the duplication event."}
