Variation in sex-, stage- and tissue-specific expression of the amylase genes in Drosophila ananassae
Expression of the amylase multigene family of Drosophila ananassae was investigated in third-instar larvae and adults. A developmental differentiation was found between the Amy1-2 and Amy3-4 gene clusters, the former being preferentially expressed in larvae, the latter in adults. During adult life,...

| description | Expression of the amylase multigene family of
Drosophila ananassae
was investigated in third-instar larvae and adults. A developmental differentiation was found between the
Amy1-2
and
Amy3-4
gene clusters, the former being preferentially expressed in larvae, the latter in adults. During adult life, we observed a decrease in
Amy1-2
expression in males of certain strains. We have raised some arguments for the existence of irans-active regulators, acting as repressors of
Amy1-2
in adults. The putative repressors might exhibit a geographical polymorphism, with a fixed active form in Pacific regions and a polymorphic pattern in Africa, thus increasing the diversity observed in adult amylase phenotypes. A clear differentiation between the two gene clusters was also found in tissue-specific activity along the third-instar larval midgut. In the anterior midgut, only
Amy1-2
is active, while both gene groups are expressed in the posterior midgut, with an additional subzonation within it. |
