Hi Don,
Is one of your groups the Osiris gene cluster (so named in
Drosophila)? We are starting some exploratory work on that gene family
because six members were up-regulated in one of our experiments. We've
noted a remarkably strong one-to-one conservation with Drosophila for
a gene family of that size (~20 members), but haven't yet checked the
other arthropod genomes. Although of unknown function, that gene
cluster is notable for underlying a haploid and triploid lethal locus
in Drosophila (DR Dorer, JA Rudnick, EN Moriyama, AC … - Genetics,
2003), it would be interesting to see how the haplodiploid species
differ in that regard (presumably they must differ!).
