[Comparison of the molecular and genetic map of the 2B6-2B7-8 of Drosophila melanogaster X-chromosome].
Molecular and genetic data were compared for the 2B6-2B7-8 region of the Drosophila melanogaster X chromosome. This region contains the dor (deep orange) and swi (single wing) genes influencing ecdysterone-dependent gene expression. Genes which had not been identified previously by genetic methods were shown to be present in this region. Two novel loci, designated a6 and b6, were characterized in detail. Both genes are expressed throughout Drosophila embryogenesis. The product of b6 has a homology with mammalian pentraxins. This is the first Drosophila gene found to contain the pentraxin motif.
