Περίληψη:
We hybridized cloned DNA segments to salivary gland polytene chromosomes
of the medfly, Ceratitis capitata, and thus established molecular
markers for 24 sites on 6 out of 10 autosomal arms. An additional marker
identified a medfly repetitive element that hybridizes to approximately
100 autosomal sites as well as a granular network that is thought to
represent the X chromosome. Some of the markers correspond to 9
characterized transcription units, while 17 remain anonymous; at least 3
of the latter are restriction fragment length polymorphism (RFLP)
markers. The characterized transcription units document that chromosomal
arm 5L of C. capitata is homologous to the Drosophila melanogaster X
chromosome, in agreement with previous inferences based on the extensive
conservation of linkage groups in Diptera.
