The Bactrocera oleae genome: localization of nine genes on the polytene chromosomes of the olive fruit fly (Diptera: Tephritidae).
Four homologous and five heterologous gene-specific sequences have been mapped by in situ hybridization on the salivary gland polytene chromosomes of the olive fruit fly, Bactrocera oleae. The nine genes were dispersed on four of the five autosomal chromosomes, thus enriching the available set of chromosome landmarks for this major agricultural pest. Present data further supports the proposed chromosome homologies among B. oleae, Ceratitis capitata, and Drosophila melanogaster and the idea of the conservation of chromosomal element identity throughout dipteran evolution.
