Abstract Book - 4th B Chromosome Conference
Highlights
Moths and butterflies (Lepidoptera) with more than 180,000 species described worldwide represent one of the largest animal orders
the presence of B chromosomes has been reported in only 25 cases
we present a thorough analysis of a B chromosome in the Mediterranean flour moth Ephestia kuehniella
Summary
Moths and butterflies (Lepidoptera) with more than 180,000 species described worldwide represent one of the largest animal orders. Materials and Methods To analyse the nature and composition of the B chromosome in E. kuehniella, we used methods of molecular cytogenetics and genomics. Genomes of E. kuehniella specimens with and without B chromosomes were sequenced at low coverage using Illumina platform, and the resulting datasets were compared and processed with the RepeatExplorer pipeline. B chromosomes were reported in 11 species of Astyanax. Shape and size similarity led some authors to suggest the common origin of B chromosomes in several Astyanax species, and recent results on repetitive DNA content was consistent with this hypothesis. Materials and Methods Here we analyze the protein-coding gene content of the large metacentric B chromosome in four species of Astyanax. Whether a nondisjunction control region exists in this species as been reported for the B chromosome of rye
