摘要

Flow cytometry estimates of genome sizes among species of Drosophila show a 3-fold variation, ranging from ~127 Mb in Drosophila mercatorum to ~400 Mb in Drosophila cyrtoloma. However, the assembled portion of the Muller F Element (orthologous to the fourth chromosome in Drosophila melanogaster) shows a nearly 14-fold variation in size, ranging from ~1.3 Mb to > 18 Mb. Here, we present chromosome-level long read genome assemblies for four Drosophila species with expanded F Elements ranging in size from 2.3 Mb to 20.5 Mb. Each Muller Element is present as a single scaffold in each assembly. These assemblies will enable new insights into the evolutionary causes and consequences of chromosome size expansion.
