Identification of transposable elements and satellite DNA in the Neotropical species Drosophila amaguana from the Ecuadorian Andean Forests.

ABSTRACT: Genome size variation in eukaryotic species is largely influenced by repetitive DNA sequences such as transposable elements (TEs), simple repeats, and satellite DNAs (satDNAs), which do not necessarily correlate with organismal complexity. In insects, TEs are crucial to evolutionary processes and are correlated with variations in genome size. In this study, we describe, for the first time, the mobilome and satellitome of Drosophila amaguana, an Ecuadorian Neotropical species with a large, unexplored genome size, to assess the contribution of these repetitive DNA sequences to its genome composition. Using a draft genome assembly of approximately 455.5 Mb, generated from Illumina short-read sequences obtained from 10 wild specimens of D. amaguana collected at the Refugio de Vida Silvestre Pa
