A diverse satellite DNA repertoire in <i>Limnoperna fortunei</i>: insights into genome structure and chromosomal organization.

ABSTRACT:

Background

The Golden Mussel, Limnoperna fortunei, represents one of the most successful aquatic invaders in South America, causing significant ecological and economic impacts. Repetitive DNA sequences, particularly satellite DNAs (satDNAs), play crucial roles in genome architecture and evolution, yet the satDNA landscape of this invasive species remains largely uncharacterized. This study aimed to comprehensively analyze the satellitome of L. fortunei using integrated computational and cytogenetic approaches.

Methods

We employed a read-clustering approach (RepeatExplorer2) to identify satDNA families from short-read genomic data. The identified families were then mapped onto the chromosome-level reference genome in silico to determine their chromosomal
