Mitochondrial Genome Evolution in Invasive Scale Insects: Large tRNA Truncations and Tandem Repeat-Driven Gene Rearrangement
Overview Invasive scale insects (Hemiptera: Coccomorpha) pose substantial threats to agriculture and native ecosystems. Recent genomic work on their mitochondrial DNA reveals striking patterns: large-scale truncations in transfer RNA (tRNA) genes and intraspecific gene rearrangements driven by tandem repeats. These discoveries not only deepen our understanding of mitochondrial genome evolution in scale insects but also…
