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…

Evolutionary insights from the mitochondrial genomes of invasive scale insects (Hemiptera: Coccomorpha): large-scale transfer RNA gene truncations and tandem repeat-driven intraspecific gene rearrange
Introduction: A genetic lens on invasive scale insects Invasive scale insects (Hemiptera: Coccomorpha) pose threats to agriculture and ecosystems worldwide. By examining their mitochondrial genomes, researchers gain insight into evolutionary processes that shape adaptation, reproduction, and dispersal. This article synthesizes recent findings on large-scale transfer RNA (tRNA) gene truncations and tandem-repeat–driven intraspecific rearrangements, revealing how…
