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…

Mitochondrial genome insights illuminate evolution of invasive scale insects (Coccomorpha)
Overview Invasive scale insects (Hemiptera: Coccomorpha) pose persistent threats to agriculture and ecosystems around the world. By examining the mitochondrial genomes of five invasive species collected from Guangdong Province, China, researchers gain a window into their evolutionary dynamics. The study highlights large-scale transfer RNA (tRNA) truncations and tandem repeat-driven intraspecific gene rearrangements, offering new clues…

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…

Mitochondrial Genome of Plasmodium pitheci in Bornean Orang-utans Reveals Close Relations Within Orang-utan Malaria Lineages
Background: Orang-utan malaria and the Plasmodium pitheci discovery Malaria in non-human primates (NHP) spans a diverse genus, with Plasmodium species infecting a broad host range. Among Asian NHPs, orang-utans (Pongo spp.) harbor Plasmodium pitheci and Plasmodium sylvaticum, parasites historically identified by morphology but lacking validated molecular characterization until now. The present work focuses on the…

Pitheci Mitochondrial Genome Illuminates Orangutan Malaria Lineage
New mitochondrial genome sequence of Plasmodium pitheci from Bornean orangutans The mitochondrial (mt) genome of Plasmodium pitheci, the malaria parasite morphologically identified in Bornean orangutans (Pongo pygmaeus), has now been sequenced and analyzed, providing a crucial genetic reference for this Asian NHP malaria lineage. This study fills a long-standing gap in molecular characterization, moving beyond…

Mitochondrial Genome of Plasmodium pitheci: Insights from Bornean Orang‑utan Malaria
Introduction: Plasmodium pitheci and the orang‑utan malaria puzzle Malaria parasites in non-human primates (NHP) span over 250 Plasmodium species that infect humans and other primates alike. Among Asian NHPs, orang‑utans (Pongo spp.) host several malaria lineages, including Plasmodium pitheci. Although previous work has described morphological infections and certain genetic markers, a fully validated mitochondrial (mt)…
