(1) Background: Chironomids are biological indicators, playing an important role in monitoring and assessing the changes in water ecosystems. Mitochondrial genomes have been widely applied as a molecular marker to analyze the taxonomy and phylogeny of insects. However, knowledge of the mitogenomes of species is scarce at present, which limits our understanding of the evolutionary relationships among . (2) Methods: In our study, the mitogenomes and their basic structure of 12 species and one species were newly sequenced. Combined with reported mitogenomes, a total of 15 mitogenomes of were selected for a comparative mitogenomic analysis and phylogenetic reconstruction of . (3) Results: Each mitogenome of the species has the typical 37 genes and a control region. The basic structure of the whole mitogenomes of species is relatively conservative, and the genetic arrangements stay the same as the ancestral mitogenome. (4) Conclusions: Our study enriches the library of mitogenomes of chironomids and provides a valuable resource for understanding the evolutionary history of .

Background: Labeo fimbriatus (Bloch, 1795) is a medium-sized South Asian minor carp with ecological significance and emerging aquaculture potential, particularly in polyculture systems with Indian major carps. Despite its wide distribution, it remains underrepresented in phylogenetic studies, and limited genomic resources are available. Here, we report the complete mitochondrial genome sequence of L.

Nuclear mitochondrial DNA segments (NUMTs), which are mitochondrial DNA fragments integrated into the nuclear genome, serve as markers of evolutionary history. This study aims to enhance the detection and analysis of NUMTs by developing a script named NUMTsearcher. Utilizing the latest chromosome-level genome assemblies from various species, including human, rabbit, and six fish species, the study compares NUMTsearcher's performance against traditional methods such as LAST (Local Alignment Search Tool), BLAST (Basic Local Alignment Search Tool), BLAT (BLAST-Like Alignment Tool), and the pan-mitogenome approach, which integrates mitogenomes from diverse sources to identify fixed NUMTs in the nuclear genome.

The complete mitogenome of the common Chinese whip scorpion, (Butler, 1872) was sequenced and compared with another Uropygid mitogenome of (Lucas, 1835). Structural divergences include the absence of one tRNA-Leu and strand inversions in four protein coding genes (PCGs). All PCGs showed K/K ratios-1, which indicates purifying selection, with COI (0.

Diatoms are pivotal in global oxygen, carbon dioxide, and silica cycling, contributing significantly to photosynthesis and serving as fundamental components in aquatic ecosystems. Recent advancements in genomic sequencing have shed light on their evolutionary dynamics, revealing evolutionary complex genomes influenced by symbiotic relationships and horizontal gene transfer events. By analyzing publicly available sequences for 120 plastomes and 70 mitogenomes, this paper aims to elucidate the evolutionary dynamics of diatoms across diverse lineages.

Red root disease in rubber trees, caused by , is a prevalent and severe soil-borne disease in rubber tree cultivation areas. The pathogen exhibits complex infections, with multiple transmission pathways, making the disease highly concealed and difficult to diagnose in its early stages. As a result, prevention and control are challenging, posing a serious threat to rubber production.
