This study presents, for the first time, the complete mitochondrial genome of the Common Dace (Leuciscus leuciscus (Linnaeus 1758)), in association with a voucher specimen from the Swedish Natural History Museum. The complete mitogenome length is 16,603 bp and comprises 13 protein-coding-genes (PCGs), 22 tRNAs, 2 rRNAs, and one non-coding control region. A maximum likelihood phylogenetic reconstruction based on 13 PCGs of Leuciscids species confirm the monophyly of the Leuciscus genus. Furthermore, this reconstruction has corroborated the placement of other Leuciscus species in this genus as L. leuciscus is the type species of this genus.

Genomic resources for Barringtonia asiatica (L.) Kurz, a pantropical beach forest species native to the Philippines, have not been published to date, despite its medicinal importance and potential for biomedical applications. In this study, we assembled and characterized the first complete chloroplast genome of B. asiatica using Illumina paired-end sequencing technology. It displayed a typical quadripartite structure with a sequence length of 158,794 bp, comprised of a large single copy of 88,196 bp, small single-copy of 18,448 bp, and a pair of inverted repeat regions of 26,075 bp each. The cp genome contained 35 tRNA genes, eight rRNA genes, and 86 protein-coding genes with an overall GC content of 36.8%. Phylogenetic analysis revealed a close evolutionary relationship between B. racemosa and B. fusicarpa, forming a monophyletic group with B. asiatica with high bootstrap support, thereby enhancing our understanding of the phylogeny, systematics, and genetics of Asian Lecythidaceae species.

Aster scaber Thunb. (1784) is primarily distributed in eastern Asia, has a total length of 152,778 bp and consists of a large single copy (LSC) region of 84,517 bp, a small single copy (SSC) region of 18,277 bp, and two inverted repeat (IRs) regions of 24,992 bp . The GC content is 37.31%. A total of 133 genes were annotated, including 88 protein-coding genes, 8 rRNA genes, and 37 tRNA genes. Phylogenetic analysis using the maximum likelihood method showed that A. scaber is closely related to Aster species. This study provides chloroplast genome resource for further research on the phylogenetics and resource development of A. scaber.

Hemisteptia lyrata, widely distributed in China, has a 152,467 bp chloroplast genome with a large single-copy (LSC) region of 83,473 bp, a small single-copy (SSC) region of 18,594 bp, a pair of inverted repeat regions (IRs) of 25,194 bp in length. The GC content is 36.46%. A total of 133 genes were encoded, of which 88 were protein coding genes, eight were rRNA genes, and 37 were tRNAs. The phylogenetic analysis using the maximum-likelihood method showed that H. lyrata is closely related to the species in Saussurea. This study provides genomic resources for phylogenetic genetics and resource exploitation of H. lyrata.

The genus Sinosenecio B. Nordenstam (1978) is a challenging taxonomic group with complex infrageneric relationships. Here, we newly report the plastid genome of S. eriopodus (Cumm.) C. Jeffrey & Y. L. Chen (1984). Whole genome exhibited a typical quadratic structure with a total size of 151,212 bp and 132 genes. We revealed for the first time that the matK and rpoA were positively selected genes within Sinosenecio. Phylogenetic reconstruction based on whole plastid genome sequences indicated that S. eriopodus was not clustered into a monophyletic clade with members belonging to the S. oldhamianus group of Sinosenecio but rather was closely related to some genera in the subtribe Tussilaginae s.s. of Asteraceae.

Hemerocallis cultivar Small orange lamp is a hybrid variety. Its whole chloroplast genome was 156,053 bp in size, consisting of 135 genes in total, including 89 mRNA genes, 38 tRNA genes, and 8 rRNA genes. The chloroplast genome contained a large single copy region (LSC 84,805 bp), a small single copy region (SSC 18,510 bp) and a pair of inverted repeats (IRa and IRb 26,369 bp). The overall GC content was 37.34%. Phylogenetic analysis showed that Hemerocallis lilioasphodelus and H. cultivar Small orange lamp are most closely related. This will provide valuable reference for further research on the genetic information of plants in the Hemerocallis.

The complete mitochondrial genome sequence of Dendrodoris krusensternii (J. E. Gray, 1850) was determined using next-generation sequencing. The complete mitochondrial genome of D. krusensternii is 14,361 bp long, comprising 13 genes, including 13 protein-coding genes (PCGs), 22 transfer RNAs, and two ribosomal RNAs. The nucleotide composition was estimated: 28.7% A, 14.8% C, 19.6% G, and 36.9% T. Phylogenetic analysis was performed using the maximum likelihood method (including 13 PCGs). D. krusensternii is related to the Phyllidiidae (superfamily Phyllidioidea), suggesting a distinct phylogenetic placement within Nudibranchia. This study represents a genomic resource, contributing to molecular studies on the evolution of the Dendrodorididae.

Oxyceros horridus Lour. 1790, valued for ornamental and medicinal properties, has been extensively utilized in traditional medicinal in Vietnam. This study assembled and characterized the first chloroplast of Oxyceros horridus, consisted of 155,333 bp with a GC content of 37.5%. The genome included 130 annotated genes (including 85 protein-coding genes, 37 tRNA genes, and 8 rRNA genes), exhibited a typical quadripartite structure consistent with those found in other members of the Rubiaceae family. Phylogenetic analysis placed O. horridus in Ixoroideae subfamily, closely related to Fosergia shweliensis and Gardenia tenophylla. This study enriches cp genome data and phylogenetic insights within Rubiaceae.

Vaccinium oldhamii Miquel 1866 is a deciduous shrub native to Northeast Asia, including Korea, China, and Japan. Its polyphenol-rich edible berries may aid in managing chronic diseases. Despite its importance, the mitogenome of this species remains understudied. This study assembled the complete mitogenome, consisting of 626,941 bp with 45.34% GC content, using NOVOPlasty and Illumina sequencing. The genome includes 38 protein-coding genes, 24 tRNA genes, and three rRNA genes. Phylogenetic analysis revealed a close relationship with V. macrocarpon. This mitogenome provides a valuable resource for phylogenomic studies and insights into evolutionary relationships within the Vaccinium genus and the Ericales order. Vaccinium oldhamii Miquel 1866 is a deciduous shrub in the Ericales and the Ericaceae and is native to Northeast Asia including Korea, China, and Japan. Particular emphasis has been placed on the edible berries of Vaccinium species and their use as dietary supplements. Specifically, the edible berries of V. oldhamii contain high levels of polyphenols, which may aid in preventing and managing chronic diseases. However, the mitogenome sequence of this species, a valuable resource for studying evolutionary relationships and genetic diversity within the Vaccinium genus, has not been thoroughly investigated. In this study, the complete mitochondrial genome sequence of V. oldhamii was assembled into 626,941 bp circular nucleotides with a GC content of 45.34% using NOVOPlasty and Illumina sequencing data. The comprehensive annotation for mitogenome of V. oldhamii revealed that the mitogenome comprises 38 known protein-coding genes, 24 tRNA genes, and three rRNA genes. Phylogenetic analysis using ML method showed that this species is closely related to the V. macrocarpon. This newly sequenced mitochondrial genome offers a valuable resource for phylogenomic analysis and will enhance our understanding of evolutionary relationships within the Ericales order and/or the Vaccinium genus.

This study aimed to examine the complete mitogenome sequence of Sicista caudata Thomas, 1907. A circular double-stranded structure made up the mitochondrial genome of S. caudata. The complete length of the mitochondrial genome was 16,629 bp. The mitochondrial genome of S. caudata included 13 protein-coding genes, one control region, 22 tRNA genes, two rRNA genes, and one origin of L-strand replication. S. caudata was supported by bootstrap values of 100%. This study verified the evolutionary status of S. caudata in the Superfamily Dipodoidea at the molecular level.
