The genus R. Br. has been an important horticultural plant in the family Caprifoliaceae. However, due to the lack of efficient molecular markers and conservation efforts in recent decades, accompanied with deforestation, the germplasm resources are under severe threat, yet the systematic position of is not clearly understood. In the present study, we analyzed the complete chloroplast (cp) genome of (Graebn.) Rehd., which represents the first reported case of . It was 155,584 bp in length, comprising a pair of 23,434 bp inverted repeat regions (IRs) separated by a large single-copy (LSC) region (89,521 bp) and a small single-copy (SSC) region (19,062 bp). Phylogenetic analysis supported the monophyly of Caprifoliaceae and suggested that was closely related to and . This complete chloroplast genome will contribute to further studies on population genetics, phylogeny, and conservation biology in .

Transfer RNAs (tRNAs) are noncoding RNAs involved in protein biosynthesis and have noncanonical roles in cellular metabolism, such as RNA silencing and the generation of transposable elements. Extensive tRNA gene duplications, modifications to mature tRNAs, and complex secondary and tertiary structures impede tRNA sequencing. As such, a comparative genomic analysis of complete tRNA sets is an alternative to understanding the evolutionary processes that gave rise to the extant tRNA sets.

Background: Stemona tuberosa, a vital species in traditional Chinese medicine, has been extensively cultivated and utilized within its natural distribution over the past decades. While the chloroplast genome of S. tuberosa has been characterized, its mitochondrial genome (mitogenome) remains unexplored.

, native to North America, is an invasive species in many areas of the world, where it causes serious damage to natural ecosystems and economic losses. However, a dearth of genetic resources and molecular markers has hampered our understanding of its invasion history. Here, we assembled 40 complete chloroplast genomes of species, including 21 individuals, 15 individuals, and four individuals, the sizes of which ranged from 152,412 bp to 153,170 bp.

Within the coral reef habitat, members of the Symbiodiniaceae family stand as pivotal symbionts for reef-building corals. However, the physiological response of Symbiodiniaceae on microplastics are still poorly understood. Research conducted in this investigation assessed the harmful impact of polystyrene microparticles (PS-MPs) on Cladocopium goreaui, a Symbiodiniaceae species with a broad distribution.

Background: Tea-oil Camellia within the genus Camellia is renowned for its premium Camellia oil, often described as "Oriental olive oil". So far, only one partial mitochondrial genomes of Tea-oil Camellia have been published (no main Tea-oil Camellia cultivars), and comparative mitochondrial genomic studies of Camellia remain limited.
Results: In this study, we first reconstructed the entire mitochondrial genome of C.
